Configuring The Diffserv Domain; Setting The Mapping Of The Precedence In The Mpls Tunnel Label - Huawei Quidway S9300 series Configuration Manual

Quidway S9300 Terabit Routing Switch
Configuration Guide - MPLS
Applicable Environment
To implement certain QoS functions on an MPLS network, the S9300 needs to determine the
packet precedence according to the tunnel label of the MPLS public network. Therefore, you
need to map the tunnel label to the EXP field.
Pre-configuration Tasks
Before setting the mapping of the precedence in the tunnel label, complete the following task:
l
Data Preparation
None.

2.13.2 Configuring the DiffServ Domain

Context
A DiffServ domain comprises the connected DiffServ nodes, which use the same service policy
and implement the same PHBs.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
diffserv domain { default | ds-domain-name }
A DiffServ domain is created and the DiffServ domain view is displayed.
The default domain defines the default mappings from packet priorities to PHBs and colors.
You can modify the mappings defined in the default domain but cannot delete the default
domain.
