Receiver ports should not be configured as a member of the MVR VLAN. Also, note
that VLAN membership for MVR receiver ports cannot be set to access mode (see
"Adding Static Members to VLANs" on page
•
One or more interfaces may be configured as MVR source ports. A source port is
able to both receive and send data for configured MVR groups or for groups which
have been statically assigned (see
on page
18-28).
All source ports must belong to the MVR VLAN.
Subscribers should not be directly connected to source ports.
•
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 query message 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.
•
Immediate leave does not apply to multicast groups which have been statically
assigned to a port.
Parameters
These parameters are displayed in the web interface:
•
Port – Port identifier.
•
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. Note that the source port must be manually
configured as a member of the MVR VLAN (see
VLANs" on page
•
Receiver – A subscriber port that can receive multicast data sent through the
MVR VLAN. Any port configured as a receiver port will be dynamically added to
the MVR VLAN when it forwards an IGMP report or join message from an
attached host requesting any of the designated multicast services supported by
the MVR VLAN. Just remember that only IGMP version 2 or 3 hosts can issue
multicast join or leave messages. If MVR must be configured for an IGMP
version 1 host, the multicast groups must be statically assigned (see
Static Multicast Groups to Interfaces" on page
•
Non-MVR – An interface that does not participate in the MVR VLAN. (This is the
default type.)
•
Oper. Status – Shows the link status.
