Displays information about a statically configured or dynamically learned IGMP group. If you do not specify a VRF name or range of VRF IDs, the results show information for the Global Router. If you do specify a VRF name or range of VRF IDs, the results show information only for the VRFs you specify.

The CLI command show ip igmp group displays both static and dynamically learned IGMP groups, and the CLI command show ip igmp static command displays only the statically configured IGMP groups. In contrast, the EDM display command under IP > IGMP > Groups displays the dynamically learned groups, and the EDM command under IP > IGMP > Static displays the statically configured IGMP groups.
The show ip igmp group command displays the following information:

Output field |
Description |
|---|---|
|
GRPADDR |
Indicates the multicast group address (Class D) that others want to join. Many incoming ports can use the same group address. |
|
INPORT |
Indicates the physical interface or a logical interface (VLAN), which received group reports from various sources. |
|
MEMBER |
Indicates the IP address of a source that sent a group report to join this group. |
|
EXPIRATION |
Indicates the time left before the group report expires on this port. The port updates this variable after it receives a group report. |
|
TYPE |
Indicates whether the entry is learned dynamically or is added statically. |
|
L2ISID |
Indicates the I-SID associated with the Layer 2 interface. |
