Configuring the NQA MTrace Test to Check the Multicast Path from the Multicast Source to the Querier

Configuring the NQA MTrace Test to Check the Multicast Path from the Multicast Source to the Querier

Context

To check the multicast path from the multicast source to the querier, you can perform the NQA MTrace test.

During this test, actual multicast data flows are required in the network and the querier must reside on the multicast distribution tree. This test can be used to trace the actual forwarding path of packets.

This test provides the following functions:

  • It can be used in multicast troubleshooting and routine maintenance to locate the faulty nodes and reduce configuration errors.

  • It collects traffic through cyclic path tracing and calculates the multicast traffic rate.

  • It outputs the test result containing the information about the faulty nodes, based on which the NM Station can analyze the fault and generate alarms.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run nqa test-instance admin-name test-name

    An NQA test instance is created and the test instance view is displayed.

  3. Run test-type mtrace

    The test type is set to MTrace.

  4. Run mtrace-source-address ipv4 ip-address

    The address of the multicast source is specified.

  5. Run mtrace-group-address ipv4 ip-address

    The multicast group address is configured. The address must be a common group address.

  6. (Optional) Run vpn-instance vpn-instance-name

    The VPN instance name is configured.

  7. (Optional) Adjust the performance of the NQA MTrace test instance.

    • Run ttl number

      The TTL value, that is, the maximum hops traced in max-hop mode is set for the IGMP-Tracert-Request packet.

    • Run tracert-livetime first-ttl first-ttl max-ttl max-ttl

      The maximum hops traced in hop-by-hop mode is set. first-ttl must be set to 1.

    • Run mtrace-response-address ipv4 ip-address [ ttl value ]

      The destination IP address and TTL of the IGMP-Tracert-Response packet are set.

    • Run description string

      A description is configured for the test instance.

    • Run frequency interval

      The test period is set for the NQA test instance.

    • Run timeout time

      The timeout period of a probe is set for the NQA test instance.

    • Run probe-count number

      The number of probes in each test is set.

    • Run records result number

      The maximum number of result records is set for the NQA test instance.

    • Run agetime hh:mm:ss

      The aging time is set for the NQA test instance.
