The file is downloaded to your browsers default Cisco Catalyst 9800 Series new configuration model. Manually generated reports in Cisco DNA Center result in blank pages. 4 In a BNG or iWAG deployment, these features require a separate and distinct Broadband Feature License apart from the Cisco DNA subscription license. The Stack License workflow task is supported for Cisco Catalyst 3650 and 3850 Series switches running Cisco IOS XE 16.7.1 On the CLI you can also configure it on client target. Ensure that the clients are 802.11r capable, for example, Apple iOS devices on software version 6 and above, or split WLANs. The only exceptions would be for C9800-CL in a public cloud, where it is mandatory to use a Layer 3 port for wireless management; and for the embedded wireless in Cisco Catalyst 9000 switches, where a loopback interface is recommended. This is different from AireOS behavior: An AireOS WLC would allow seamless roaming across two AP groups mapped to different VLANs. Dashboards, overall health, network health, client health, topology, pre-canned reports, custom thresholds. slot When you have to use the same VLAN/subnet on both the Catalyst 9800 and AireOS, then is recommended to use the following releases: Cisco IOS XE code: Release 16.12.4a or 17.3.2 and above, AireOS code: Release 8.5.17x, which is the seventh maintenance release (expected in January 2021) or Release 8.10.142 and above. enabled by the tier purchased (Cisco DNA Essentials,
Using the AI RF Simulator, you can simulate changes to the current RF profile configurations and visualize the projected outcome Events generated by Cisco SD-WAN devices are collected by Cisco vManage and classified as: Criticalindicates that action needs to be taken immediately.

You might see the following error if a CA-signed certificate is revoked by the certificate authority: To correct this, obtain a new certificate from the certificate authority and upload it to System > Settings > Trust & Privacy > Trustpool. Then, using custom Join profiles, you can even have different credentials for different groups of APs. For information on how to check the REP ring status, see the "View REP Ring If you include both, set the FQDN as the first SAN value, followed appliance. At this point, go ahead and power off the VM. Perform AAA provisioning only after adjusting network device differential changes to the restored database. For the desired row, click and choose Audit Log Details. 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. Products &
The collector further analyzes the data and extract relevant information for monitoring and troubleshooting. NAC is not enabled via advanced SSID Model config when pushing to two Cisco Wireless Controllers at the same time. Click Edit next to Alarm Notifications to check whether Alarm Notifications are enabled and the Email Settings check box is checked. RP Discovery*, PIM
Enter your password if prompted. To enable this feature, go to the Advanced tab in the WLAN configuration: There is no general reason to change the default settings, but if you need to tweak the band select operations for a specific environment, do so here: RF profiles are the main mechanism to customize the RRM and RF parameters for a given set of access points. By integrating Cisco AI Endpoint Analytics with Talos, you can flag endpoints in your network that are connecting to malicious IP addresses. To obtain general networking, training, and certification titles, visit Cisco Static and dynamic routing (BGP, OSPF), routing protocol redistribution (EIGRP, OSPF, BGP), EIGRP
With the new configuration model, the TCP MSS Adjust value is set at the AP Join profile level, so the customer can evaluate the transport network at each site and decide the value that is best for a specific group of APs. This depends on the client type; for example, Cisco 8821 IP phones might have voice problems during roaming if this option is enabled, as the controller does not allow voice or signaling traffic to pass until the DHCP phase is completed. With the C9800, there are two RF profiles, one for each band, and these are assigned to the AP through the RF tag. Cisco SD-Access: Transits and Peer Networks. This is enabled globally on the controller with the CLI command: In 17.6 the feature is disabled by default for backward compatibility with previous releases, but Cisco recommends enabling it. A powerful, end-to-end, indoor location services cloud platform that
Wireless QoS policies are configured under the Policy Profile. The use of the 802.11k neighbor list can limit the need for active and passive scanning. Device health calculations. Cisco DNA Center 2.3.3: BPDU configurations keep pushing to the XTR switches even after the configurations are removed manually. The first time the AP joins a controller based on a different OS, it will have to download the image and reload, so allow for downtime. This setting can prevent a client from attacking another client connected to the same WLAN, but it is important to keep in mind that using the drop option will prevent any application that can communicate directly between clients, such as chat or voice services.

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. If your coverage is sufficient, it is a good idea to incrementally disable lower data rates one by one. It is mainly the Radio Resource Management (RRM) settings that require a shutdown of the wireless network. The number of DNS servers must not exceed three. As a workaround, you need to initiate traffic (i.e., a continuous ping) from the 9800-CL to update the MAC address in the table on the physical switch connected to the server. Configure a token on both controllers before moving the AP. Note: The above information applies to N+1 redundancy as well. 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. feature allows provisioning a device with a configuration that contains the aaa authorization commands. Physically disconnect the failed box and send it for RMA, 2. To configure the switch port for PortFast, set the port to be connected as a host port, using the switch port host command or directly with the PortFast command. Given this information, the following should be considered when moving APs between two C9800 wireless controllers (C9800-1 and C9800-2): If the AP on C9800-1 doesnt hold any tag information (either via the ap tag persistency feature or via the command ap name write tag-config)and there is no mapping configured for that AP on C9800-2, the AP will be assigned default tags when moved to C9800-2.

As just described, with the C9800, some configurations are done differently than in AireOS, with the intent of making the settings more flexible and easier to use. Zone-based firewall, IPS/Snort, Public Key Infrastructure (PKI), ACL, trustworthy system, Challenge Handshake (CHAP) and Password Authentication (PAP),
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 The outdoor environment is a challenging RF environment. 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. This means that multiple wired devices with different IP addresses will be registered with the same MAC address, the one from the WGB itself. over SD-Access transit does not support broadcast packets. This allow the user to have the same 802.1X SSID configured for AAA override in one location (group of APs = policy tag) and not in another, if desired. It is recommended that you enable the broadcast SSID option to have the best client interoperability. The options in the Port Assignment tab for a fabric site have been enhanced. Depending on the regulatory domain, this can be from 4 to 12 additional channels. This release introduces APIs that help in developing customized workflows for fabric operations. Use multicast forwarding mode for the best performance with less bandwidth utilization for multicast applications when the underlying switched infrastructure supports multicast.

Choose DCA channels for higher performance, as the system will scan the least number of channels. blocks over 20 billion threats each day. In the Client Health Summary, the trend view of wireless clients is enhanced. How do you design your site tags? to Cisco vManage. The C9800 wireless controller does this using the air metrics reported by each radio on every possible channel and providing a solution that maximizes channel bandwidth and minimizes RF interference; interference is from all sources, such as self (signal), other networks (foreign Wi-Fi interference), and noise (everything else). For an AP in FlexConnect local switching mode: Using vlan-id 1, a client is assigned to the FlexConnect native VLAN. Supports 100G+ HW encryption for high-bandwidth secure L3 transport between sites or from cloud to site. available in the right pane of every online document. the Design > Network Settings > Wireless window. WebIntroduction Cisco has recently introduced NETCONF/YANG support across the enterprise network portfolio. Apart from this topology, you cannot cascade a mix If you are designing for a hotspot, enable the lowest data rate, because the goal is to have coverage gain versus speed. When you log in to the RabbitMQ management GUI and open the respective Copy and paste the certificate hash into the AireOS mobility peer configuration: Data link encryption (encrypting client data traffic between controllers) is optional and is recommended if the tunnel is built on top of a nontrusted network. Cisco AI Network Analytics: 6-GHz Radio Support. By default, when an AP joins the C9800 wireless controller, it will get the default tags, namely the default policy tag, default site tag, and default RF tag. assurance issues. In the migration design phase, when defining a common SSID for roaming, use a different VLAN ID and subnets on the Catalyst 9800 and on the AireOS WLC. In these cases its recommended that you disable CleanAir detection for these types of devices. Default: This is the default tag source. Secure Real-Time Transport Protocol (SRTP), Voice over Frame Relay (VoFR) (FRF.11)), VoIP, transcoding, V.150, MGCP. The command is below: key config-key password-encrypt password encryption aes. This mode uses more memory than install mode, since the packages extracted during bootup are copied to the RAM. On the CLI, use the show ap tag summary command: This command clearly indicates whether there is a misconfiguration involving tags and profiles. show logging profile sdwan .

Essential Metro, Carrier Ethernet, and Broadband Support. Cisco AI Network Analytics supports 6-GHz RF for the following functionalities: A new Radio Down issue is added to the AP issues. Make sure that the active WLC is configured with a higher chassis priority (= 2), 3. 5. When a user fails to authenticate, the controller can exclude the client. For example, if WebHook Threshold equals 2, you receive two notifications for that webhook URL per minute. To configure a Password policy, go to Configuration > Security > AAA and define a policy for your password: The user login policy allows you to limit the number of concurrent logins by different devices using the same user credentials. Notifications are messages that the device sends to the Cisco vManage server. To enable Dashboard session time out, click the settings (gear) icon on the top right corner of any page and toggle this setting: The latest releases include inline guided assistance to help customers with the GUI configuration. 80 MHz: Sets the channel width for the 802.11ac/ax radios to 80 MHz. Use the Events screen to display detailed information on events generated by Cisco SD-WAN devices. The interfaces on the device security policies. But in the case of a sudden change in the RF coveragefor example, if the AP fails or becomes disabledTPC can also increase the power of the surrounding APs. Note: This should be done in most scenarios, except for small Embedded Wireless Controller (EWC)-based network deployments, in which all devices (AP, WLC, clients) might be on the same VLAN. In the next popup window select Show Diff. This means that the user interface is the same and the features are the same. Provides operational status of every network device connected to Cisco

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. section for business-relevant application issues and
You must enter the preshared key (PSK) or shared secret for the AAA server as a part of the import flow. This applies to all the settings, and its a great value add. A maglev-registry failure occurs due to a TLS issue; unable to load the private key. A list of configured notifications is displayed in the table. Explore solutions; Cisco partners make the difference. Packet capture for analysis. The following table lists changes to this document since its initial release. Operations that take longer than 1 minute time out. In the C9800, it actually means no session timeout, so if you use the same setting as in AireOS, every roam will be a slow roam and require a full reauthentication. 802.11n can operate in a 40-MHz channel by bonding two 20-MHz channels together, which significantly increases throughput. To send email notifications when alarms occur: Click Alarm Notifications. dynamically to guarantee services, managed by Cisco DNA Center. It is also important not to re-use the same site tag across multiple Flex locations (this includes the default-site-tag). To show the defaults and change the EAPoL parameters, use the following GUI settings: RADIUS authentication and accounting servers should have 5 seconds as the minimum value for server timeout to prevent early expiration of the client authentication process during load. for a set of APs on the same site. To verify the CleanAir configuration on the different bands, do the following: CleanAir in general does not have an impact on network performance, and hence it should be left on. Lets analyze the recommendations one by one. The AP initially joined in the default site tag, which is by default a local site, and you can see that the AP is in local mode, as expected: Now assign the AP to the site tag created, the Flex-site one. This VLAN will be pushed to the APs: Using the VLAN name: In this case you create the VLAN name globally on the WLC first and then you must tell the AP which VLAN ID to use for that VLAN name at a specific site. Receive detailed reporting with full URL addresses, user and network identity and ability to allow or block actions, plus the external IP address. Any client assigned to this VLAN cant pass traffic or reach any network destination, with the goal of preventing a human configuration error and reducing the possibility of traffic leaks. Routers collect ACL logs every 10 minutes. Unable to delete the multiple devices table snmpgroupversionsettings. Monitor and re-direct traffic. Delete the current boot variable and set it to point to packages.conf. If you have devices that are still using Cisco Centralized Key Management, it is strongly recommended that you change CCKM validation to 5 seconds to avoid roaming issues when using Cisco based clients (such as 8821 IP phones or Cisco workgroup bridges). Consider the following guidelines before connecting the policy extended node-capable IE devices in a daisy chain: If a device and its onboarding node are at Cisco DNA Essentials license, the device is provisioned as an extended node. This option displays the status of the devices in the REP ring This can be in the context of APs migration or in a primary/secondary (N+1) high availability deployment. are incorrect for the client. Under Provision > Inventory > All Devices > Compliance > Summary, run a compliance check to compare the network profile with the current running configuration and see the summary. However, these IP address pools are not listed in the Host Onboarding window if the fabric site is defined at the building level. Traffic within the same VLAN is The Cisco vEdge router family is not compatible with Network Essentials and Network Advantage, and therefore
The client most likely looks at the top of the list for an AP on the same channel and then on the same band as one on which the client is currently operating. To view detailed information about a device on which an event was generated: The window displays events in both graphical and table format. Pushing configuration via CLI or GUI may not flash errors to the user if any of the settings are not applied correctly. This gives you the flexibility to decide which APs will get the settings and choose the appropriate values. Only unencrypted map archives can be imported. Before this release, events were shown only in the Device window. The list can be configured to focus on Dynamic Channel Assignment (DCA) channels (those channels that will be automatically assigned to APs) or to country channels (those valid only in the configured country), or to scan all possible channels. The recommendation is to assign all the APs in the same roaming domain (where seamless and fast roaming is needed) to the same site tag. To check the link SNR, use the following command: If you want to authenticate APs as they join the mesh network, an external RADIUS server should be configured for MAC authentications. Note: If the policy profile associated to the SSID is the same (same name and content) in different policy tags, then roaming for that SSID is seamless.
