(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-view
The 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 quit
Return 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.
Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
- 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.
The preceding procedure provides the basic configuration of an ICMP test instance. For details about NQA test instance configurations, see NQA Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - Network Management.
