show mld interface

Interface

Name of the interface.

Querier

Address of the router that has been elected to send membership queries.

State

State of the interface: Up or Down.

SSM Map Policy

Name of the source-specific multicast (SSM) map policy that has been applied to the interface.

SSM Map Policy

Name of the source-specific multicast (SSM) map policy at the MLD interface.

Timeout

How long until the MLD querier is declared to be unreachable, in seconds.

Version

MLD version being used on the interface: 1 or 2.

Groups

Number of groups on the interface.

Passive

State of the passive mode option:

• On—Indicates that the router can run IGMP or MLD on the interface but not send or receive control traffic such as IGMP or MLD reports, queries, and leaves.

• Off—Indicates that the router can run IGMP or MLD on the interface and send or receive control traffic such as IGMP or MLD reports, queries, and leaves.

The passive statement enables you to selectively activate up to two out of a possible three available query or control traffic options. When enabled, the following options appear after the on state declaration:

• send-general-query—The interface sends general queries.

• send-group-query—The interface sends group-specific and group-source-specific queries.

• allow-receive—The interface receives control traffic

OIF map

Name of the OIF map associated to the interface.

SSM map

Name of the source-specific multicast (SSM) map used on the interface, if configured.

Group limit

Maximum number of groups allowed on the interface. Any memberships requested after the limit is reached are rejected.

Group threshold

Configured threshold at which a warning message is generated.

This threshold is based on a percentage of groups received on the interface. If the number of groups received reaches the configured threshold, the device generates a warning message.

Group log-interval

Time (in seconds) between consecutive log messages.

Immediate Leave

State of the immediate leave option:

• On—Indicates that the router removes a host from the multicast group as soon as the router receives a multicast listener done message from a host associated with the interface.

• Off—Indicates that after receiving a multicast listener done message, instead of removing a host from the multicast group immediately, the router sends a group query to determine if another receiver responds.

Distributed

State of MLD, which, by default, takes place on the Routing Engine for MX Series routers but can be distributed to the Packet Forwarding Engine to provide faster processing of join and leave events.

• On—distributed MLD is enabled.

Configured Parameters

Information configured by the user.

• MLD Query Interval (.1 secs)—Interval at which this router sends membership queries when it is the querier.

• MLD Query Response Interval (.1 secs)—Time that the router waits for a report in response to a general query.

• MLD Last Member Query Interval (.1 secs)—Time that the router waits for a report in response to a group-specific query.

• MLD Robustness Count—Number of times the router retries a query.

Derived Parameters

Derived information.

• MLD Membership Timeout (.1 secs)—Timeout period for group membership. If no report is received for these groups before the timeout expires, the group membership will be removed.

• MLD Other Querier Present Timeout (.1 secs)—Time that the router waits for the IGMP querier to send a query.
