Multicast Filtering

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
3-180).
• 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.
•
Trunk
13
– Shows if port is a trunk member.
