Configuration Guide - QoS
rate of packets exceeds the CIR, certain devices set the DEI field of the packets to 1. That is,
these packets have a high drop priority. If congestion occurs, subsequent devices first discard
packets with the DEI field as 1.
Do as follows on the S9300 where the CFI as the internal drop priority needs to be configured.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:

The interface view is displayed.
Step 3 Run:

The CFI field is configured as the internal drop priority.
By default, the CFI field is not configured as the internal drop priority.

1.3.6 Applying a DiffServ Domain

Context
To map priorities of packets coming from an upstream device to PHBs and colors according to
the mapping defined in a DiffServ domain, you can bind the DiffServ domain to the incoming
interface. The system then maps priorities of packets to PHBs and colors according to the
mapping defined in the DiffServ domain.
To map PHBs to priorities of packets sent to a downstream device according to the mapping
defined in a DiffServ domain, you can bind the DiffServ domain to the outgoing interface. The
system then maps PHBs and colors to priorities of packets according to the mapping defined in
the DiffServ domain.
Do as follows on the S9300 that a DiffServ domain needs to be applied to.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
