Creating Layer 2 Mac Acls - Cisco IE-4000 Software Configuration Manual

Configuring QoS
Configuring QoS
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
1. configure terminal
2. mac access-list extended name
3. permit {host src-MAC-addr mask | any
| host dst-MAC-addr | dst-MAC-addr
mask} [type mask]
4. end
5. show access-lists [access-list-number
| access-list-name]
6. copy running-config startup-config
To delete an access list, use the no mac access-list extended access-list-name global configuration command.
This example shows how to create a Layer 2 MAC ACL with two permit statements. The first statement allows traffic
from the host with MAC address 0001.0000.0001 to the host with MAC address 0002.0000.0001. The second statement
allows only Ethertype XNS-IDP traffic from the host with MAC address 0001.0000.0002 to the host with MAC address
0002.0000.0002.
Switch(config)# mac access-list extended maclist1
Switch(config-ext-macl)# permit 0001.0000.0001 0.0.0 0002.0000.0001 0.0.0
Switch(config-ext-macl)# permit 0001.0000.0002 0.0.0 0002.0000.0002 0.0.0 xns-idp
Switch(config-ext-macl)# exit
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.
