Function

The display mld-snooping port-info command displays information about multicast interfaces, including static and dynamic member interfaces and router interfaces, on the Router.

Format

display mld-snooping port-info [ { vlan vlanid | vsi vsiName } [ group-address group-ipv6 ] ] [ verbose ]

display mld-snooping port-info [ vsi vsiName [ vlan vlanid ] ] [ group-address group-ipv6 ] [ verbose ]

Parameters

Parameter	Description	Value
vlan vlanid	Displays information about multicast interfaces in a specified VLAN.	The value is an integer ranging from 1 to 4094.
vsi vsiName	Displays information about multicast interfaces 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.
group-address group-ipv6	Displays information about multicast interfaces of specified multicast group in a specified VLAN/VSI.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X. The value ranges from FF00::0 to FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF.

Usage Guidelines

Usage Scenario

The command displays information only after MLD snooping is enabled globally and in a specified VLAN/VSI view.

When using the command to view information about multicast interfaces in a VSI, you can view only the PW interfaces and sub-interfaces of multicast groups. If a VLANIF interface is bound to a VSI, information about this VLANIF interface cannot be displayed. If you need to view the information, view the multicast interface information in the VLAN.

Information about multicast member interfaces is displayed only when these member interfaces are in the Up state. When using the command, note the following points:

The display mld-snooping port info command displays information about all multicast interfaces.
The display mld-snooping port info vlan command displays information about all multicast interfaces in a specified VLAN.
The display mld-snooping port info vsi command displays information about all multicast interfaces in a specified VSI.
The display mld-snooping port info vlan group-address command displays information about interfaces of a specified multicast group in a specified VLAN.
The display mld-snooping port info vsi group-address command displays information about interfaces of a specified multicast group in a specified VSI.

Example

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