Most newer clients prefer 5 GHz by default if the 5-GHz signal of the AP is equal to or stronger than the 2.4-GHz signal. This is different from AireOS, in which a dynamic interface (Layer 3 interface and related IP address) is required. This is because the command no ip mac-binding is not supported in the 17.3.x train. In this section you can find general recommendations for building a stable and quality RF design, which is the foundation of a stable wireless network. When configuring integration of Cisco ISE with Cisco DNA Center, RADIUS is enabled by default, and the pxGrid connection to Cisco ISE is enabled. This deployment mode should be used when each access point has a dedicated Ethernet connection. You must then manually update the device credentials on the devices for synchronization with Cisco DNA Center, or perform a rediscovery of those devices to learn the device credentials. If not configured, a SSID policy will not be applied. AVC enables you to perform real-time analysis and create policies to reduce network congestion, costly network link usage, and infrastructure upgrades. Enhance your Cisco networking solutions such as SD-Access, Zero 3 Requires purchase of additional licenses. Click the right arrow to move the devices to the Selected Devices list on the right. Assigning an IP address to the Service Port (SP) is optional but remember that the SP on the physical appliance belongs to the Management VRF, so an IP address has to be assigned accordingly. The latter is the best option to ensure that any rogue using an uncommon channel can be detected properly. Added the Resolved Bugs table for 2.3.3.5. When configuring access points, always set the primary and secondary (and optionally tertiary) controller names and IP addresses to control the AP selection during the CAPWAP join process. Certificate Authority (CA). Note: On the C9800, once the passwords are encrypted there is no mechanism to decrypt them, as a security best practice. Design your wireless network for proper coverage and maximize the Lets assume that you have named the AP accordingly as APx_floor1, where x is the AP number. Use PortFast on AP switch ports for APs in local mode, fabric mode, or FlexConnect mode doing only central switched WLANs. Support operational continuity and maintain availability during routine Cisco DNA Center may fail to create a trust-point when the system certificate contains ".local" or ".com.corp" in the common name. 3. Otherwise, the Policy Deployment failed message is displayed. As a workaround, to collect Assurance data, add a device with AES128 encryption. information has been added to the Channel Utilization chart. get dropped. Cisco recommends that the link SNR be 25 dBm or greater. This feature can prevent authentication server problems due to high load, caused by intentional or inadvertent client security misconfiguration. A null pointer exception occurs when you try to access Show Task from the Image Repository window. To verify rogue configuration on the WLC, use this command: and on the access point use this command: Rogue Detection Configuration for Slot 0: Like general rogue detection, ad hoc rogue detection is ideal in certain scenarios where security is justifiable. You can see if your network device contains a specific configuration. provided by Cisco for policy-based In general, security being the unchangeable part of a WLAN, it is configured on the WLAN profile. The outgoing interface is then chosen according to the IP routing table lookup and in this case, it would be the Wireless Management Interface (WMI) VLAN. and SD-WAN subsystems. Node in the Cisco DNA Center User Guide. This means that the client DHCP traffic gets bridged at the controller in the client VLAN mapped to the SSID or to the client via AAA override. Per-VPN QoS, adaptive QOS support, dynamic on-demand tunnel support, Hierarchical SD-WAN. ), the Catalyst 9800 supports a specific list of characters: these are the printable ASCII characters (ASCII 32-126) without leading or trailing whitespaces. The 802.1X AP feature is supported across all supported APs. Cisco Catalyst 9200, 9200CX, 9200L, 9300, 9300L, 9400, 9500, and 9500H Series switches that operate Cisco IOS XE 17.8.1 (or The CHD settings can be found by going to Configuration > Radio Configuration > RRM and then selecting the 5 GHz Band or 2.4 GHz Band tab: The default settings are recommended for most deployments. Supervisors of modular switches with single and dual engines. <0-8> Maximum number of login sessions for a single user, 0-8 (0=Unlimited). By integrating Cisco AI Endpoint Analytics with Talos, you can flag endpoints in your network that are connecting to malicious IP addresses. speed, latency, jitter, and packet loss. NETCONF is a standard based and Extensible Markup Language (XML) encoded protocol that provides the transport to communicate the YANG formatted configuration or operational data request from an application that runs on a centralized management platform (for example a laptop) to the Cisco device that a user wishes to Disaster Recovery: Re-join operation fails when witness VM tries to reconnect to disaster recovery configuration after software Interaction between 3D wireless maps and Cisco Spaces or Cisco Connected Mobile Experiences (CMX) has been improved. It is difficult to give a general recommendation, but acceptable values are around 2 seconds in most cases, and up to 30 seconds for slow clients (phones), so usually this timeout is set to 30 seconds to account for worst-case scenarios. If using the Sleeping Client feature for Web Authentication, ensure that your idle timeout is lower than the session timeout, to prevent incorrect client deletion. All rights reserved. To set filters for searching events generated on one or more Cisco SD-WAN devices: From the Cisco vManage menu, choose Monitor > Logs > Events. management of the wired or wireless access, campus, and If the anycast gateway at the parent site is created in Cisco DNA Center 2.3.3, the problem does not occur when adding the anycast gateway to the inherited site. (Initiator), Deep Packet Inspection. FXO, FXS, and FXS/DID interface support, SIP trunk to Cisco Unified Communications Manager support, voice module and SRST integration support, voice In this release, Cisco DNA Center supports the following enhancements in the System Configuration: The Proxy Config and Proxy Certificate are combined under the Proxy window. This is an important clarification related to the use of VLAN ID =1 (and VLAN name default) in the policy profile for the Catalyst 9800: The behavior is different depending on the AP mode. to complete each operation. Starting with Cisco IOS XE Release 17.3, if the policy profiles differ only for certain parameters (VLAN and ACL being the most important), then seamless roaming is allowed across policy profiles (and related policy tags). It needs to be in a specific format: AP Ethernet MAC, Policy Tag name, Site tag name, RF tag name. SN on the device label). If the device is at the Cisco DNA Essentials It is recommended that you have one to three SSIDs for an enterprise and one SSID for high-density designs. Audit logs are collected when you create, update, or delete device or feature templates, and localized or centralized, and https://www.cisco.com/c/en/us/products/collateral/software/dna-subscription-routing/nb-06-dnasw-rout-sub-aag-ctp-en.html. This is important for increasing the uptime of the whole wireless network. fails. Furthermore, compared with AireOS, the number of functionalities in the C9800 that require shutdown of the wireless network (both 5-GHz and 2.4-GHz networks) in order to apply changes has been reduced as well. For example, if WebHook Threshold equals 2, you receive two notifications for that webhook URL per minute. are incorrect for the client. Cisco devices to be provisioned simply by connecting The main purpose of the Metal QoS profile is to limit the maximum DSCP allowed on the network. of extended node, policy extended node, and supplicant-based extended node devices. Cisco DNA Center may fail to provision a Cisco Catalyst 9800 Series Wireless Controller. In Release 17.3, the Catalyst 9800 can be configured to act as a proxy for ARP traffic and respond on behalf of a registered client. highest priority. Apart from this topology, you cannot cascade a mix view the recorded messages for tracing and troubleshooting errors in process So for AAA override in SD-Access Wireless, the user can return a different Layer 2 VNID based on the user group, and that VNID is mapped on the switch to a VLAN interface (SVI) and so to a subnet and a VRF. To enable ad hoc rogue detection and reporting, use this command: The reason for enabling AAA validation for rogue clients is that the WLC will reliably and continuously check for the existence of a client on the AAA server and then mark it as either valid or malicious. Cisco DNA Center 2.2.3.4: Unable to start LAN automation. trace to file. Static IP clients are not supported with central DHCP and local split WLANs. They must be able to detect, disable, locate, and manage rogue and intruder threats automatically and in real time. Additionally, containing rogues using infrastructure APs will have a significant negative impact on wireless service during operation, unless dedicated APs are used for containment activities. the appropriate SAN values, to Cisco DNA Center. AP provisioning fails when the locally switched WLANs are provisioned on the wireless controller or APs through Cisco DNA Center. On the CLI you can also configure it on client target. In an SSO scenario, ensure that you explicitly configure the wireless mobility MAC address; otherwise, the mobility tunnel will go down after SSO. Each access point needs to be assigned three unique tags: a policy, site, and RF tag. Use of Rogue and aWIPS functionality to monitor threats in Cisco DNA Center. Perpetual software with base routing and Application visibility (name, throughput). When both If a RAP fails and goes offline, other mesh access points will join another RAP with the same Bridge Group Name (BGN) and still have a path back to the WLC. It is supported on the APs that dont have a hardware accelerated solution with a dedicated radio: Since SI is done in software and leverages the client serving radios, Cisco recommends that you disable this feature (done by default starting release 17.6.1) and you consider carefully where and when you want to turn it on. Since 1200 exceeds the maximum number of APs per site tag, and this a large roaming domain, it is recommended that you use five site tags (grouping buildings together in five virtual areas)). To download Cisco DNA Center software, go to https://software.cisco.com/download/home/286316341/type. For no security, the default port is 25; for SSL it is 465; and for TLS it is 587. business view. For process-name , specify a process from among When you are done viewing the notification, click OK. For the desired email notification, click the Edit icon. To optimize the TCP client traffic encapsulation in CAPWAP, it is recommended that you always enable the TCP Maximum Segment Size (MSS) feature, as it can reduce the overall amount of CAPWAP fragmentation, improving overall wireless network performance. near-real-time access to operational statistics. Rogue APs can disrupt wireless LAN operations by hijacking legitimate clients and using plain text, denial-of-service attacks, or man-in-the-middle attacks. For DHCP option-43 or option-17 discovery using a hostname, set the SAN field to the Cisco DNA Center hostname. This means that for traffic to be routed out of this interface, you have to configure a route in this VRF. Heres what you should know: Band select is configurable per WLAN and is disabled by default. Block risky files (executables that may cause instability or risk data leaks) or block media and video files start, because they can't retrieve their container image. Some best practices, listed in the following sections, improve efficiency in maintaining the rogue AP list and making it manageable. If an inter-controller Layer 2 roaming is desired, then its users responsibility to make sure that the network is configured so that the same IP subnet is associated to the same VLAN on both wireless controllers. Enhance your Cisco To configure automatic TPC on either the 5-GHz or 2.4-GHz network, go to Configuration > Radio Configuration > RRM and then select the 5-GHz Band or 2.4-GHz Band tab: For optimal performance, use the Automatic setting to allow the best transmit power for each radio. Then, using custom Join profiles, you can even have different credentials for different groups of APs. Finally, if there is no tag mapping configuration on the C9800, and if the APs doesnt carry any tag information, the AP is assigned the default tags. Software Support Service in the subscription software stack and OS software on the AP (requires SNTC on the WLC), and includes 24-hour TAC support and software updates and upgrades in Cisco DNA Center. A list of configured notifications is displayed in the table. maintenance, and perform disaster recovery. Automation through Cisco DNA When assigning APs to an AP Group in AireOS, the APs would reboot causing a network down for the area covered, for at least 3 minutes. Add the management interface MAC address as wireless mobility mac address as a best practice. End-users can then remotely and securely deploy their devices on this network. You should always use custom site tags with FlexConnect. This release of Cisco DNA Center supports the creation of Layer 2 virtual network only in an SD-Access wired deployment. For this type of client to become operational and be able to receive and then send traffic, you need to configure the Catalyst 9800 with the following settings: Under the policy profile you need to enable the passive-client feature, which basically instructs the WLC to disable the IP learn timeout that would prevent the client from going to RUN state: If the traffic is centrally switched (local mode or FlexConnect central switching deployment), you also need to enable ARP broadcast on the client VLAN: If the traffic is locally switched with the AP in FlexConnect mode, then you need to disable ARP proxy under the Flex profile, so that the ARP traffic can reach the passive client. 20 MHz: Permits the radio to communicate using only 20-MHz channels. When the dashboard timeout is turned off, the session will expire after 4 hours. After upgrading, advanced wireless analytics will indicate performance and capacity gains due Zone-based firewall, IPS/Snort, Public Key Infrastructure (PKI), ACL, trustworthy system, Challenge Handshake (CHAP) and Password Authentication (PAP), The Maglev registry hangs in CrashLoopBackOff state. Recommendations for setting the IP address on the WMI: Use an SVI for the WMI for the 9800 physical appliance and the 9800-CL in a private cloud. Cisco supports roaming between controllers running different Cisco IOS XE software versions, but in general, it is advisable to use equal code across the controllers in the same mobility group to ensure consistent behavior across the devices. DNA Essentials subscription license, Network Advantage Perpetual software with full routing, security, voice, and AppX capabilities, bundled available in the right pane of every online document. SSIDs are also cleared from host onboarding. The default priority value is "informational" (severity level 6), The best practice is to use rogue detection to minimize security risks, such as in a corporate environment. By default, rogue detection is enabled. the logging of AAA and Netconf syslog messages: Syslog message generated by the Cisco SD-WAN software have the following format: Here is an example syslog message. To view configuration changes made to a template, The options in the Port Assignment tab for a fabric site have been enhanced. Although the 5-GHz band offers more channels, care should be given to the overall design, as the 5-GHz channels have varying power and indoor/outdoor deployment restrictions. Not Cisco DNA Center Rogue Management and aWIPS Application Quick Start Guide. Premier license. The C9800 supports up to 72 wireless controllers in a mobility domain or list. If you need to do it (for staging or production) is recommended to limit the number of APs to 100. In addition, this release of Cisco DNA Center supports segmentation, profiling, and Assurance of wireless bridge-network virtual machines. Regenerate your external IPAM certificate with the common name (CN) value as the valid hostname or IP address. By default (if you do not set the priority value), the border node is assigned a priority value of 10. After your network has been brought up and is stable, it is recommended that you choose a longer interval, between 4 and 6 hours. In this release, Cisco DNA Center adds support for integration of Cisco SD-Access and Cisco ACI. Active alarms are alarms that are currently You can highlight switches in the Cisco DNA Center inventory by using a system beacon. When you choose Assign SGT, the following message is displayed, and no SGTs are shown: The Meraki dashboard and Firepower Management Center (FMC) show an internal error. Products & This approach allows the user to define a common policy and apply it to multiple SSIDs without reconfiguring it all the time. with an hourly offset from UTC, or vice versa, the time ranges for data aggregation in Cisco Group-Based Policy Analytics This is also important if you have defined the wireless management interface as a layer 3 port, meaning using a configuration like this: wireless management interface GigabitEthernet2. For optimal load balancing among the physical ports of the port channel, use the src-dst-mixed-ip-port option. You might need to increase these parameters for some client authentication scenarios. Here is an example for the default route: ip route vrf Mgmt-intf 0.0.0.0 0.0.0.0 . (You To set the channel width per AP, use the following command: C9800# ap name dot11 5ghz channel width 40. chronological order. You can view changes for previous and current configuration made on a template. Help ensure hardware and software authenticity for supply chain trust and Not doing this may result in Catalyst 9800 picking the wrong one and breaking access to the graphical interface. Binary trace is supported for the following Cisco SD-WAN daemons and their For best performances, you should limit the number of APs per site tag to a max of 500 APs. In the Log Files field, choose the name of the log file. The recommended way to configure DHCP relay on the Catalyst 9800 is under the Advanced tab of the SVI configuration: Configuration > Layer2 > VLAN; you can also define multiple DHCP servers and the option 82 relay settings: When using the relay function, the DHCP traffic will be sourced from the IP address of the client SVI and routed out of the interface that matches the destination (IP address of the DHCP server) in the routing table. The only benefit is that it prevents random association requests from devices trying to connect to it. The Catalyst Wireless solution is built on three The Create Fabric Site workflow has been enhanced to include options to configure Wired Endpoint Data Collection and authentication template settings. The condition is triggered when you have existing gateways present in the fabric and you then add one of the following: L2VN (L2 only without IP pool but associated to an L3VN [affected device: EdgeNode]), New flow L2VN without L3VN (affected device: EdgeNode), L2 handoff on border (affected device: BorderNode on which L2 handoff is performed). If both the device and its onboarding node are at Cisco DNA Advantage license, the device is provisioned as a policy extended network segmentation, Network Plug Unicast forwarding is not supported on the C9800-80, C9800-40, and C9800-CL medium and large template platforms. node. you to first configure SMTP and email recipient parameters. The options to choose an authentication template for a fabric site are now available in the Authentication Template tab. The setting is enabled in the WLAN profile: Disable this feature for WLANs supporting voice or video services, or for any scenario where direct client-to-client communication is required. Client timers are under the Policy Profile > Advanced tab: Starting with Release 17.4 the default session timeout is set to 86400 seconds (24 hours) and has to be considered the recommended value to apply to all releases. time to run. Note: As of release 17.6, the following protocols are supported through the Service Port (SP): HTTP/HTTPs, SSH, NetFlow, NTP, SNMP, Syslog, RADIUS, and TACACS+. with Cisco DNA Advantage license, Includes Cisco DNA Essentials, 3/5/7 year term IGMPv3 with SSM), SSM-Mapping, Multicast Source Discovery Protocol (MSDP). Manual/CLI operations or through WebUI only. From the CLI, include the logging disk or logging server commands in the device configuration. In the next popup window select Show Diff. For details, review the Cisco Catalyst 9800 Wireless ControllerAireOS IRCM Deployment Guide. This issue is also reflected in Wide Area Bonjour SDG dashlet, where the state of the affected SDG agents is Reachable, but Down. Automate configurations and deployment of networks with Cisco DNA Center. Ensure that the clients are 802.11r capable, for example, Apple iOS devices on software version 6 and above, or split WLANs. In the Alarm Name field, choose an alarm name from the drop-down list. Disable SSC validation on the AireOS appliance before moving the AP: This will make sure that the AP can join any virtual WLC. ), overlapping IPs are still not supported. Leverage the power of Machine Learning to optimize your enterprise wireless configurations on the Catalyst 9800 controller automatically, be provided with complete visibility into the benefits through an aesthetic Consider the following when you deploy the Cisco Catalyst 9000 Series switches in a daisy chain topology: A daisy chain topology can have all devices either as extended nodes or as policy extended nodes or as supplicant-based extended L2VN border config removes cts enforcements for other VLANs. On the C9800 wireless controller, the Password Strength and Management for Common Criteria feature is used to specify password policies and security mechanisms for storing, retrieving, and providing rules to specify user passwords. Automate configurations and deployment of networks with Cisco DNA Center. You can choose one of the following QoS settings for the primary traffic while creating SSIDs for enterprise and guest wireless Using AP groups to map a specific VLAN to the SSID for each group of APs. Model-driven telemetry lets you monitor your network by streaming data You can connect either the fiber SFP or ethernet RJ-45 port. Provides guided remediation for any test failures. Gives a high-level overview of the health of wired network Set the timeout for RADIUS authentication and accounting servers by entering these settings: In the Catalyst 9800, it is important to configure the dead-criteria and the deadtime timers, especially when using multiple AAA servers and applying load balancing; with these commands the Catalyst 9800 marks a non-responsive server as dead and moves to the backup server. When connecting with a native VLAN on the AP, the native VLAN configuration on the Layer 2 must match the configuration on the AP. The Catalyst 9800 supports streaming telemetry to one instance, and one instance only, of Cisco DNA Center and Cisco Prime. Automated management of SMU/Patches patching by Cisco DNA Center. Cisco Device Hardware, Software, and Module End of Life (EoX) Status. It doesn't matter whether the user exists in Cisco ISE, because the device merely looks for a response from the RADIUS server, regardless of whether authentication succeeds or or all the modules of the process. Operations that take longer than 1 minute time out. networks. Available for Cisco Catalyst 9300 and 9400 Series Switches. In the AP 360 window, under Detail Information in the RF tab, you can view a new chart called Traffic Utilization. Use the following command: C9800(config)#wireless wps rogue ap notify-rssi-deviation 5, C9800(config)#wireless wps rogue clients notify-rssi-deviation 5. Of course, it doesnt have to be a precise cut, but the recommendation is to have an equal distribution of APs, and avoid overloading few site tags, even if it would make sense from a physical location/site point of view. In the Catalyst 9800 the non-matching traffic goes in the default class and it is marked with best effort. The default is Note: On the Cisco Embedded Wireless Controller (EWC) on Catalyst Access Points, the HA implementation is slightly different: An active controller and a standby controller are running simultaneously on two Cisco Catalyst 9100 Access Points, so if the active WLC fails, the standby will automatically take over without user intervention. Create a VLAN group and add client VLANs: 2. NETCONF/RESTCONF/gRPC/YANG, Zero Touch The VLAN group pool feature will monitor the DHCP server responses and automatically stop using those VLANs with clients that fail to obtain a DHCP address assignment. on the local device. slot. TACACS+ is not enabled by default. Fastlane will trigger the following configuration: EDCA parameter set to Fastlane under Radio Configurations > Parameters > 5 and 2.4 GHz bands, The Catalyst 9800s egress priority queuing is set to prioritize voice and CAPWAP traffic applying the AutoQos-4.0-wlan-Port-Output-Policy service policy. Switch provisioning fails with the following error: Evaluation for Spring4Shell vulnerability (CVE-2022-22965). logging levels (off, low, normal, and high). IOx Applications can be deployed onto Cisco Catalyst APs, leveraging an RF USB dongle inserted into the APs USB to communicate with nearby IoT devices. A factory-default Cisco Catalyst 9200, 9200CX, 9200L, 9300, 9300L, 9400, 9500, and 9500H Series switch that operates Cisco To avoid this, the first step is to configure a specific source interface for the DHCP packets using the ip dhcp relay source-interface command: in this case you want DHCP packets to be sourced from the WMI interface (VLAN 201): Note: To support the command ip dhcp relay source-interface in conjunction with option 82 parameters, you need to be using Release 17.3.3 or higher. Note: If the customer imported third-party certificates on their Catalyst 9800, it is important to note that the private keys won't be copied by simply copying the configuration. Introduction. Includes Stealthwatch Flow Rate Cisco collects the following categories While configuring the CMX settings, do not include the # symbol in the CMX admin password. The IP-Directed Broadcast feature is supported over SD-Access transit only for unknown unicast traffic destined to silent If the fabric site is defined at the building level, you must Starting from Cisco IOS XE Release 17.6.1a and Cisco SD-WAN Release 20.6.1, for template and policy configuration changes, the Audit Logs option displays the action performed. Since the tags are saved on the AP, when the AP joins the second WLC, it will present the tags and as long as these exist on the controller, the mapping will be honored. Layer 2 and Layer 3 Routing General, SD-WAN Layer 2 and A powerful end-to-end, indoor location services cloud platform that extends platform capabilities via integrations and partner applications. Here is an example of the command output. To avoid unnecessary work by the controller data plane and prevent network loops, it is advisable to configure the trunk links between the WLC and the uplink switch(es) to only allow the required VLANs; specifically the wireless management interface VLAN and the centrally switched client VLANs. The customer leverages public IP subnets so they don't have another spare subnet to assign to clients on the same SSID, The customer is using static IP for wireless devices. The default user email suffix is appended to the username. Then measure the -67 dBm Received Signal Strength Indicator (RSSI) on the AP for the test network client during active data traffic between the AP and client. How would you distribute the APs among multiple custom site tags? If for some reason the box is in bundle mode, follow these steps to boot in install mode: 5. both the Cisco DNA Center FQDN and IP address (or NAT IP address) in the SAN field. all the VLAN information. Cisco DNA Center: Ekahau file import fails with the following API error: Unable to start LAN automation due to the following error: Supplicant-based extended node fails to onboard via Plug and Play when using the Cisco DNA Center-based onboarding flow. QoS Bi-Directional Rate Limiting (BDRL) policy with AAA override is supported for both local and FlexConnect mode. Consider a customer use case in which a university has a rule to use /22 subnets across the campus. Starting from Cisco IOS XE Release 17.6.3, the alarms alarm bfd-state-change syslog command is used to view the BFD state change syslog message for any BFD state change event in the device. To avoid any possible errors that could lead to clients being assigned to the WLCs wireless management VLAN, it is advisable not to configure any policy profile to use the wireless management VLAN, so that the related SSID will not have traffic forwarded to the management subnet. This can be done via CLI using "show logging" or checking on the web interface under Troubleshooting > Syslog section. If the profile uses the Cisco DNA Center hostname, the SAN field must be set to the FQDN of the controller. To make sure that the AAA server is actually alive after the deadtime, and to avoid sending requests to a still unreachable AAA server, you can configure an active probe under the server definition: c9800(config-radius-server)#automate-tester username probe-on. PPP over Ethernet (PPPoE), PPPoA (PPP over ATM) for DSL support, L2TPv2. Enabling Network Time Protocol (NTP) is very important for several features. as an extended node when it is in factory-default state and connected to an edge node. Get the AireOS configuration file, either uploading it via TFTP or using the show run-config commands CLI command, and save it in a text file. To export data for all audit logs to a file in CSV format,click Export. rogue on wire. For APs in local and fabric mode, the round-trip latency must not exceed 20 milliseconds(ms) between the access point and the controller. Alarms data displayed on the graph can also be looked up in the Excel file. Therefore, some of the tips might not be applicable to your installation. You can configure dual-band (XOR) radio parameters on the following APs from Cisco DNA Center: Support for 300 APs per FlexConnect Site Tag. In the WebHook Threshold field, enter the threshold value. If you are upgrading from an earlier release, FIPS mode is not supported. For the default site tag, fast and secure roaming is not supported. Cisco SD-Access and Cisco ACI Integration. Most deployments recommend that VLAN 1 be disabled. configuration or automation through Cisco DNA Center. View with Adobe Reader on a variety of devices, Cisco DNA Center Automation Events for ITSM (ServiceNow), Cisco Catalyst 9800 Series Wireless Controller, Cisco Catalyst 9800 Embedded Wireless Controller for Catalyst 9300 Series Switches, New and Changed Features in Interactive Help, Release 2.3.3, Release Notes for Cisco DNA Center, Release 2.3.3.x, Upgrade to the Latest Cisco DNA Center Release, New and Changed For the 9800-CL in a public cloud, you must use a Layer 3 port (it is automatically configured during bootstrap), meaning that there is no support for Sniffer mode AP and Hyperlocation. If you are migrating from AireOS WLC to the Catalyst 9800, the configuration file needs to be translated, as the operating systems are different. MACsec encryption, Full Flexible For example, if a wireless client-A sends an ARP packet to another wireless client-B, the Catalyst 9800 will forward the ARP packet using the unicast destination MAC B; client-B will reply and will also learn client-As MAC address. show logging profile sdwan . plus associated monitoring capabilities via vManage, SD-WAN Application Intelligence Engine (SAIE). Some features are not available in local switching mode, depending on whether the AP is in connected mode (registered to the WLC) or standalone mode (the AP has lost connection to the WLC). On the C9800, the AAA override setting is defined on the Advanced tab in the Policy profile. Pragmatic General Multicast (PGM), Router Group Management Protocol (RGMP), multicast service reflection, multicast VPN. mitigate future performance issues. The version of Cisco ISE is not 2.6 patch 1, 2.4 patch 7, or later. the device tags and device roles are assigned to a software image, the device tags take precedence. For Wide Area Bonjour, restoring a NIC-bonded cluster link in three-node HA sometimes causes Service Discovery Gateway (SDG) agents to remain in 9. discovery and advertisement at for local cache discovery and distribution functions between The security level can be None, SSL, or TLS. When building a mobility tunnel for guest anchoring, the group names can be different, and they should be different if there is no roaming between the two controllers. However, in 5 GHz, this can represent a significant increase in throughput and speed, provided you have enough 20-MHz channels available. Following are some other important considerations and recommendations: SSID level policy is applied per AP to the aggregate traffic for all clients on that SSID. each application in Cisco DNA Center, see the Cisco DNA Center Compatibility Matrix. debug operational command, vsyslogAll syslog messages from Cisco SD-WAN processes (daemons) above the configured priority value. If you need any of the optional applications, you must manually download and install the packages separately. (AAA) and configuration on the network devices. For each SNMP trap that a device generates, the device also generates a corresponding App health (router, switch, NAM based), app 360, app performance in client/device 360s (jitter, loss, latency), SD-AVC. FIPS mode is not supported for the Cisco Wide Area Bonjour application. Web1 Cisco DNA for SD-WAN and Routing subscription licenses include embedded SWSS support ONLY for the subscription functionality (vManage, vSmart, vBond, vAnalytics, Cisco Umbrella, Cisco SIG Essentials, etc.) Note: Cisco.com credentials are needed to access the configuration tool. This moves the C9800 from bundle mode to install mode. AP as a sensor is not supported in this release of Cisco DNA Center. Note: For security reasons, it may be advisable to use zero retries for EAPoL, but please validate this setting in your environment, as it may result in failed authentication in bad RF environments. Lets say you chose eight site tags, then you would distribute the 3000 APs across these tags, in this case it would be 375 APs per site tag. On the GUI, you can only set the Metal QoS per SSID. Assigning the same site tag to all the APs in the same roaming domain (the area, floors, group of floors, building where the majority of the roaming takes place) is particularly important if you require optimized fast roaming for delay sensitive applications, such as voice over WLAN. New security context and associations are established if necessary, and the client database entry is updated for the new access point. An optimal link quality would be greater than 40 dBm, but this is not always achievable in a non-line-of-sight deployment or in long-range bridges. FlexConnect deployment is optimized for remote sites or branches for a distributed enterprise. Dynamic Channel Assignment (DCA) optimizes the channel assignments to allow for interference-free operation. Minimum RSSI >-70 dBm: This criterion normally indicates that unknown rogue APs are inside the facility perimeters and can cause potential interference with the wireless network. Binary trace improves run-time performance by recording messages faster in the binary It is not recommended for retail customers or venues that are shared by various tenants, where Wi-Fi signals from all parties normally bleed into each other. Make sure you have this line aaa authorization network in your configuration, pointing to an authorization list and a server-group name. In other words, you dont have to set the mode to FlexConnect on the AP itself (as you were doing for AireOS), but simply to assign the AP to a site tag that is configured to be a remote site, and the C9800 will do the conversion automatically. It uses one network-wide faculty SSID, and since it has more than 1022 users, it needs to assign multiple client subnets to the SSID. If the SAN field in the Cisco DNA Center certificate does not contain the appropriate value, the device cannot successfully complete the Plug and Play process. For the desired email notification, click the Trash Bin icon. When a user fails to authenticate, the controller can exclude the client. For an AP in FlexConnect local switching mode: Using vlan-id 1, a client is assigned to the FlexConnect native VLAN. Cisco DNA Automation Routing and VNF Management, Advanced Radio-Aware Routing (RAR, PPPoE based-RFC 5578), mobile IP, Proxy Mobile IP (PMIP), network positioning system. Moving APs between an AireOS WLC and the C9800. Enhance your Cisco Gives a high-level overview of the health of every network device/client Priority values range from 1 to 10 (1 is the highest priority and 10 is the lowest). product; OS software updates and upgrades. If SFP is connected when RJ-45 HA is up and running, the HA pair reloads. This means that on deployments with newer client types, band select may not be necessary. WebIntroduction Cisco has recently introduced NETCONF/YANG support across the enterprise network portfolio. Configure AAA VLAN Name Override for FlexConnect Deployments on Cisco AireOS Controller. For more information on the filtering options, see the command page for Zero-touch provisioning for new device installation of Cisco devices to Traffic is routed through the border node that has the If a tag is not explicitly defined, the AP will get the default policy, site, or RF tag. real-time access to operational statistics. You can add AP zones to a network profile for wireless devices. This is a software-defined controller-based solution that enables devices to advertise and discover Bonjour services across Layer-2 domains, making it applicable to a wide variety of wired and wireless enterprise The wirelessgrouping entry can't be deleted, which causes Cisco Wireless Controller provisioning failure. An IE3400, IE3400H, and IE9300 device with Network Advantage and a Cisco DNA Advantage license is configured as a policy extended Every bridge-network virtual machine is individually authenticated and authorized by the Cisco SD-Access network. Recommendations for local switching are as follows: Connect the FlexConnect AP to the 802.1Q trunk port on the switch. AVC is supported on all C9800 wireless controller platforms. For an AP in local mode/Flex Central switching: Specifying vlan-name = default, client is assigned to VLAN 1, Using vlan-id 1, a client is assigned to the wireless management VLAN. For information on how to check the REP ring status, see the "View REP Ring This is true for both the 5-GHz and 2.4-GHz bands: In the C9800 these settings can also be configured per RF profile, which means that the user has the flexibility to assign a load balancing window to only a certain group of APs by assigning those to a specific RF profile and tag: Its recommended that you use this feature only on good coverage environments as it might have negative impact on voice or interactive video traffic. LACP is also supported starting with release 17.1. NetFlow, Cisco IOS You can choose more than one entity. Check if you have enough space in flash to download an image: 6. For FlexConnect APs, the control plane is always centralized to the central WLC, but the data plane is flexible: the client traffic can be either locally switched at the AP or centrally switched at the controller. Then, retry the Plug and Play process. Press. attacks that compromise software and firmware. Hence, roaming from foreign to anchor is not possible. Automation through This feature optimizes the alarms on Cisco vManage by automatically suppressing redundant alarms. download location and is named Audit_Logs.csv. What's New in Cisco IOS XE (SD-WAN) and Cisco SD-WAN Releases, Information About Connectivity Fault Management, View Log of Configuration Template Activities, View Messages Logged by Binary Trace for a Cisco SD-WAN Process, View Messages Logged by Binary Trace for All Cisco SD-WAN Processes. Lets take the TCP MSS Adjust setting as an example: In AireOS this is a global setting, so the same value is either applied to all the APs at each location or is left as the default. This document describes the features, limitations, and bugs for Cisco DNA Center, Release 2.3.3.x. Flex profile: Groups all settings to be assigned to a Flex AP: native VLAN, ACL mapping, and so on. NTP synchronization on controllers is mandatory if you use any of these features: Location, Simple Network Management Protocol (SNMP) v3, access point authentication, or 802.11w Protected Management Frame (PMF). For a complete list of these attributes, visit: https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-3/config-guide/b_wl_17_3_cg/m_client_roaming_policy_profile.html. Note: The above information applies to N+1 redundancy as well. The features in 2.3.2.x are rolled up to 2.3.3.x. Use the reference in the configuration guide: https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/config-guide/b_wl_16_10_cg/flexconnect.html#ID138. The file is downloaded to your browsers default with less mundane troubleshooting work. automation through Cisco DNA Center. TPC provides enough RF power to achieve desired coverage levels while avoiding channel interference between APs. With dual-band reporting enabled, the client receives a list of the best 2.4- and 5-GHz APs upon a directed request from the client. Send an SNMP trap to the configured trap target. Support for Mixed Type Extended Nodes in a Daisy Chain. Event-driven RRM (ED-RRM) is not on by default; its a good practice to enable it. Band select will impact the initial scan, steering clients toward 5 GHz, and so, if the client initially joins the 5-GHz band, it is more likely to stay there if there are good power levels on 5 GHz. This special character, for example, could be part of a url that you want to configure in your parameter map; if you try to type this character directly on CLI, you will see that it will not print it (but list available keywords or arguments depending on the mode you are); in this case to enter ? on CLI, you would use Ctrl+v and then type ?. To work around this problem, bring up only one tunnel per data center. This rule is recommended only for enterprise deployments that have their own isolated buildings and secured perimeters. Display devices and client connectivity from any angle or context, but no devices are displayed in the Install tab. The Radio Down issue is triggered when a radio goes down. The Cisco Catalyst 9800 Series (C9800) is the next-generation wireless LAN controller from Cisco. Cisco vManage then lists the alarm as Cleared, and the alarm state generally changes to medium or minor. This means that no matter what VLAN the SSID is mapped to on each WLC, the client will always be anchored to the first WLC it joins. If you choose Custom, a device list is displayed: In the Available Devices list on the left, choose one or more devices. Lets analyze the recommendations one by one. Lets look at an example. To provide feedback about Cisco technical documentation, use the feedback form For example, if the graph displays an alarm data (Critical 2, Major 274, Medium 4, Minor 405) with date and time as 15/Feb/2022 SD-Access devices, managed by Cisco DNA Center. Center, with suggested remediation for any issues, This setting is disabled by default, as you can verify in the GUI: To set it in the CLI, use the following command: Device(config)# ap dot11 5ghz/24ghz rrm optimized-roam. If a frame does not make it through, the client will retransmit at the next lowest data rate and so on until the frame goes through. Backup primary/backup secondary settings are configured at the WLC level. However there are some differences in the Catalyst 9800 that you should consider: You can apply a Metal profile on both egress and ingress separately. Prior to designing a network, an RF active site survey is the first step to understand your RF environment. No You can create and provision 300 APs per FlexConnect site tag on the Cisco Catalyst 9800 Embedded Wireless Controller for Catalyst 9300 Series Switches release 17.8 or later. You can add the pack to your Cisco DNA software licenses and choose the license count that fits your needs. Explore solutions; Cisco partners make the difference. The Cisco DNA Center GUI is compatible with the following HTTPS-enabled browsers: We recommend that the client systems you use to log in to Cisco DNA Center be equipped with 64-bit operating systems and browsers. Identify and check compliance of endpoints, and use AI/ML techniques to For a (guest) SSID to be tunneled from Foreign to an Anchor WLC, you must configure the policy profile accordingly: On the Foreign, you select the Anchor IP under the Policy Profile > Mobility tab and on the Anchor WLC you enable the Export Anchor functionality under the same tab, as shown here: The moment you enable the setting above, the same profile cannot be associated to a WLAN/SSID that needs to be broadcasted on APs that are joined to the Anchor controller. This means that you would have to statically configure the most capable controller to be the leader. policy creation, Application Leverage a snapshot of the overall health of these critical services all in one place, highlighting the worst-performing service server, site-level impact, and scope of end-user impact. ICMP redirects, VRRP, DHCP relay agent, SSH, traceroute, SNMP logging server. Note: Do not enable the dual-list option if using single-band clients or for deployment scenarios that use devices primarily configured for 5 GHz. Reduce the need for inter-controller roaming. The Config Difference pane displays a side-by-side view of the differences between the configuration that was originally in the templateand the Use the following configuration commands to do this: Another best practice is to configure the service tcp-keepalives to monitor the TCP connection to the box: Starting with Release 17.3, it is possible to configure HTTP/HTTPs independently for WebUI access and for redirection for Web Authentication SSIDs. Keep in mind that each application has different requirements: voice deployments have stricter requirements than data services in terms of latency and jitter; location-based deployments require a denser deployment of APs to be able to triangulate each client position; new IoT applications might impose stringent requirements for latency, etc. In the System IP field, choose the system IP of the devices, for which to view generated events, from the drop-down list. For information on enabling Bridge Mode VM for a wireless IP pool, see the Cisco DNA Center User Guide. Cisco DNA Center is using the ifSpeed OID (1.3.6.1.2.1.2.2.1.5). of global credentials. Starting 17.1, C9800 supports Device Analytics feature to enhance the enterprise Wi-Fi experience. For example, for a 9800-80 that supports 64,000 clients, the maximum DHCP bindings supported is around 14,000. Cisco Umbrella connector support, URL filtering support. For more information on what software versions support interoperability, check the Wireless Compatibility Matrix, Cisco supports inter-release controller roaming (IRCM) between the Catalyst 9800 and AireOS wireless controllers. In the upstream direction it is recommended to configure the AP to map the inner DSCP client value to the outer CAPWAP header. While adding additional edge switches to an existing fabric, Cisco DNA Center may alter the AAA configuration of an existing Cisco Wireless Controller from TACACS to RADIUS. The only required IP address for the C9800 wireless controller is the one assigned to the Wireless Management Interface (WMI). The following errors are displayed: After a disaster recovery (DR) failover, when you perform a trust re-establishment operation within 15 to 20 minutes, Cisco Network Analytics, Cisco term subscription. Deadtime specifies the amount of time the server remains in dead status after dead-criteria marks it as dead. or reconfigure the fabric site at the same level as the reserved IP address pool. Note: RLDP is supported only on 802.11ac Wave 1 APs. Cisco vManage Release 20.6.x and earlier: From the Cisco vManage menu, choose Monitor > Audit Log. Gives a high-level overview of the health of every network device/client visibility, and delivery of new services quickly on For example, the following syntax is valid: You might see the following error when editing an existing IPAM integration or when adding a new IPAM manager. extends trust, and applies policy to the device. All configuration and AP and client states are synced between active and standby. Layer 3 Routing General, SD-WAN Layer 2 and deliver optimal performance and resolve issues faster by getting the clients point of view of the network what access points it sees, the reasons for disconnections, and the current state of the user experience Download of latest KGV files fails due to a certificate change on tools.cisco.com. Please check the deployment guides for more information. Trend View Enhancement for Wireless Clients in Client Dashboard. In a Disaster Recovery deployment, the IPsec tunnel fails to establish after you upgrade to Cisco DNA Center 2.3.3 from an earlier release like 2.2.2.x or 2.2.3.x. To confirm that the status of the NTP server is synchronized, use the following command: Clock is synchronized, stratum 9, reference is 172.16.254.254. AI and machine learning technologies are implemented on Cisco DNA Center and in the AI Network This is important to ensure seamless mobility during brownfield and migration scenarios. An orange banner appears on the Cisco DNA Center GUI with the message, "Assurance services have been temporarily disrupted. For any wireless deployment, always do a proper site survey to ensure adequate service levels for your wireless clients and applications. HTTP secure server peer validation trustpoint: HTTP secure server ECDHE curve: secp256r1, HTTP secure server active session modules: ALL. Use extra caution when moving an AP from an AireOS-based appliance to a C9800-CL. It is recommended that you use Alert. This problem applies only to Cisco DNA Center being brought back to a Reader role. To ensure optimal performance over your mesh network, make sure the backhaul link quality is good. Hover over each feature for a description of the capabilities. You can now create a Layer 2 virtual network without associating a Layer 3 virtual network. Try not to have too many supported data rates so that clients can down-shift their rate faster when retransmitting. the interface group feature) to map multiple client subnets to the same SSID and assign clients in a round-robin fashion to the available VLANs in the group. 90 days of Cisco TAC support; local business hours, 8x5; Hardware All the settings are available on the GUI as well (the example below is for a 5-GHz network): By default the interval is set to 10 minutes. Cisco DNA Center does not collect client data if the connected interface is a trunk port and the neighbor is a switch. Enables policy-based automation with secure segmentation, complete standby" flow, the Configure replication step doesn't complete, leaving the Recovery site in the "Configuring Standby" state For more details, see the configuration guide: https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/config-guide/b_wl_16_10_cg/mesh-access-points.html#id_88480. You must carefully plan the process to disable or enable data rates. Link aggregation (LAG) mode is the preferred mode of operation, as it provides redundancy and additional network bandwidth. Depending on the size of your site, you may see several redundant Analytics cloud to Majorindicates that the problem needs to be looked into but is not critical enough to bring down the network. We recommend you copy and paste directly in the CLI. To enable this feature, go to the Advanced tab of WLAN configuration and enable Advertise Support and Advertise PC Analytics Support, the latter being the one for Intel devices: Application Visibility and Control (AVC) classifies applications using Ciscos Deep Packet Inspection (DPI) techniques with the Network-Based Application Recognition (NBAR) engine and provides application-level visibility into and control of the Wi-Fi network. Critical or major rogue AP alarms are classified as malicious and are detected on the network. Regularly research and investigate, and then remove, friendly rogue APs from the unclassified rogue AP list on a regular basis (weekly or monthly). Analytics (ETA)*: (No Stealthwatch License Included), Cisco Prime Use the Cisco IOS XE configuration guide for the other protocols. app- and SLA-based routing policy, VNF lifecycle management, DSL, 4G LTE, and multilink router interfaces, NTP Catalyst 9000 switches, not on legacy switches. Another way to preserve tags when moving APs from one controller to the other is to use an AP tag filter. changes made to the configuration. the maximum value reportable by this object, this object should report its maximum value (4,294,967,295) and ifHighSpeed must Note: This command needs to be run at the exec prompt (not in config mode). Cannot be purchased attacks that compromise software and firmware. When a site is down, Cisco vManage reports the following alarms: Cisco vManage displays alarms for each component that is down. back to the Cisco DNA Center wireless design. Services, Connectivity and The box will boot up, the SSO pair will be formed again, with the new box going to standby hot state. The flow of traffic from a wired source to a wireless target is known as downstream (or egress) traffic. Longer messages are truncated. To enable Wi-Fi interference awareness and configure the duty cycle to 80%, go to the DCA tab under Configuration > Radio Configuration > RRM, and go to the Event-Driven-RRM section: Dynamic Frequency Selection (DFS) was created to increase the availability of channels in the 5-GHz spectrum. Gain application visibility and control through Next-Generation automatically. Assign policies to applications based on business relevance and The exclusion timeout should be enabled, normally with exclusion set to 180 seconds (3 minutes). Here is how to configure it on the GUI: If the Rogue Location Discovery Protocol (RLDP) feature is needed, use it only with monitor mode APs, to prevent performance and service impacts to the wireless network: C9800(config)# wireless wps rogue ap rldp alarm-only monitor-ap-only. Notifications are messages that the device sends to the Cisco vManage server. Multicast-forwarding mode is the recommended setting. When the notification events that Cisco vManage receives indicate that the alarm condition has passed, most alarms clear themselves You need to make sure that the C9800 is configured with the right profiles and tags and AP mapping, so that when the AP joins it will get the right settings.
