H3C S3100-52P Ethernet Switch

through all the router ports in the VLAN and all member ports of that multicast group,

and performs the following to the receiving port:

If any IGMP report in response to the group-specific query arrives to the member

port before its aging timer expires, this means that some other members of that

multicast group still exist under that port: the switch resets the aging timer of the

member port.

If no IGMP report in response to the group-specific query arrives to the member

port before its aging timer expires as a response to the IGMP group-specific query,

this means that no members of that multicast group still exist under the port: the

switch deletes the forwarding entry corresponding to the port from the forwarding

table when the aging timer expires.

After an Ethernet switch enables IGMP Snooping, when it receives the IGMP leave

message sent by a host in a multicast group, it judges whether the multicast group

exists automatically. If the multicast group does not exist, the switch drops this IGMP

leave message.
