Chapter 14 | Multicast Filtering
Multicast VLAN Registration for IPv4
– 612 –
◆ 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 “Adding Static
Members to VLANs” on page 171).
■
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 613).
■
Non-MVR – An interface that does not participate in the MVR VLAN. (This is
the default type.)
◆ Forwarding Status – Shows if MVR traffic is being forwarded or discarded.
◆ 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.
(Default: Disabled)
■
By Group – The receiver port is immediately removed from the multicast
group identified in the leave message.
■
By Host IP – The router/querier will not send out a group-specific query
when an IGMPv2/v3 leave message is received (the same as it would
without this option having been used). Instead of immediately deleting
that group, it will look up the record, and only delete the group if there are
no other subscribers for it on the member port. Only when all hosts on that
port leave the group will the member port be deleted.
