IGMP Snooping and VLANs
The Switch can perform IGMP snooping on up to 16 VLANs. You can configure the Switch to
automatically learn multicast group membership of any VLANs. The Switch then performs IGMP
snooping on the first 16 VLANs that send IGMP packets. This is referred to as auto
mode.
Alternatively, you can specify the VLANs that IGMP snooping should be performed on. This is
referred to as fixed
mode. In fixed mode the Switch does not learn multicast group membership of
any VLANs other than those explicitly added as an IGMP snooping VLAN.
