MAC ACLs
– 350 –
The ethertype option can only be used to filter Ethernet II formatted packets.
A detailed listing of Ethernet protocol types can be found in RFC 1060. A few of
the more common types include the following:
0800 - IP
0806 - ARP
8137 - IPX
If an Extended IPv4 rule and MAC rule match the same packet, and these rules
specify a “permit” entry and “deny” entry, the “deny” action takes precedence.
Example
This rule permits packets from any source MAC address to the destination address
00-e0-29-94-34-de where the Ethernet type is 0800.
Console(config-mac-acl)#permit any host 00-e0-29-94-34-de ethertype 0800
Console(config-mac-acl)#
