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 the error-disabled state, an operational
state similar to link-down state. If you do not enable the recovery for the cause, the interface stays in the
error-disabled state until you enter the
shutdown
and the
no shutdown
interface configuration
commands. 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
and then the
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.
