ON/N3000/N3100-ON/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 EMC Networking Auto
Recovery re-enables the interface after the expiry of configured time interval.
