Enabling Igmp Nsr; Displaying And Maintaining Igmp - HP FlexFabric 5950 series Configuration Manual

3. Enable multicast load
splitting.

Enabling IGMP NSR

This feature backs up information about IGMP interfaces and IGMP multicast groups to the standby
process. The device recovers the information without cooperation of other devices when an
active/standby switchover occurs. Use this feature to prevent an active/standby switchover from
affecting the multicast service.
To enable IGMP NSR:
Step
1. Enter system view.
2. Enable IGMP NSR.

Displaying and maintaining IGMP

CAUTION:
The reset igmp group command might cause multicast data transmission failures.
Execute display commands in any view and reset commands in user view.
Task
Display information about IGMP multicast
groups.
Display IGMP information for interfaces.
Display multicast group membership
information maintained by the IGMP proxy.
Display multicast routing entries maintained
by the IGMP proxy.
Display IGMP SSM mappings.

entries.
