Command Attributes

•Action – An ACL can contain any combination of permit or deny rules.

•Source/Destination Address Type – Use “Any” to include all possible addresses, “Host” to indicate a specific MAC address, or “MAC” to specify an address range with the Address and Bitmask fields. (Options: Any, Host, MAC; Default: Any)

•Source/Destination MAC Address – Source or destination MAC address.

•Source/Destination Bitmask – Hexadecimal mask for source or destination MAC address.

•VID – VLAN ID. (Range: 1-4094)

•VID Mask – VLAN bitmask. (Range: 1-4094)

•Ethernet Type – This option can only be used to filter Ethernet II formatted packets. (Range: 600-fff hex.)

A detailed listing of Ethernet protocol types can be found in RFC 1060. A few of the more common types include 0800 (IP), 0806 (ARP), 8137 (IPX).

Command Usage

Egress MAC ACLs only work for destination-mac-known packets, not for multicast, broadcast, or destination-mac-unknown packets.

Web – Specify the action (i.e., Permit or Deny). Specify the source and/or destination addresses. Select the address type (Any, Host, or MAC). If you select “Host,” enter a specific address (e.g., 11-22-33-44-55-66). If you select “MAC,” enter a base address and a hexadecimal bitmask for an address range. Set any other required criteria, such as VID, Ethernet type, or packet format. Then click Add.
