Configure MAC Extended ACL

MAC extended ACL can make the classification rule according to the Ethernet protocol type, source MAC address, destination MAC address, VLAN ID, and 802.1p priority, so as to filter the packets.

Configuration Condition

None

Configure MAC Extended ACL

MAC extended ACL name can use the number and also can use the customized character string. If the MAC extended ACL name adopts the numbers, we can configure the maximum quantity limitation of ACL; if adopting the customized character string, there is no limitation for the maximum quantity of ACL. The user can select the ACL name as desired. MAC extended ACL is richer, more correct, and more flexible than the contents defined by MAC standard ACL.

Description

Enter global configuration mode

Configure the MAC extended ACL

mac access-list extended { access-list-number | access-list-name }

Mandatory

By default, MAC extended ACL is not configured.

The sequence range of the MAC extended ACL is 3001-4000.

Configure the permit rule of ACL

[ sequence ] permit { any | source-addr source-wildcard | host source-addr } { any | destination-addr destination-wildcard | host destination-addr } [ ether-type type ] [ cos cos ] [ vlan-id vlan ] [ time-range time-range-name ] [log] [ l2-action-group l2-action-group-name ] [ egr-action-group egr-action-group-name ] [ vfp-action-group vfp-action-group-name ]

Optional

By default, the permit rule of ACL is not configured.

Configure the refuse rule of ACL

[ sequence ] deny { any | source-addr source-wildcard | host source-addr } { any | destination-addr destination-wildcard | host destination-addr } [ ether-type type ] [ cos cos ] [ vlan-id vlan ] [ time-range time-range-name ] [log] [ l2-action-group l2-action-group-name ] [ egr-action-group egr-action-group-name ] [ vfp-action-group vfp-action-group-name ]

Optional

By default, the refuse rule of ACL is not configured.

Configure the ACL remarks

[ sequence ] remark comment

Optional

By default, the remarks of ACL are not configured.

note


  • When using the mac access-list extended command to create the MAC extended ACL, the ACL can be created only after configuring the rules in the MAC extended ACL configuration mode.
  • Sequence means the order number of the rule in the ACL. ACL matches and filters the packet strictly according to the order from small sequence to large sequence. The rule with the small sequence first takes effect. When all rules do not match, execute the default drop action, that is, all the packets not permitted to pass are dropped.

Configure MAC Extended ACL Named by Numbers

The MAC extended ACL named by numbers can let the user identify the type of the ACL quickly. However, the MAC extended ACL named by numbers has some limitations. For example, the ACL quantity is limited. MAC extended ACL is richer, more correct, and more flexible than the contents defined by MAC standard ACL.
