User Guidelines
Error disabled interfaces indicate that a problem that must be resolved by the
administrator. This could be a configuration problem or a physical problem
and does not necessarily indicate a problem with the switch.
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.
Interfaces recovered by auto-recovery issue a log message indicating that
recovery is being attempted.
