Command Mode
Interface Configuration Mode (interface fastEthernet / interface range
fastEthernet / interface gigabitEthernet / interface range gigabitEthernet /
interface ten-gigabitEthernet / interface range ten-gigabitEthernet)
Example
Configure the Gigabit Ethernet ports 1/0/2-5 as the Trusted Port:
T2700G-28TQ(config)#interface range
gigabitEthernet
1/0/2-5
T2700G-28TQ(config-if-range)#ip arp inspection trust
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.

Example
Enable the arp defend function for the Gigabit Ethernet ports 1/0/2-6:
T2700G-28TQ(config)#interface range gigabitEthernet
1/0/2-6
T2700G-28TQ(config-if-range)#ip arp inspection
