(Optional) Associating IGMP Proxy with NQA

(Optional) Associating IGMP Proxy with NQA

Context

Internet Group Management Protocol (IGMP) proxy lacks a fault detection mechanism to trigger link switchover quickly. Therefore, multicast services will be interrupted for a long time when a link failure occurs. You can solve this problem by associating IGMP proxy with a network quality analysis (NQA) test instance.

After IGMP proxy is associated with an NQA test instance, it can use the NQA test instance to monitor end-to-end link status. When the NQA test instance detects a link failure on the upstream interface, the switch with the IGMP proxy interface protection mode configured can trigger a switchover between the active/standby or active/active links quickly to minimize the communication interruption time.

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 icmp

    The test type is set to ICMP.

  4. Run:

    destination-address ipv4 ipv4-address

    The destination IP address for the ICMP test instance is configured.

  5. Run:

    quit

    Return to the system view.

  6. Run:

    interface interface-type interface-number

    The upstream interface view is displayed.

  7. (Optional) On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

  8. Run:

    igmp proxy track nqa admin-name test-name

    IGMP proxy is associated with the NQA test instance.

    By default, IGMP proxy on an interface is not associated with any NQA test instance.

    NOTE:
    The preceding procedure provides the basic configuration of an ICMP test instance. For details about NQA test instance configurations, see NQA Configuration in the S7700 and S9700 V200R010C00 Configuration Guide - Network Management.
