threshold (it is defaulted to be 300 packet/second), disable this interface and send trap of

interface being abnormal. After a certain time (it is defaulted to be 480 seconds), re-enable the

interface. If this interface will not be re-disabled by interface CAR in 2 seconds, the storm of

2 seconds, no trap of interface being abnormal is sent.
