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.
