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.
