ARP ACLs are configured with the commands described on

page 310

If static mode is enabled, the switch compares ARP packets to the

specified ARP ACLs. Packets matching an IP-to-MAC address binding in

a permit or deny rule are processed accordingly. Packets not matching

any of the ACL rules are dropped. Address bindings in the DHCP

snooping database are not checked.

If static mode is not enabled, packets are first validated against the

specified ARP ACL. Packets matching a deny rule are dropped. All

remaining packets are validated against the address bindings in the

DHCP snooping database.
