Creating An Nqa Mtrace Test - Huawei S9300 Configuration Manual

S9300&S9300E Terabit Routing Switch
Configuration Guide - Network Management
Applicable Environment
To check the Reverse Path Forwarding (RPF) path from the multicast source to the querier, you
can perform the NQA MTrace test.
By performing the MTrace test, you can obtain the possible transmission path of multicast
packets. During the test, actual multicast data flows are not required.
The MTrace test can be used in multicast troubleshooting and routine maintenance to locate the
faulty nodes and reduce configuration errors.
Pre-configuration Tasks
Before configuring the MTrace test, you must enable the multicast function in the network.
Data Preparation
To configure the MTrace test, you need the following data.

6.20.2 Creating an NQA MTrace Test

This part describes how to configure an MTrace instance before performing the MTrace test for
the RPF path from the multicast source to the querier.
Context
Do as follows on the switch that functions as the NQA client:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
nqa test-instance admin-name test-name
