Mark a priority for the
incoming packets
matching the specific
ACL rules
traffic-priority inbound acl-rule { dscp
dscp-value | cos cos-value }
Required
User-defined traffic classification rules configured for priority marking in the global scope
or for a VLAN take precedence over the default rules used for processing protocol packets.
The device will execute priority marking preferentially, which may affect device
management implemented through Telnet and so on.
Configuration examples
# Mark the incoming packets from network segment 10.1.1.0/24 with DSCP value 56
(assuming that GigabitEthernet 1/0/1 carries VLAN 2 and is connected to network segment
10.1.1.0/24).
1) Method I: configure priority marking for port GigabitEthernet 1/0/1
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule permit source 10.1.1.0 0.0.0.255
[Sysname-acl-basic-2000] quit
[Sysname] interface GigabitEthernet1/0/1
[Sysname-GigabitEthernet1/0/1] 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 10.1.1.0 0.0.0.255
[Sysname-acl-basic-2000] quit
[Sysname] traffic-priority vlan 2 inbound ip-group 2000 dscp 56
