Operation Manual – Multicast
H3C S5600 Series Ethernet Switches
When receiving an IGMP general query, the simulated host responds with an
IGMP report. Meanwhile, the simulated host sends the same IGMP report to itself
to ensure that the IGMP entry does not age out.
When the simulated joining function is disabled on an Ethernet port, the simulated
host sends an IGMP leave message.
Therefore, to ensure that IGMP entries will not age out, the port must receive IGMP
general queries periodically.
I. Configuring simulated joining in interface view
Follow these steps to configure simulated joining in interface view:
Enter system view
Enter interface view
Configure one or more
ports in the VLAN as
simulated member host(s)
of the specified multicast
group
II. Configuring simulated joining in Ethernet port view
Follow these steps to configure simulated joining in Ethernet port view:
Enter system view
Enter Ethernet port view
Configure the port in the specified
VLAN as a simulated member
host of the specified multicast
group
Caution:
Before configuring simulated joining, you must enable IGMP in interface view first.
If you configure simulated joining in Ethernet port view, the Ethernet port must
belong to the specified VLAN; otherwise the configuration does not take effect.
