23.2 Command Examples
This example enables IGMP snooping on the Switch, sets the
host-timeout
value to 30
seconds, and sets the Switch to drop packets from unknown multicast groups.
This example limits the number of multicast groups on port 1 to 5.
This example shows the current multicast groups on the Switch.
no igmp-immediate-leave
Disables the immediate leave function for IGMP snooping.

igmp-querier-mode
Specifies whether or not and under what conditions the
port(s) is (are) IGMP query port(s). The Switch forwards
IGMP join or leave packets to an IGMP query port, treating
the port as being connected to an IGMP multicast router (or
server). You must enable IGMP snooping as well.
fixed: The Switch always treats the port(s) as IGMP query
port(s). Select this when you connect an IGMP multicast
server to the port(s).
auto: The Switch uses the port as an IGMP query port if the
port receives IGMP query packets.
edge: The Switch does not use the port as an IGMP query
port. The Switch does 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.
