After configuring the ARP GUARD address, the ARP messages received from the ports configured

GUARD address configured on this port, these messages will be judged as ARP cheating

messages, which will be directly dropped instead of sending to the CPU of the switch or forwarding.

16 ARP GUARD addresses can be configured on each port.

Example:

Configure the ARP GUARD address on port ethernet1/1 as 100.1.1.1.

switch(config)#interface ethernet1/1

switch(Config-If-Ethernet 1/1)#arp-guard ip 100.1.1.1

Delete the ARP GUARD address on port ethernet1/1 as 100.1.1.1.

switch(config)#interface ethernet1/1

switch(Config-If-Ethernet 1/1)#no arp-guard ip 100.1.1.1
