Command History
Usage Guidelines A cause (all, bpduguard and so forth) is defined as the reason that the error-disabled state occurred.
When a cause is detected on an interface, the interface is placed in error-disabled state, an operational
state similar to link-down state. If you do not enable errdisable recovery for the cause, the interface stays
in error-disabled state until you enter a shutdown and no shutdown interface configuration command.
If you enable the recovery for a cause, the interface is brought out of the error-disabled state and allowed
to retry the operation again when all the causes have timed out.
Otherwise, you must enter the shutdown then no shutdown commands to manually recover an interface
from the error-disabled state
Examples This example shows how to enable the recovery timer for the BPDU guard error-disabled cause:
Switch(config)# errdisable recovery cause bpduguard
This example shows how to set the timer to 500 seconds:
Switch(config)# errdisable recovery interval 500
You can verify your settings by entering the show errdisable recovery privileged EXEC command.
