[ remark-8021p 8021p-value | remark-dscp dscp-value ] } ] [ yellow { drop
| pass [ remark-8021p 8021p-value | remark-dscp dscp-value ] } ] [ red

Traffic policing is configured for the incoming packets matching an ACL rule on an
interface.
Or, run:
traffic-limit outbound { acl { [ ipv6 ] { bas-acl | adv-acl | name acl-
name } | l2-acl } } [ rule rule-id ] cir cir-value [ pir pir-value ]
[ cbs cbs-value pbs pbs-value ] [ [ green { drop | pass [ remark-8021p
8021p-value | remark-dscp dscp-value ] } ] [ yellow { drop | pass
[ remark-8021p 8021p-value | remark-dscp dscp-value ] } ] [ red { drop |
pass [ remark-8021p 8021p-value | remark-dscp dscp-value ] } ] ]
Traffic policing is configured for the outgoing packets matching an ACL rule on an
interface.
NOTE
The colors of packets can be defined in traffic policing:
l When the size of a packet is less than the value of cbs-value, the packet is colored green.
l When the size of a packet is greater than or equal to the value of cbs-value but less than
the value of pbs-value, the packet is colored yellow.
l When the size of a burst packet is greater than or equal to the value of pbs-value, the packet
is colored red.
By default, green packets and yellow packets are allowed to pass through, and red packets are
discarded.
When the traffic-limit 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-limit command does not take
effect.
l If the permit action is configured in the ACL rule, the traffic-limit command takes effect.
A Layer 2 ACL and a Layer 3 ACL can be set in the traffic-limit 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-limit inbound acl { l2-acl | name acl-name } [ rule rule-id ] acl { bas-acl | adv-acl |
name acl-name } [ rule rule-id ] cir cir-value [ pir pir-value ] [ cbs cbs-value pbs pbs-
value ] [ [ green { drop | pass [ remark-8021p 8021p-value | remark-dscp dscp-value ] } ]
[ yellow { drop | pass [ remark-8021p 8021p-value | remark-dscp dscp-value ] } ] [ red
{ drop | pass [ remark-8021p 8021p-value | remark-dscp dscp-value ] } ] ]
To configure both Layer 2 ACLs and Layer 3 ACLs on an outbound interface of a switch, use
the following command:
traffic-limit outbound acl { l2-acl | name acl-name } [ rule rule-id ] acl { bas-acl | adv-acl
| name acl-name } [ rule rule-id ] cir cir-value [ pir pir-value ] [ cbs cbs-value pbs pbs-
value ] [ [ green { drop | pass [ remark-8021p 8021p-value | remark-dscp dscp-value ] } ]
[ yellow { drop | pass [ remark-8021p 8021p-value | remark-dscp dscp-value ] } ] [ red
{ drop | pass [ remark-8021p 8021p-value | remark-dscp dscp-value ] } ] ]
