Configuring ARP restricted forwarding
ARP restricted forwarding controls the forwarding of ARP packets that are received on untrusted ports and have passed ARP detection in the following cases:
If the packets are ARP requests, they are forwarded through the trusted ports.
If the packets are ARP responses, they are forwarded according to their destination MAC address. If no match is found in the MAC address table, they are forwarded through the trusted ports.
Before performing the following configuration, make sure you have configured the arp detection enable command.
