The Auto Recovery feature can automatically enable a disabled interface when the error conditions that caused the interface to be disabled are no longer detected. If Auto Recovery is not used (disabled), the interface remains disabled until an administrator manually enables it.
The switch supports an interface error disable feature that allows an interface to be automatically placed into a diagnostically disabled state when certain error conditions are detected on that interface. When an interface has been placed in a diagnostically disabled state, the interface is shut down, and no traffic is sent or received on that interface until it is either manually enabled by the administrator or re-enabled by the Auto Recovery feature after the recovery time interval has expired.
If the interface continues to encounter errors, it may be placed back into the diagnostically disabled state, and the interface will be disabled (link down). An interface in the diagnostically disabled state may also be manually recovered by enabling it from the Port Status page
