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.

When a port is error-disabled, it is effectively shut down, and no traffic is sent or received on the port. For the
BPDU guard and port-security features, you can configure the switch to shut down just the offending
VLAN on the port when a violation occurs, instead of shutting down the entire port.

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.
