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 [vrf vrf-name] 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.
The vrf parameter specifies that you want to display IGMP group information for the VRF specified
by the vrf-name variable.
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.
This field
Displays
Group
The address of the multicast group
Port
The physical port on which the multicast group was received.
Intf
The virtual interface on which the multicast group was received.
Timer
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.
Mode
Indicates current mode of the interface: include or exclude. If the
interface is in Include mode, it admits traffic only from the source list. If
an interface is in exclude mode, it denies traffic from the source list and
accepts the rest.
Srcs
Identifies the source list that will be included or excluded on the
interface.
If IGMP V2 group is in exclude mode with a #_src of 0, the group
excludes traffic from 0 (zero) source list, which means that all traffic
sources are included.
