Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands

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.

Examples This example shows how to enable error-disabled detection for the link-flap error-disabled cause:

Switch(config)# errdisable detect cause link-flap

You can verify your setting by entering the show errdisable detect privileged EXEC command.
