Viewing IGMP Interface Information

Perform this procedure to view the IGMP interface table.

About this task

If an interface does not use an IP address, it does not appear in the IGMP table. One exception is an IGMP snooping interface, which does not require an interface IP address.

If an interface uses an IP address, but neither IGMP snoop or PIM is enabled, the interface appears as inactive in the Status field.

Procedure

Enter Privileged EXEC mode:

enable
View IGMP interfaces:

show ip igmp interface [gigabitethernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}|vlan <1-4059>] [vrf WORD<1–16>][vrfids WORD<0–512>]

Example

Variable Definitions

The following table defines parameters for the show ip igmp interface command.


Variable	Value
gigabitethernet `{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}`	Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port. If you do not specify a slot and port, the command output includes all IGMP interfaces.
vlan `<1-4059>`	Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. If you do not specify a VLAN ID, the command output includes all IGMP interfaces.
vrf `WORD <1–16>`	Optionally, identifies the VRF name. If you do not specify a VRF name, the results display information for the Global Router. If you specify a VRF name, the results display information only for the VRF you specify.
vrfids `WORD <0–512>`	Optionally, identifies the VRF ID. If you do not specify a range of VRF IDs, the results display information for the Global Router. If you specify a VRF ID or range of VRF IDs, the results display information only for the VRF you specify.
