Layer 2 Switching Commands 541
When the interval expires, the system examines the error disabled interfaces
and recovers them if recovery for the indicated cause is enabled. Only a single
timer is used and recovery occurs when the timer expires, not when the
interface time expires. The recovery delay time indicates the number of
seconds until the interface is eligible for recovery if auto-recovery is enabled
for the indicated cause.
Interfaces recovered by auto-recovery issue a log message indicating that
recovery is being attempted.
