Follow these steps to mark the priority for packets that are of a port group and match specific ACL rules: 

Enter system view 

system-view 

— 

Enter port group view 

port-group group-id 

— 

Mark the priorities for packets 
matching specific ACL rules 

traffic-priority inbound acl-rule { dscp 
dscp-value | cos cos-value }

Follow these steps to mark the priority for packets passing a port and matching specific ACL rules: 

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 acl-rule { dscp 
dscp-value | cos cos-value } 

Required 

 

As the priority of traffic classification rules is higher than that of the default rules used for processing 

protocol packets, marking priority for all the packets or packets of a VLAN may affect device 

management that is implemented through Telnet and so on. 

 

z 

GigabitEthernet 1/0/1 belongs to VLAN 2 and is connected to the 10.1.1.0/24 network segment. 

z 

Mark the DSCP precedence as 56 for the packets from the 10.1.1.0/24 network segment. 

1) Method 

I 

<device> system-view 

[device] acl number 2000 

[device-acl-basic-2000] rule permit source 10.1.1.1 0.0.0.255 

[device-acl-basic-2000] quit 

[device] interface GigabitEthernet1/0/1 

[device-GigabitEthernet1/0/1] traffic-priority inbound ip-group 2000 dscp 56 

2) Method 

II 

<device> system-view 

[device] acl number 2000 

[device-acl-basic-2000] rule permit source 10.1.1.1 0.0.0.255 

[device-acl-basic-2000] quit
