MLD interfaces field description

Use the data in the following table to use the Interfaces tab.

Field

Description

IfIndex

Specifies the internetwork layer interface value of the interface for which MLD is enabled.

QueryInterval

Specifies the frequency at which MLD host-query packets are transmitted on this interface. Values range from 1 to 65535.

Version

Indicates the MLD version.

Querier

Specifies the address of the MLD Querier on the IPv6 subnet to which this interface is attached.

QueryMaxResponseDelay

Specifies the maximum query response time advertised in MLD queries on this interface. Values range from 0 to 60.

Joins

Specifies the number of times a group membership has been added on this interface.

Groups

Specifies the current number of entries for this interface in the cache table.

Robustness

Specifies the robustness variable tuning for the expected packet loss on a subnet. If a subnet is expected to experience loss, the robustness variable can be increased. Values range from 2 to 255.

LastListenQueryIntvl

Specifies the maximum response delay inserted into the group-specific queries sent in response to the leave group messages. It also indicates the amount of time between group-specific query messages. Values range from 0 to 60.

This value can be tuned to modify the leave latency of the network. A reduced value results in reduced time to detect the loss of the last member of a group.

SnoopEnable

Indicates if snooping is enabled.

FlushAction

Specifies the MLD flush action as one of the following:
  • flushGrpMember

  • flushMrouter

  • flushSender

SsmEnable

Indicates if ssm is enabled.

NewQuerier

Specifies the IPv6 address of the new MLD querier.

DynamicDowngradeEnable

Enables dynamic downgrade of the MLD version when older version query message is received.

OperVersion

Specifies the operational version of the MLD running on this interface.

McastMode

Specifies the MLD interface mode as one of the following:
  • snoop

  • pim

  • snoopSpb

  • routerSpb

  • dvmrp

  • none
