Function

The display mld-snooping group-info command displays multicast group information dynamically learned on a specified interface.

Format

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

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

display mld-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-address	Displays dynamically learned information about a multicast group to which a specified multicast source sends data.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
group-address group-address	Displays dynamically learned information about a specified multicast group.	The value is a 32-digit hexadecimal number in X:X:X:X:X:X:X:X format. The value ranges from FF00:: to FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF.
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.
