You can use the traffic priority command to mark the IP precedence, 802.1p priority, DSCP
precedence, and local precedence of the packets.
Configuration prerequisites
The following items are defined or determined before the configuration:
z The ACL rules used for traffic classification have been specified. Refer to the ACL module of this
manual for related information.
z The type and value of the precedence to be marked for the packets matching the ACL rules have
been determined.
z The port or VLAN on which the configuration is to be performed has been determined.
Configuration procedure
Follow these steps to configure priority marking on a port:
To do… Use the command… Remarks
Enter system view system-view —
Enter Ethernet port view
interface interface-type
interface-number
—
Mark the priorities for packets
matching specific ACL rules
traffic-priority { inbound | outbound }
acl-rule { { dscp dscp-value |
ip-precedence { pre-value | from-cos } }
| cos { pre-value | from-ipprec } |
local-precedence pre-value }* Required
Refer to the command
manual for information
about the acl-rule
argument.
Follow these steps to configure priority marking on a VLAN:
To do… Use the command… Remarks
Enter system view system-view —
Mark the priorities for the
packets belonging to a VLAN
and matching specific ACL
rules
traffic-priority vlan vlan-id { inbound
| outbound } acl-rule { { dscp
dscp-value | ip-precedence
{ pre-value | from-cos } } | cos
{ pre-value | from-ipprec } |
local-precedence pre-value }*
Required
Refer to the command
manual for information
about the acl-rule
argument.
Configuration example
z Ethernet 1/0/1 belongs to VLAN 2 and is connected to the 10.1.1.1/24 network segment.
z Mark the DSCP precedence as 56 for the packets from the 10.1.1.1/24 network segment.
