ARP Packet
Validity Check
Select ARP packet validity check modes, including:
• Discard the ARP packet whose sender MAC address is different from the source MAC
address in the Ethernet header.
• Discard the ARP packet whose target MAC address is all 0s, all 1s, or inconsistent with
the destination MAC address in the Ethernet header.
• Discard the ARP request whose source IP address is all 0s, all 1s, or a multicast address,
and discard the ARP reply whose source and destination IP addresses are all 0s, all 1s,
or multicast addresses.
If none is selected, the system does not check the validity of ARP packets.
If both ARP packet validity check and user validity check are enabled, the former one
applies first, and then the latter applies.
