Example Configure the ports 1/0/2-5 as the Trusted Port: T1500-28PCT(config)#interface range fastEthernet 1/0/2-5 T1500-28PCT(config-if-range)#ip arp inspection trust 9.3 ip arp inspection(interface) Description The ip arp inspection command is used to enable the ARP Defend function. To disable the ARP detection function, please use no ip arp inspection command. ARP Attack flood produces lots of ARP Packets, which will occupy the bandwidth and slow the network speed extremely. With the ARP Defend enabled, the switch can terminate receiving the ARP packets for 300 seconds when the transmission speed of the legal ARP packet on the port exceeds the defined value so as to avoid ARP Attack flood.
