Table 49. MLD Snooping Querier VLAN Configuration information
Field Description
Operational State The operational state of the MLD snooping querier on a VLAN. It can be in any of the
following states:
Operational Version The operational MLD protocol version of the querier.
Last Querier Address The IP address of the last querier from which a query was snooped on the VLAN.
Last Querier Version The MLD protocol version of the last querier from which a query was snooped on the
VLAN.
Operational Max
Response T
ime
The maximum response time to be used in the queries that are sent by the snooping
querier.
Configure multicast VLAN registration
IGMP snooping helps limit multicast traffic when member ports are in the same VLAN.
However, when ports belong to different VLANs, a copy of the multicast stream is sent to
each VLAN with member ports in the multicast group. Multicast VLAN registration (MVR)
eliminates the need to duplicate the multicast traffic when multicast group member ports
belong to different VLANs.
MVR uses a dedicated multicast VLAN to forward multicast traffic over the L2 network. Only
one multicast source VLAN (MVLAN can be configured per switch, and it is used only for
certain multicast traf
fic, such as traf
fic from an IPTV application, to avoid duplication of
multicast streams for clients in different VLANs. Clients can dynamically join or leave the
multicast VLAN without interfering with their membership in other VLANs.
MVR, like IGMP snooping, allows a Layer 2 switch to listen to IGMP messages to learn about
multicast group membership.
You can configure basic, advanced, group, interface, or group membership settings.
• Querier. Snooping switch is the querier in the VLAN. The snooping switch sends
out periodic queries with a time interval equal to the configured querier query
interval. If the snooping switch sees a better querier in the VLAN, it moves to
non-querier mode.
• Non-Querier. Snooping switch is in non-querier mode in the VLAN. If the querier
expiry interval timer is expired, the snooping switch moves into querier mode.
• Disabled. Snooping querier is not operational on the VLAN. The snooping querier
moves to disabled mode when MLD snooping is not operational on the VLAN or
when the querier address is not configured or the network management address is
also not configured.
