Configuring the Switchover-Enable Timer
The switchover-enable timer on the Cisco ONS 15530 prevents any automatic switchover from the
protection path to the working path until it has expired. When it expires, switchovers occur only if there
is no fault on the working path and there is no overriding switchover request in effect.
To configure the switchover-enable timer, use the following commands, beginning in global
configuration mode:
Command Purpose
Step 1
Switch(config)# redundancy
Switch(config-red)#
Enters redundancy configuration mode.
Step 2
Switch(config-red)# associate group name
Switch(config-red-aps)#
Selects the interfaces to associate and enters APS
configuration mode.
Note The group name is case sensitive.
Step 3
Switch(config-red-aps)# aps disable Disables the APS group.
Step 4
Switch(config-red-aps)# aps timer
switchover-enable min-interval seconds
Modifies the timer that controls the check on the
status of the working path. The default is 2 seconds.
Step 5
Switch(config-red-aps)# aps enable Enables the APS group.
