An EtherType ACL consists of one or more Access Control Entries (ACEs) specifying an EtherType. The EtherType rule controls the EtherType that can be identified by a 16-bit hexadecimal number and other traffic types.
Only non-IP layer-2 traffic is subject to the EtherType ACL, and this applies only to bridge group member interfaces. These rules can be used for traffic control (permit/drop) based on the EtherType value contained in the layer-2 packet.
