Quidway S7700 Smart Routing Switch
Configuration Guide - QoS

1.3.6 Checking the Configuration

After priority mapping based on simple traffic classification is configured, you can view the
mapping between packet priorities and PHBs and the mapping between local precedences and
queues.
Prerequisite
The configurations of priority mapping based on simple traffic classification are complete.

1.4 Creating a Traffic Policy Based on Complex Traffic
Classification
After the traffic policy based on complex traffic classification is configured, the S7700 classifies
packets according to the priority of packets and quintuple information. Then the S7700 takes
different traffic actions for packets matching classification conditions, such as permit/deny, re-
marking, and redirection.

1.4.1 Establishing the Configuration Task

Before configuring the traffic policy based on complex traffic classification, familiarize yourself
with the applicable environment, complete the pre-configuration tasks, and obtain the required
data. This helps you complete the configuration task quickly and accurately.
Applicable Environment
At the ingress of a network, the S7700 functions as a border node. To limit the incoming traffic
on a network, the S7700 can provide differentiated services for various services according to
the DSCP field, protocol type, IP address, port number, fragmentation type, and time range of
packets. In this case, you need to create a traffic policy based on complex traffic classification.
Generally, complex traffic classification is configured on a border node, and simple traffic
classification is configured on a core node.
Pre-configuration Tasks
Before creating a traffic policy based on complex traffic classification, complete the following
tasks:
