Command Usage
◆ New rules are added to the end of the list.
◆ 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)#
