display mld group static

Function

The display mld group static command displays information about static MLD multicast groups on interfaces.

Format

display mld group [ ipv6-group-address ] static [ up | down ] [ verbose ]

display mld group [ ipv6-group-address ] static interface-number

display mld group [ ipv6-group-address | interface interface-type interface-number ]^* static [ verbose ]

display mld group static interface interface-type interface-number entry-number

Parameters

Parameter	Description	Value
ipv6-group-address	Specifies an IPv6 multicast group address. If this parameter is not specified, the command displays information about all multicast groups with memberships.	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.
up \| down	Displays information about an Up or Down interface. If this parameter is not specified, the command displays information about all interfaces.	-
verbose	Displays detailed information about the interfaces that statically join MLD multicast groups or source-specific multicast groups. If this parameter is not specified, the command displays only the summary of the MLD group.	-
interface-number	Displays the number of the interfaces that statically join MLD multicast groups.	-
interface interface-type interface-number	Displays information about the MLD multicast groups that the specified interface statically joins.	-
entry-number	Displays the number of the MLD multicast groups that the interface statically joins.	-

Usage Guidelines

You can run the display mld group static command to view information about the multicast groups and the interfaces that statically join MLD multicast groups or source-specific multicast groups. To configure a static multicast group on an interface, run the mld static-group command.
