• src-mac—Checks whether the sender MAC address in the message body is identical to the source
MAC address in the Ethernet header. If they are identical, the packet is forwarded. Otherwise, the
packet is discarded.
• dst-mac—Checks the target MAC address of ARP replies. If the target MAC address is all-zero,
all-one, or inconsistent with the destination MAC address in the Ethernet header, the packet is
considered invalid and discarded.
• ip—Checks the sender and target IP addresses of ARP replies, and the sender IP address of ARP
requests. All-zero, all-one, or multicast IP addresses are considered invalid and the corresponding
packets are discarded.

The port is an untrusted port
by default.
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.
