c
Caution:
■
Before configuring a simulated host, enable IGMP Snooping in VLAN view first.
■
The port to be configured must belong to the specified VLAN; otherwise the
configuration does not take effect.
■
You can use the source-ip source-address command to specify a multicast
source address that the port will join as a simulated host. This configuration
takes effect when IGMPv3 Snooping is enabled in the VLAN.
Configuring a VLAN Tag
for Query Messages
By configuring the VLAN in which IGMP general and group-specific queries
forwarded and sent by IGMP Snooping switches are transmitted and by
configuring the VLAN mapping function, you can enable multicast packet
forwarding between different VLANs In a Layer-2 multicast network environment.
For description about VLAN mapping, see "VLAN-VPN"
n
It is not recommended to configure this function while the multicast VLAN
function is in effect.

After the configuration above, you can execute the following display commands in
any view to verify the configuration by checking the displayed information.
You can execute the reset command in user view to clear the statistics information
about IGMP Snooping.
