Multicast VLAN Registration 3

Configuring MVR Interface Status

Each interface that participates in the MVR VLAN must be configured as an MVR source port or receiver port. If only one subscriber attached to an interface is receiving multicast services, you can enable the immediate leave function.

Command Usage

•One or more interfaces may be configured as MVR source ports.

•MVR receiver ports cannot be members of a trunk. Receiver ports can belong to different VLANs, but should not be configured as a member of the MVR VLAN.

•IGMP snooping can be used to allow a source port or receiver port to dynamically join or leave multicast groups within the MVR VLAN using the standard rules for multicast filtering. Multicast groups can also be statically assigned to a source port or receiver port (see “Assigning Static Multicast Groups to Interfaces” on page 15-15).

•Immediate leave applies only to receiver ports. When enabled, the receiver port is immediately removed from the multicast group identified in the leave message. When immediate leave is disabled, the switch follows the standard rules by sending a group-specific query to the receiver port and waiting for a response to determine if there are any remaining subscribers for that multicast group before removing the port from the group list. Using immediate leave can speed up leave\ latency, but should only be enabled on a port attached to one multicast subscriber to avoid disrupting services to other group members attached to the same interface. Note that immediate leave does not apply to multicast groups which have been statically assigned to a port.

Command Attributes

•MVR Type – The following interface types are supported:

-Source – An uplink port that can send and receive multicast data for the groups assigned to the MVR VLAN.

-Receiver – A subscriber port that can receive multicast data sent through the

MVR VLAN.

-Non-MVR – An interface that does not participate in the MVR VLAN. (This is the default type.)

•Immediate Leave – Configures the switch to immediately remove an interface from a multicast stream as soon as it receives a leave message for that group.

•Trunk19 – Shows if port is a trunk member.
