Command History
Usage Guidelines This command prevents oscillations when revertive switching is configured for y-cable protected and
splitter protected configurations. If the preferred working signal is unstable, the wait-to-restore timer
prevents possible data loss that could result from frequent switchovers.
Caution Setting the wait-to-restore timer interval to 0 seconds disables the timer.
Note The default value for the wait-to-restore timer is sufficient for most network configurations.
Examples The following example shows how to modify the APS wait-to-restore timer.
Switch# configure terminal
Switch(config)# redundancy
Switch(config-red)# associate group newyork
Switch(config-red-aps)# aps disable
Switch(config-red-aps)# aps timer wait-to-restore 180
Switch(config-red-aps)# aps enable
seconds Specifies the number of seconds the system must wait before switching to
the preferred working signal. The range is 0 to 720 seconds.
