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.
vmps Enable the timer to recover from the VLAN Membership Policy Server
(VMPS) error-disabled state.
interval interval Specify the time to recover from the specified error-disabled state. The range
is 30 to 86400 seconds. The same interval is applied to all causes. The default
interval is 300 seconds.
Note The error-disabled recovery timer is initialized at a random
differential from the configured interval value. The difference
between the actual timeout value and the configured value can be up
to 15 percent of the configured interval.
