Port Auto Recovery Configuration Fields

Field Description
Auto Recovery Components This field lists all the components that support the Auto Recovery feature. For each component, you can enable or disable Auto Recovery.

An interface in the diagnostic disabled state for the configured components is recovered (link up) when the recovery interval expires. If the interface continues to encounter errors (from any listed components), it may be placed back in the diagnostic disabled state, and the interface will be disabled (link down). Interfaces in the diagnostic disabled state may also be manually recovered by enabling them from the Port Summary page.

Auto Recovery is available for the following components:

  • ARP Inspection
  • BPDU Guard
  • BPDU Rate Limit
  • Broadcast Storm Control
  • Denial Of Service
  • DHCP (Dynamic Host Configuration Protocol) Rate Limit
  • Keepalive
  • MAC Locking
  • Multicast Storm Control
  • UDLD
  • Unicast Storm Control
Recovery Time The auto recovery time interval. The auto recovery time interval is common for all components. The default value of the timer is 300 seconds and the range is from 30 to 86400.
D-Disabled Interface Status This table displays the list of interfaces that are error disabled.
Interface The interface which is error disabled.
Admin Mode The administrative mode of the interface.
Port Status Whether the link is up or down. The link is the physical connection between the port or trunk and the interface on another device.
Error Disable Reason If the device detects an error condition for an interface, then the device puts the interface in error disabled state by placing the interface in diagnostic disabled state. The interface can go into error disable state for one of the following reasons:
  • ARP Inspection
  • BPDU Guard
  • BPDU Storm
  • Broadcast Storm
  • Denial Of Service
  • DHCP Rate Limit
  • Keepalive
  • MAC Locking
  • Multicast Storm
  • UDLD
  • Unicast Storm
Auto Recovery Time Left When Auto Recovery is enabled and the interface is placed in diagnostic disabled state, then a recovery timer starts for that interface. Once this timer expires, the device checks if the interface is in diagnostic disabled state. If yes, then the device enables the diagnostic disabled interface.
