NSPECTION
Use the Static ARP Inspection Table to bind a static address to a port. Table
entries include a port identifier, VLAN identifier, source MAC address in ARP
request packets, and source IP address in ARP request packets.
ARP Inspection uses the DHCP snooping bindings database for the list of
valid IP-to-MAC address bindings. Static ARP entries take precedence over
entries in the DHCP snooping bindings database. The switch first compares
ARP packets to any entries specified in the static ARP table. If no static
entry matches the packets, then the DHCP snooping bindings database
determines their validity.
