Controllers
This section shows the number of controllers that are active in each management state. A
controller may be active in more than one state at the same time. For example, a controller
may be both Detected and Synchronized. Select the state name to display information
about all controllers in that state.
Configured: These controllers are configured as part of the team.
Synchronized: These controllers had their software and configuration settings
successfully updated by the team manager and are fully operational.
Unsynchronized: This can occur if the primary manager becomes non-functional during
the synchronization process leaving one or more team members with partially updated
configurations. When the interim manager takes over, it cannot update these controllers.
Therefore, the solution is to promote the interim manager to become the primary
manager. It can fully synchronize the configuration settings on all controllers.
Pending: An action is in progress. For example, firmware or configuration may be
uploading to the controller or the controller is restarting.
Unresponding: These controllers have stopped sending management information to the
manager. Rediscovery may re-establish the connection. If not, a network failure may have
occurred or the controllers may be inoperative.
Unauthorized: These controllers have not yet been authorized to join the team.
Authorization must be performed manually by an administrator by selecting Controllers
>> Overview > Discovered controllers and then selecting Authorize in the Action
column.
Unconfigurable: These controllers cannot be added because the team already has the
maximum number of supported members. To add these controllers you must first remove
one or more team members by selecting Controllers >> Overview > Team members,
then selecting the name of the controller you want to delete and then selecting Delete.
Detected: These controllers have sent a discovery request to the team manager and the
team manager has replied.
Configured: These controllers are members of the team. They may have been
automatically discovered or manually added.
Controlled APs
This section lists the number of controlled APs discovered by the team. APs are grouped
according to their management state. For a complete description of all management states,
see Monitoring the discovery process on page 6-13.
