Adds an EtherType ACE.
The access_list_name argument lists the name or number of an ACL. When you specify an ACL name, the ACE is added to the end of the ACL. Enter the access_list_name in upper case letters so that the name is easy to see in the configuration. You might want to name the ACL for the interface (for example, INSIDE) or for the purpose (for example, MPLS or PIX).
The permit keyword permits access if the conditions are matched. deny denies access.
The ipx keyword specifies access to IPX.
The bpdu keyword specifies access to bridge protocol data units, which are allowed by default.
The deny keyword denies access if the conditions are matched. If an EtherType ACL is configured to deny all, all ethernet frames are discarded. Only physical protocol traffic, such as auto-negotiation, is still allowed.
The mpls-multicast keyword specifies access to MPLS multicast.
The mpls-unicast keyword specifies access to MPLS unicast.
The is-is keyword specifies access to IS-IS traffic.
The any keyword specifies access to any traffic.
The hex_number argument indicates any EtherType that can be identified by a 16-bit hexadecimal number greater than or equal to 0x600. (See RFC 1700, “Assigned Numbers,” at http://www.ietf.org/rfc/rfc1700.txt for a list of EtherTypes.)
Note To remove an EtherType ACE, enter the no access-list command with the entire command syntax string as it appears in the configuration.
