(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
- Run:
system-viewThe system view is displayed.
- Run:
nqa test-instance admin-name test-name
An NQA test instance is created and the test instance view is displayed.
- Run:
test-type icmp
The test type is set to ICMP.
- Run:
destination-address ipv4 ipv4-address
The destination IP address for the ICMP test instance is configured.
- Run:
quitReturn to the system view.
- Run:
interface interface-type interface-number
The upstream interface view is displayed.
- (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. - 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.
