Creating Layer 2 Mac Acls - Cisco ME 3400 Software Configuration Manual

Command

Step 4

Step 5 copy running-config startup-config
To delete an access list, use the no access-list access-list-number global configuration command.
This example shows how to create an ACL that permits IP traffic from any source to any destination that
has the DSCP value set to 32:
Switch(config)# access-list 100 permit ip any any dscp 32
This example shows how to create an ACL that permits IP traffic from a source host at 10.1.1.1 to a
destination host at 10.1.1.2 with a precedence value of 5:
Switch(config)# access-list 100 permit ip host 10.1.1.1 host 10.1.1.2 precedence 5

Creating Layer 2 MAC ACLs

Beginning in privileged EXEC mode, follow these steps to create a Layer 2 MAC ACL for non-IP traffic:
Command
Step 1
configure terminal
Step 2 mac access-list extended name
Step 3 permit {host src-MAC-addr mask | any |
host dst-MAC-addr | dst-MAC-addr
mask} [type mask]
Step 4 end
Step 5
show access-lists [access-list-number |
access-list-name]
Step 6
copy running-config startup-config
To delete an access list, use the no mac access-list extended access-list-name global configuration
command.

Purpose
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Create a Layer 2 MAC ACL by specifying the name of the list and enter
extended MAC ACL configuration mode.
Always use the permit keyword for ACLs used as match criteria in QoS
policies.
For src-MAC-addr, enter the MAC address of the host from which the
•
packet is being sent. You can specify in hexadecimal format (H.H.H),
use the any keyword for source 0.0.0, source-wildcard ffff.ffff.ffff, or
use the host keyword for source 0.0.0.
For mask, enter the wildcard bits by placing ones in the bit positions
•
that you want to ignore.
For dst-MAC-addr, enter the MAC address of the host to which the
•
packet is being sent. You can specify in hexadecimal format (H.H.H),
use the any keyword for source 0.0.0, source-wildcard ffff.ffff.ffff, or
use the host keyword for source 0.0.0.
(Optional) For type mask, specify the Ethertype number of a packet
•
with Ethernet II or SNAP encapsulation to identify the protocol of
the packet. For type, the range is from 0 to 65535, typically specified
in hexadecimal. For mask, enter the don't care bits applied to the
Ethertype before testing for a match.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
