device(config-if-e1000-9/1/1)# broadcast limit 131072 kbps

The following example enables broadcast limit logging when the configured broadcast limit exceeds 100 Kbps.

device(config)# interface ethernet 1/2/1
device(config-if-e10000-1/2/1)# broadcast limit 100 kbps log

The following example sets the packet drop count threshold value to 2000 and specifies that the port shutodwn action is taken.

device(config)# interface ethernet 1/2/1
