Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands
You should configure trunk ports with higher rates to reflect their aggregation. When the rate of
incoming packets exceeds the user-configured rate, the switch places the interface into an error-disabled
state. The error-disable recovery feature automatically removes the port from the error-disabled state
according to the recovery setting.
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.
