If you want a report for a specific multicast group, enter that group’s address for
The vrf parameter specifies that you want to display IGMP group information for the VRF specified by the
Enter detail if you want to display the source list of the multicast group.

TABLE 21 Output of show ip igmp group
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. |
