Multicast VLAN Registration
– 511 –
■
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 “Adding Static
Members to VLANs” on page 140).
■
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 “Assigning Static MVR Multicast Groups to Interfaces” on page 512).
■
Non-MVR – An interface that does not participate in the MVR VLAN. (This is
the default type.)
◆ MVR Status – Shows the MVR status. MVR status for source ports is “Active” if
MVR is globally enabled on the switch. MVR status for receiver ports is “Active”
only if there are subscribers receiving multicast traffic from one of the MVR
groups, or a multicast group has been statically assigned to an interface.
◆ 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.
(This option only applies to an interface configured as an MVR receiver.)
Web Interface
To configure interface settings for MVR:
1. Click Multicast, MVR.
2. Select Configure Interface from the Step list.
3. Select Configure Port or Configure Trunk from the Action list.
4. Select an MVR domain.
5. Set each port that will participate in the MVR protocol as a source port or
receiver port, and optionally enable Immediate Leave on any receiver port to
which only one subscriber is attached.
6. Click Apply.
