display igmp-snooping group-info

Function

The display igmp-snooping group-info command displays multicast group information of a local interface or a remote peer dynamically learned by the router.

Format

display igmp-snooping group-info interface { interface-type interface-number | interface-name } vlan vlan-id [ [ source-address source-ip-address ] group-address group-address ]

display igmp-snooping group-info interface { interface-type interface-number | interface-name } [ pe-vid vlan-id [ ce-vid vlan-id ] ] [ [ source-address source-ip-address ] group-address group-address ]

display igmp-snooping group-info interface { interface-type interface-number | interface-name } [ pe-vid vlan-id [ ce-vid vlan-id ] ] bridge-domain bd-id [ [ source-address source-ip-address ] group-address group-address ]

display igmp-snooping group-info

Parameters

Parameter	Description	Value
interface-name	Displays dynamically learned multicast group information of a specified interface.	-
vlan vlan-id	Displays dynamically learned multicast group information of a specified VLAN.	The value is an integer ranging from 1 to 4094.
source-address source-ip-address	Displays dynamically learned information about a multicast group to which a specified multicast source sends data.	The value can be a class A, B, or C address, in dotted decimal notation.
group-address group-address	Displays dynamically learned information about a specified multicast group.	The value is a class D address, in dotted decimal notation.
interface interface-type interface-number	Displays dynamically learned multicast group information of a specified interface.	-
pe-vid vlan-id	Displays dynamically learned multicast group information of a sub-interface that has a specified outer VLAN ID.	The value is an integer ranging from 1 to 4094.
ce-vid vlan-id	Displays dynamically learned multicast group information of a sub-interface that has a specified inner VLAN ID.	The value is an integer ranging from 1 to 4094.
bridge-domain bd-id	Displays dynamically learned multicast group information of a specified BD.	The value is an integer ranging from 1 to 16777215.

Usage Guidelines

Usage Scenario

To display multicast group information of a local interface or a remote peer dynamically learned by a device, run this command.

Precautions

This command has output only after the device has dynamically learned multicast group information of a local interface or a remote peer.

Example

The actual command output varies according to the device. The command output here is only an example.
