Parameters
dst-mac: Checks the target MAC address of ARP responses. 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 source and destination IP addresses of ARP packets. The all-zero, all-one, or
multicast IP addresses are considered invalid and the corresponding packets are discarded. With
this keyword specified, the source and destination IP addresses of ARP replies, and the source IP
address of ARP requests are checked.
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 considered valid. Otherwise, the
packet is discarded.
Examples
# Enable ARP packet validity check by checking the MAC addresses and IP addresses of ARP
packets.
