User Guidelines
Error disabled interfaces indicate that a problem occurred that must be
resolved by the administrator. This could be a configuration problem or a
physical problem (wiring) and does not necessarily indicate a problem with
the switch.
This command enables auto-recovery of an interface for the specified cause
(e.g., bpduguard) or all causes. An interface in the disabled state due to the
configured cause is recovered (link up) when the recovery interval expires. If
the interface continues to encounter errors (from any listed cause), it may be
placed back in the diag-disable state and the interface will be disabled (link
down).
Interfaces in the disabled state due to a listed cause may be manually
recovered by entering the no shutdown command for the interface.
