80.30 IGMP Snooping VLAN
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.
Click SWITCHING > Multicast > IGMP Snooping VLAN to display the screen as shown.
Note: You can perform IGMP snooping on up to 16 VLANs.

IGMP Querier
Mode
The Switch treats an IGMP query port as being connected to an IGMP multicast router (or
server). The Switch forwards IGMP join or leave packets to an IGMP query port.
Select Auto to have the Switch use the port as an IGMP query port if the port receives IGMP
query packets.
Select Fixed to have the Switch always use the port as an IGMP query port. Select this when
you connect an IGMP multicast server to the port.
Select Edge to stop the Switch from using the port as an IGMP query port. The Switch will not
keep any record of an IGMP router being connected to this port. The Switch does not forward
IGMP join or leave packets to this port.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
