NOTE
If the value of vlan vlan-id is specified, it indicates that VLAN-based traffic filtering is
configured and the traffic matching an ACL rule is filtered on all interfaces on the VLAN.
If the value of vlan vlan-id is not specified, it indicates that the statistics on the traffic matching
an ACL rule are collected on all interfaces of the device.
When the traffic-remark command and the traffic-filter (interface view) or traffic-filter
(system view) command are used simultaneously, and the same ACL rule is associated:
l If the deny action is configured in the ACL rule, the traffic-remark command does not
take effect.
l If the permit action is configured in the ACL rule, the traffic-remark command takes
effect.
A Layer 2 ACL and a Layer 3 ACL can be set in the traffic-remark command simultaneously.
The Layer 3 ACL and its rules can be configured only after the Layer 2 ACL and its rules are
configured. The Layer 2 ACL number ranges from 4000 to 4999 and the Layer 3 ACL number
ranges from 2000 to 2999 or 3000 to 3999.
To configure both Layer 2 ACLs and Layer 3 ACLs on an inbound interface of a switch, use
the following command:
traffic-remark [ vlan vlan-id ] inbound acl { l2-acl | name acl-name } [ rule rule-id ] acl
{ bas-acl | adv-acl | name acl-name } [ rule rule-id ] { 8021p 8021p-value | destination-
mac mac-address | dscp { dscp-name | dscp-value } | local-precedence local-precedence-
value | ip-precedence ip-precedence-value | vlan-id vlan-id }
If you use the traffic-remark vlan vlan-id inbound acl acl-number vlan vlan-id command
to re-mark VLAN IDs on incoming packets, the VLAN IDs must also be re-marked on outgoing
packets, for example:
traffic-remark vlan vlan-id1 inbound acl acl-number vlan vlan-id2
traffic-remark vlan vlan-id2 inbound acl acl-number vlan vlan-id1
Configuring re-marking on an interface
1.
Run:
system-view
The system view is displayed.
2.
Run:
interface interface-type interface-number
The interface view is displayed.
Or, run:
interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
3.
Run:
traffic-remark inbound acl { [ ipv6 ] { bas-acl | adv-acl | name acl-
name } | l2-acl | user-acl } [ rule rule-id ] { 8021p 8021p-value |
destination-mac mac-address |
precedence local-precedence-value | ip-precedence ip-precedence-value |
vlan-id vlan-id }
The priorities of incoming packets matching an ACL rule are re-marked.
