Command History
Usage Guidelines Use this command to configure APS signal switchover lockout on the protection path. This is useful
when you want to prevent a switchover during shelf maintenance, or when the protection signal has
degraded or failed.
A lockout only succeeds when the protection path interface is also acting as the standby interface. If the
protection path interface is the active interface, use the aps switch command to switch the active
interface role back to the working interface.
Note The APS lockout does not persist across system reloads or CPU switch module switchovers.
Examples The following example shows how to lock out switchover to the protection path on an associated group
named group1.
Switch# aps lockout group1
