ip-address: IP address of the gateway.
Description
Use the arp filter source command to configure ARP packet filtering based on the gateway’s IP

packets from the host with the gateway’s IP address as the sender IP address are considered invalid
and discarded.
Use the undo arp filter source command to remove the configuration.
By default, ARP packet filtering based on the gateway’s IP address is disabled.
Note that:
z This command should be configured on a port directly connected to hosts.
z If you execute this command repeatedly, the last configured command takes effect.
