IGMP v3

To display the status of one IGMP multicast group, enter a command such as the following.
If the tracking and fast leave feature is enabled, you can display the list of clients that belong to a
particular group by entering commands such as the following.
Syntax: show ip igmp group [ <group-address> [detail] [tracking]]
If you want a report for a specific multicast group, enter that group’s address for <group-address> .
Omit the <group-address> if you want a report for all multicast groups.
Enter detail if you want to display the source list of the multicast group.
Enter tracking if you want information on interfaces that have tracking enabled.
IGMP V2 and V3 statistics displayed on the report for each interface.
Table 0.1:
This field Displays
Group The address of the multicast group
Phy-port The physical port on which the multicast group was received.
Static A “yes” entry in this column indicates that the multicast group was configured
as a static group; “No” means it was not. Static multicast groups can be
configured in IGMP V2 using the ip igmp static command. In IGMP V3, static
sources cannot be configured in static groups.
Querier “Yes” means that the port is a querier port; “No” means it is not. A port
becomes a non-querier port when it receives a query from a source with a
lower source IP address than the port.
Life Shows the number of seconds the interface can remain in exclude mode. An
exclude mode changes to include mode if it does not receive an "IS_EX" or
"TO_EX" message during a certain period of time. The default is 140 seconds.
There is no “life” displayed in include mode.
