Usage Guideline
This command takes effect for both trusted and un-trusted interfaces. When the rate of the ARP packet
per second exceeds the limitation and the condition sustained for the configured burst duration, the port
will be put in the error disable state.
Example
This example shows how to limit the rate of the incoming ARP requests to 30 packets per second and to
set the interface monitoring interval to 5 consecutive seconds.
Switch# configure terminal
Switch(config)# interface eth3/0/10
Switch(config-if)# ip arp inspection limit rate 30 burst interval 5
Switch(config-if)#
