◆
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.
