errdisable detect cause
Usage Guidelines A cause (dhcp-rate-limit, dtp-flap, and so forth) is defined as the reason why the error-disabled state
occurred. When a cause is detected on an interface, the interface is placed in error-disabled state, an
operational state similar to link-down state.
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 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.
