display igmp-snooping group-info listening interface

Function

The display igmp-snooping group-info listening interface command displays dynamically learned multicast group information on router QinQ sub-interfaces that are locally listened to.

Format

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

Parameters

Parameter	Description	Value
interface-type	Specifies the type of a QinQ sub-interface.	-
interface-number	Specifies the number of a QinQ sub-interface.	-
interface-name	Specifies the name of a QinQ sub-interface.	-
vsi vsi-name	Displays dynamically learned multicast group information in a specified VSI.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
user-mac mac-address	Displays dynamically learned multicast group information of a specified user MAC address.	The value is a unicast MAC address.
pe-vid vlan-id	Displays dynamically learned multicast group information with 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 with a specified inner VLAN ID.	The value is an integer ranging from 1 to 4094.
source-address ip-address	Displays dynamically learned multicast group information with a specified source address.	The value can be a Class A, B, or C address, in dotted decimal notation.
group-address group-address	Displays dynamically learned multicast group information with a specified group address.	The value is a Class D address, in dotted decimal notation.

Usage Guidelines

Usage Scenario

To dynamically learned multicast group information on QinQ sub-interfaces, run the display igmp-snooping group-info listening interface command.

Precautions

The command displays information only if multicast group information has been dynamically learned on QinQ sub-interfaces that are listened to.

Example

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