errdisable detect cause

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.

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

Switch(config)# errdisable detect cause link-flap

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