Huawei quidway s7700 - Creating a Diffserv Domain and Configuring Priority Mapping

The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
Step 3 Run:
port priority priority-value
The default 802.1p priority of the interface is set.
By default, the 802.1p priority of an interface is 0.
NOTE
The default 802.1p priority of an interface cannot be set on X40SFC boards.

1.3.4 Creating a DiffServ Domain and Configuring Priority
Mapping
When the S7700 functions as a border node between a DiffServ domain and other networks, you
need to configure mappings between internal priorities (PHBs and colors) and external priorities
(such as 802.1p priorities, DSCP priorities, and EXP priorities).
Context
A DiffServ domain is composed of a group of interconnected DiffServ nodes that use the same
service policy and PHBs.
In the DiffServ domain, the S7700 maps priorities of incoming packets to PHBs and colors. On
the S7700, congestion management is performed for packets based on PHBs of packets and
congestion avoidance is performed for packets based on colors of packets. If packets are sent to
a downstream device, the S7700 binds a DiffServ domain to the outbound interface. In the
DiffServ domain, the S7700 maps PHBs and colors of packets to priorities so that the
downstream device provides QoS services based on priorities of packets.
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.
In the default DiffServ domain, mappings from priorities of packets to PHBs and colors are
defined. You can change the mappings defined in the default DiffServ domain, but cannot delete
the default DiffServ domain.
In addition to the default DiffServ domain, a maximum of seven domains can be created on the
S7700.
