Interface Error Disable and Auto

Recovery

Dell Networking N1500/N2000/N3000/N4000 Series Switches

Interface error disable automatically disables an interface when an error is

detected; no traffic is allowed until the interface is either manually re-enabled

or, if auto recovery is configured, the configured auto recovery time interval

has passed.

For interface error disable and auto recovery, when an error condition is

detected for an interface, the interface is placed in a diagnostic disabled state

by shutting down the interface. The error disabled interface does not allow

any traffic until the interface is re-enabled. The error disabled interface can

be manually enabled using the no shutdown command. Alternatively

administrator can enable auto recovery feature. Dell Networking Auto

Recovery re-enables the interface after the expiry of configured time interval.
