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.
Configuration example
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
[device] traffic-priority vlan 2 inbound ip-group 2000 dscp 56
