errdisable detect cause
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 set a recovery mechanism for the cause by entering the errdisable recovery global configuration
command for the cause, the interface is brought out of the error-disabled state and allowed to retry the
operation when all causes have timed out. If you do not set a recovery mechanism, you must enter the
shutdown and then the no shutdown commands to manually recover an interface from the
error-disabled state.
You can verify your setting by entering the show errdisable detect privileged EXEC command.
Examples This example shows how to enable error-disabled detection for the link-flap error-disabled cause:
Switch(config)# errdisable detect cause link-flap
