Creating Named MAC Extended ACLs
For more information about the supported non-IP protocols in the mac access-list extended command,
see the command reference for this release.
Though visible in the command-line help strings, appletalk is not supported as a matching condition for
Note
the deny and permit MAC access-list configuration mode commands.
Beginning in privileged EXEC mode, follow these steps to create a named MAC extended ACL:
Command
Step 1 configure terminal
Step 2
mac access-list extended name
Step 3 {deny | permit} {any | host source MAC
address | source MAC address mask} {any |
host destination MAC address | destination
MAC address mask} [type mask | lsap lsap mask
| aarp | amber | dec-spanning | decnet-iv |
diagnostic | dsm | etype-6000 | etype-8042 | lat
| lavc-sca | mop-console | mop-dump | msdos |
mumps | netbios | vines-echo |vines-ip |
xns-idp | 0-65535] [cos cos]
Step 4 end
Step 5 show access-lists [number | name]
Step 6
copy running-config startup-config
Use the no mac access-list extended name global configuration command to delete the entire ACL. You
can also delete individual ACEs from named MAC extended ACLs.
This example shows how to create and display an access list named mac1, denying only EtherType
DECnet Phase IV traffic, but permitting all other types of traffic.
Switch(config)# mac access-list extended mac1
Switch(config-ext-macl)# deny any any decnet-iv
Switch(config-ext-macl)# permit any any
Switch(config-ext-macl)# end
Switch # show access-lists
Extended MAC access list mac1

Purpose
Enter global configuration mode.
Define an extended MAC access list using a name.
In extended MAC access-list configuration mode, specify to
permit or deny any source MAC address, a source MAC address
with a mask, or a specific host source MAC address and any
destination MAC address, destination MAC address with a mask,
or a specific destination MAC address.
(Optional) You can also enter these options:
type mask—An arbitrary EtherType number of a packet with
•
Ethernet II or SNAP encapsulation in decimal, hexadecimal,
or octal with optional mask of don't care bits applied to the
EtherType before testing for a match.
• lsap lsap mask—An LSAP number of a packet with
IEEE 802.2 encapsulation in decimal, hexadecimal, or octal
with optional mask of don't care bits.

| xns-idp—A non-IP protocol.
cos cos—An IEEE 802.1Q cost of service number from 0 to 7

used to set priority.
Return to privileged EXEC mode.
Show the access list configuration.
