Cisco DNA Center does not support the AP Location field which many customers use to track the physical location of the AP inside the floor and building where it is installed. When attempting to add an edge device to a fabric, Cisco DNA Center might return the following error:. If the value is empty, additional text is displayed under the "Shared secret must not be empty" line. The shared secret is not displayed when empty, so it's unclear what the field is used for.

When the Shared Secret field contains a value, nothing is displayed. When you click Show to see if there is a value configured, nothing is displayed. If a value is already configured, there is no indicator. Under the My Profile and Settings window, a change to the first name does not take effect. When the Notification Center is enabled for License notification , Assurance issue notifications are reported along with the license notifications.

While there is no functional impact, notifications become a bit noisy based on the amount of network issues that Cisco DNA Center detects. Also, the Assurance issues don't provide any details when you click the notifications. In the Workflows GUI, when the text in an "In Progress" tile is long or impedes other elements in the tile, the text should be truncated or abbreviated. For example, the title of the following in-progress workflow is too long and should be truncated:.

Cisco DNA Center interactive wireless template is not applied to the wireless controller. Cisco DNA Center might fail to collect inventory from a wireless controller that has unassociated APs that are not deleted or moved to another wireless controller.

The Cisco DNA Center threadmanagermonitor table should be pruned periodically to keep the size of the database from growing too large. Cisco DNA Center fabric provisioning takes a long time when multiple sites are connected to the transit.

Cisco DNA Center might be unable to provision a managed device after an initial provision failure, instead citing the following error:. This causes subsequent LAN automation sessions to fail.

X, the bulk application upgrade downloads from the GUI fails with the warning, "Downloading packages ended with an error. Wireless controller provisioning is blocked when the RF profile is deleted from the Design window but not cleaned from the database.

There is a mismatch in the unassigned device count and what is seen in inventory after removal of the GPS marker. After fixing an authorization failure, AAA users are able to log in but cannot perform certain operations. The following error is returned:. Upgrading the Cisco DNA Center application packages fails due to a constraint violation on the lispcomponent table. The logs show the error "Null value was assigned to a property of primitive type setter of com.

When Cisco DNA Center is used to enabling application telemetry on a network device by tagging the desired LAN interfaces with the "lan" keyword in the interface description, Tunnel and Port-Channel interfaces do not get enabled.

Cisco DNA Center discovery fails to retrieve global credentials while trying to create a new task. Device is ready to be claimed. This causes a conflict in the actual configuration push to the device through Cisco DNA Center provisioning. After a failed wireless controller provisioning attempt, Cisco DNA Center might not roll back the configuration from the wireless controller, which might cause a network outage. When the kubelet certificate expires and is refreshed, the kubelet goes down and all services go down.

Reconfigure device provision might not determine configuration changes for the Dot1x Auth Template. The migration logs show a deadlock on the Postgres executionevent table. This issue stems from a large database table upon which database update queries pile up, causing a deadlock. If you are upgrading to Cisco DNA Center and all of the following conditions apply, the upgrade never starts:.

The version of Cisco ISE is not 2. Although the UI does not indicate that the upgrade failed to start, the logs contain messages related to the upgrade failure. To work around this problem, upgrade Cisco ISE to 2. You can only restore a backup to an appliance that is running the same Cisco DNA Center software version, applications, and application versions as the appliance and applications from which the backup was taken.

Choose Edit for the server. Enter your Cisco ISE password to update. After performing a restore operation, the configuration of devices in the network might not be in sync with the restored database.

In such a scenario, you should manually revert the CLI commands pushed for authentication, authorization, and accounting AAA and configuration on the network devices. Refer to the individual network device documentation for information about the CLI commands to enter. Re-enter the device credentials in the restored database.

If you updated the site-level credentials before the database restore, and the backup that is being restored does not have the credential change information, all the devices go to partial-collection after restore. 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. Perform AAA provisioning only after adjusting network device differential changes to the restored database.

Otherwise, device lockouts might occur. You can back up and restore Automation data only or both Automation and Assurance data. Full certificate chains must be uploaded to Cisco DNA Center while replacing an existing certificate.

Cisco DNA Center supports up to a maximum of 1. Fabric interfaces include physical and virtual interfaces like switched virtual interfaces, loopback interfaces, and so on. If the fabric site is defined at the building level, you must reserve the IP address pools at the building level; if the fabric site is defined at the area level, you must reserve the IP address pools at the area level.

To work around this issue, release and reserve the IP address pool at the same level area or building as the fabric site, or reconfigure the fabric site at the same level as the reserved IP address pool. In a fabric setup with Cisco Catalyst HA devices, if one of the HA devices goes down, you must complete the following steps to replace it:.

Cisco DNA Center shows the device as standalone; the standby has failed and has been removed. Set the priority for the devices. If you want the existing device to return as the active device after forming HA with the new device, ensure that the HA priority of the existing device is set to 2 or the highest available priority value. Alternatively, you can enter the following CLI command to configure the device priority:. To view the chassis number and the current priority value, enter the show chassis EXEC command.

If the priority is set to the default value of 1 on both devices, the device with the lower MAC address becomes the active device. Configure the chassis redundancy command on the new device using the same local and remote IP addresses that were used on the failed device. The Inventory window shows the new HA pair. Verify the serial numbers in the Serial Number column. For an HA pair, both the active and standby serial numbers are shown. Cisco DNA Center can learn only one wireless controller at a time.

For authentication and accounting servers, if the RADIUS server is present in the device, it is given first preference. The authentication and accounting servers must have the same IP addresses for them to be learned through brownfield provisioning. A wireless conflict is based only on the SSID name, and does not consider other attributes.

If an AP is migrated after a policy is created, you must manually edit the policy and point the policy to an appropriate AP location before deploying the policy. Otherwise, Policy Deployment failed is displayed. After the provisioning failure, the AP rejoins the wireless controller. You can reprovision the AP for a successful provisioning.

Provisioning of APs takes longer in this release as compared to 3 minutes in earlier releases. The interface or VLAN configuration is not differentiated between foreign and anchor controllers.

Rogue-on-wire detection is impacted; Cisco DNA Center does not show all clients connected to a switch via an access point in bridge mode. The trunk port is used to exchange all VLAN information. When you enable IP device tracking on the trunk port, clients connected on the neighbor switch are also shown. Cisco DNA Center does not collect client data if the connected interface is a trunk port and the neighbor is a switch.

As a best practice, disable IP device tracking on the trunk port. The rogue-on-wire is not detected if the IP device tracking is enabled on the trunk port. If the IPAM server is already configured, skip this step. You might see the following error if a CA-signed certificate is revoked by the certificate authority:. In the preceding example, the CN value is www.

Click Import and upload the new certificate. Most deployments recommend that VLAN 1 be disabled. Cisco Group-Based Policy Analytics supports up to five concurrent requests based on realistic customer data.

While it is desirable for GUI operations to respond within 5 seconds or less, for extreme cases based on realistic data, it can take up to 20 seconds. There is no mechanism to prevent more than five simultaneous requests at a time, but if it does happen, it might cause some GUI operations to fail. Operations that take longer than 1 minute will time out.

However, some time zones are at a minute or minute offset from UTC. If the Cisco DNA Center server is located in a time zone with a minute or minute offset from UTC and the client is located in a time zone with an hourly offset from UTC, or vice versa, the time ranges for data aggregation in Cisco Group-Based Policy Analytics are incorrect for the client.

IST, which corresponds to the time range - a. PDT in California, no aggregations are seen. Group changes that occur within an hour are not captured. When an endpoint changes from one scalable group to another, Cisco Group-Based Policy Analytics is unaware of this change until the next hour.

To force Cisco DNA Center to choose a specific interface, add netflow-source in the description of the interface. You can use a special character followed by a space after netflow-source , but not before it. For example, the following syntax is valid:. Use this link to open a TAC case.
