Configuration example
Ethernet 1/0/1 belongs to VLAN 2 and is connected to the 10.1.1.0/24 network segment.
Mark the DSCP precedence as 56 for the packets from the 10.1.1.0/24 network segment.
1) Method I: configure priority marking for port Ethernet 1/0/1
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule permit source 10.1.1.1 0.0.0.255
[Sysname-acl-basic-2000] quit
[Sysname] interface Ethernet1/0/1
[Sysname-Ethernet1/0/1] traffic-priority inbound ip-group 2000 dscp 56
2) Method II: configure priority marking for VLAN 2
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule permit source 10.1.1.1 0.0.0.255
[Sysname-acl-basic-2000] quit
[Sysname] traffic-priority vlan 2 inbound ip-group 2000 dscp 56
