Configuring IPv4 IMPB ARP Detection Configuration Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Step 9 Step 10 configure Enter global configuration mode. interface { fastEthernet port | range fastEthernet port-list | gigabitEthernet port | range gigabitEthernet port-list | ten-gigabitEthernet port | range ten-gigabitEthernet port-list } Enter interface configuration mode. ip arp inspection trust Configure the port as a trusted port, on which the ARP Detection function will not take effect. The specific ports, such as up-linked ports and routing ports are suggested to be set as trusted ports. ip arp inspection limit-rate value Specify the maximum number of the ARP packets can be received on the port per second. value: Specify the limit rate value. The valid values are from 0 to 300 pps (packets/second), and the default value is 100. ip arp inspection burst-interval value Specify a time range. If the speed of received ARP packets reaches the limit for this time range, the port will be shut down. value: Specify the time range. The valid values are from 1 to 15 seconds, and the default value is 1 second. show ip arp inspection interface View the configurations and status of the ports. show ip arp inspection vlan View the configurations and status of the VLANs. ip arp inspection recover (Optional) For ports on which the speed of receiving ARP packets has exceeded the limit, use this command to restore the port from Down status to Normal status. end Return to privileged EXEC mode. copy running-config startup-config Save the settings in the configuration file. The following example shows how to set port 1/02 as a trusted port, and set limit-rate as 20 pps and burst interval as 2 seconds on port 1/0/2: Switch#configure Switch(config)#interface gigabitEthernet 1/0/2 Switch(config-if)#ip arp inspection trust Switch(config-if)#ip arp inspection limit-rate 20 User Guide 744
