Configure the ports 2-5 as the Trusted Port:

TL-SG5428(config)# interface range gigabitEthernet 1/0/2-5

TL-SG5428(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.
