ip arp inspection limit
On stacking-capable switches, the rate limit is calculated separately on each switch in a switch stack.
For a cross-stack EtherChannel, this means that the actual rate limit might be higher than the configured
value. For example, if you set the rate limit to 30 pps on an EtherChannel that has one port on switch 1
and one port on switch 2, each port can receive packets at 29 pps without causing the EtherChannel to
become error-disabled.
The rate of incoming ARP packets on EtherChannel ports equals the sum of the incoming rate of ARP
packets from all the channel members. Configure the rate limit for EtherChannel ports only after
examining the rate of incoming ARP packets on all the channel members.
Examples This example shows how to limit the rate of incoming ARP requests on a port to 25 pps and to set the
interface monitoring interval to 5 consecutive seconds:
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# ip arp inspection limit rate 25 burst interval 5
You can verify your settings by entering the show ip arp inspection interfaces interface-id privileged
EXEC command.
