Enabling The Function Of Simulating Member Hosts - H3C S5500-SI Series Manual

Operation Manual – Multicast Protocol
H3C S5500-SI Series Ethernet Switches
Note:
The function of static joining to a multicast source/group is available only if a valid
multicast source address is specified and IGMP Snooping version 3 is currently
running.
When you configure or remove a port as a static member port of a multicast group or
multicast source/group, the port will not initiate an IGMP report or an IGMP leave
message.
Static member ports and static router ports never age out. To delete such a port, you
need to use the corresponding command.

1.4.3 Enabling the Function of Simulating Member Hosts

Generally, a host running IGMP responds to IGMP queries from a multicast router. If a
host fails to respond due to some reasons, the multicast router will deem that no
member of this multicast group exists on the network segment, and therefore will
remove the corresponding forwarding path.
To avoid this situation from happening, you can configure a port of the switch as a
member of the multicast group(namely, enable the function of simulating member hosts
on the port). When an IGMP query arrives, that member port will give a response. As a
result, the switch can continue receive multicast data.
Through this configuration, the following functions can be implemented:
When the function of simulating member hosts is enabled on an Ethernet port, the
simulated host sends an IGMP report.
When receiving an IGMP general query, the simulated host responds with an
IGMP report just like a real host.
When the function of simulating member hosts is disabled on an Ether port, the
simulated host sends an IGMP leave message.
Follow these steps to enable the function of simulating member hosts:
