Instructions to activate HA on Catalyst Center.

Catalyst Center's implementation of HA is described in the Cisco Catalyst Center High Availability Guide. We recommend that you first review this information and then determine whether you want to deploy HA in your production environment. If you choose to do so, complete the following steps:

  1. From the main menu, choose System > Settings > System Configuration > High Availability.

  2. Click Activate High Availability.

After you click Activate High Availability, Catalyst Center enters into maintenance mode. In this mode, Catalyst Center is unavailable until the redistribution of services is completed. You must take this into account when scheduling an HA deployment.

Note

Catalyst Center goes into maintenance mode every time you restore the database, perform a system upgrade (not a package upgrade), and activate HA (as described above).
