Enabling Ssm Mapping; Configuring Ssm Mappings - HP 4800G Series Configuration Manual

Configure basic functions of IGMP.

Enabling SSM Mapping

Follow these steps to enable the IGMP SSM mapping feature:
To do...
Enter system view
Enter interface view
Enable the IGMP SSM
mapping feature
To ensure SSM service for all hosts on a subnet, regardless of the IGMP version running on the hosts,
enable IGMPv3 on the interface that forwards multicast traffic onto the subnet.

Configuring SSM Mappings

By performing this configuration multiple times, you can map a multicast group to different multicast
sources.
Follow these steps to configure an IGMP SSM mapping:
To do...
Enter system view
Enter IGMP view
Configure an IGMP SSM
mapping
If IGMPv3 is enabled on a VLAN interface of a switch that supports both IGMP Snooping and IGMP,
and if a port in that VLAN is configured as a simulated host, the simulated host will send IGMPv3 reports
even if you did not specify a multicast source when configuring simulated joining with the
igmp-snooping host-join command. In this case, the corresponding multicast group will not be
created based on the configured IGMP SSM mappings. For details about the igmp-snooping
host-join command, refer to IGMP Snooping Commands in the IP Multicast Volume.
