Usage Guidelines
A cause (bpduguard, dtp-flap, link-flap, pagp-flap, udld) is defined as the reason why the error-disabled
state occurred. When a cause is detected on an interface, the interface is placed in error-disabled state
(an operational state that is similar to the link-down state). If you do not enable error-disable recovery
for the cause, the interface stays in the error-disabled state until a shutdown and no shutdown occurs. If
you enable recovery for a cause, the interface is brought out of the error-disabled state and allowed to
retry operation again once all the causes have timed out.
You must enter the shutdown command and then the no shutdown command to recover an interface
manually from error disable.
