Configuring ARP detection based on specified objects
With this feature configured, the device permits the ARP packets received from an ARP trusted port and
checks the ARP packets received from an ARP untrusted port. You can specify objects in the ARP packets
to be checked by using the following options:
• src-mac—Checks whether the sender MAC address of an ARP packet 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 in an ARP packet. Any all-zero, all-one or multicast
IP addresses are considered invalid, and the corresponding packets are discarded. With this object
specified, the sender and target IP addresses of ARP replies and the source IP address of ARP
requests are checked.
