Viewing Wireless AP Availability

In session availability, the Wireless Availability report displays the state of both the tunnels — active tunnel and backup tunnel — on both the primary and secondary wireless controllers.

The report uses a Color Legend to indicate the tunnel state:

• Green — AP has established an active tunnel.
• Blue — AP has established a backup tunnel.
• Red — AP is not connected.

In the report, each AP is represented by a box.

• The label, Foreign or Local, indicates whether the AP is local or foreign on the controller.
• The color in the upper pane of the box represents the state of the tunnel that is established to the current controller.
  

  Note

  The current controller is the one on which the AP Availability report is viewed.
• The color in the lower pane of the box represents the state of the tunnel that is established with the other controller.

For the ease of understanding, take the example of the following scenario:

• Controller1 and Controller2 are paired in session availability
• A Wireless AP has established an active tunnel to Controller1.
• The same AP has established a backup tunnel to Controller2.

If you open the Wireless AP Availability report on Controller2, the report will appear as follows:

In the above example, the circled AP has established a backup tunnel to the foreign (secondary) controller, and an active tunnel to the local (Primary) controller.
