A port is automatically placed in a any of the following error state by the switch because of an error condition that is encountered on the port.
Drop

Based on the configuration the traffic can be either Dropped , Logged or the port can be Shutdown and When a port is in error state Shutdown, it is effectively shut down and no traffic is sent or received on that port. You can apply auto-recovery-time option only if the action is shutdownThe port can be reactivated after the configured time by configuring the auto-recovery option or can be recovered manually.
Environment: This articles applies to Aruba Mobility Access Switches running AOS version 7.1.3.0 and above.
Viewing Port ErrorsUse the following command to view the list of ports that are detected with port errors and the time at which they willbe recovered automatically, if auto-recovery is enabled:(host) #show port-error-recoveryLayer-2 Interface Error Information-----------------------------------Interface Error Recovery Time--------- ----- -------------Pc5 Shutdown (Loop Detected) 2012-02-08 16:42:45 (PST)GE0/0/42 Shutdown (Loop Detected) No Auto recoveryPc1 Shutdown (Loop Detected) 2012-02-07 16:45:40 (PST)Pc2 Shutdown (RA Guard) 2012-02-08 16:42:45 (PST)GE0/0/14 Log (Mac Limit Exceeded) No Auto recoveryGE0/0/2 Drop (DHCP Trust Error) 2012-02-07 16:45:40 (PST)GE0/0/5 Log (MAC Limit exceed) No Auto recoveryGE1/0/24 Shutdown (BPDU received) 2012-10-18 11:25:17 (PST)Recovering Ports ManuallyUse the CLI to manually recover the port errors. To recover the ports on a specific interface execute the following command:host) #clear port-error-recovery interface <interface-name>The following command clears the errors on gigabitethernet 0/0/42:(host) #clear port-error-recovery interface gigabitethernet 0/0/42To clear the port errors on all interfaces execute the following command:(host) #clear port-error-recoveryNote :- The maximum value for auto-recovery-time for all the port security functionalities is 65535 seconds.
