Usage Guidelines
In a VLAN access map, if at least one ACL is configured for a packet type (IP or MAC), the default
action for the packet type is drop (deny).
If an ACL is not configured for a packet type, the default action for the packet type is forward (permit).
If an ACL for a packet type is configured and the ACL is empty or undefined, the configured action will
be applied to the packet type.
