Using the GUI to Configure Backup Controllers

Step 2 From the Local Mode AP Fast Heartbeat Timer State drop-down box, choose Enable to enable the fast heartbeat timer for access points in local mode or Disable to disable this timer. The default value is Disable.

Step 3 If you chose Enable in Step 2, enter a number between 1 and 10 seconds (inclusive) in the Local Mode AP Fast Heartbeat Timeout field to configure the fast heartbeat timer for access points in local mode. Specifying a small heartbeat interval reduces the amount of time it takes to detect a controller failure. The default value is 0 seconds, which disables the timer.

Step 4 From the H-REAP Mode AP Fast Heartbeat Timer State drop-down box, choose Enable to enable the fast heartbeat timer for hybrid-REAP access points or Disable to disable this timer. The default value is Disable.

Step 5 If you chose Enable in Step 4, enter a value between 1 and 10 seconds (inclusive) in the H-REAP Mode AP Fast Heartbeat Timeout field to configure the fast heartbeat timer for hybrid-REAP access points. Specifying a small heartbeat interval reduces the amount of time it takes to detect a controller failure. The default value is 0 seconds, which disables the timer.

Step 6 In the AP Primary Discovery Timeout field, a value between 30 and 3600 seconds (inclusive) to configure the access point primary discovery request timer. The default value is 120 seconds.
