show ipv6 mld interface

Displays the IPv6 MLD interface information

Syntax

show ipv6 mld interface
show ipv6 mld interface gigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}
show ipv6 mld interface vlan <1-4059>

Command Parameters

gigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}: Displays the interface gigabitethernet MLD interface information. {slot/port[/sub-port][-slot/port[/sub-port]][,...]} identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If your platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
vlan <1-4059>: Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1.

Default

None

Command Output

The show ipv6 mld interface command displays the following information:


Output field	Description
IF	Specifies the internetwork layer interface value of the interface for which MLD is enabled.
STATUS	Indicates if MLD is activated on the interface.
VERSION	Indicates the version.
QUERIER	Indicates the address of the MLD Querier on the IPv6 subnet to which this interface attaches.
JOINS	Indicates the number of times a group membership has been added on this interface.
VLAN ID	Indicates the VLAN ID of the physical interface.
PORT NUM	Indicates the port number of the physical interface.
QUERY INTVL	Indicates the query interval, the frequency at which IPv6 MLD snooping host-query packets are transmitted on this interface.
QUERY MAX RESP	Indicates the maximum query response time advertised in IPv6 MLD snooping queries on this interface.
ROBUST	Indicates the robustness value.
LAST LIST QUERY	Indicates the last listener query interval. The last listener query interval is the maximum response delay inserted into group-specific queries sent in response to leave group messages, and it is also the amount of time between group-specific query messages.
SNOOP ENABLE	Indicates if snooping is enabled.
SSM SNOOP ENABLE	Indicates if ssm-snooping is enabled.
DYNAMIC DOWNGRADE ENABLE	Enables dynamic downgrade of the MLD version when older version query message is received.
