Chapter 14 | Multicast Filtering
Multicast VLAN Registration for IPv6
– 628 –
■
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:
◆ Domain ID – An independent multicast domain. (Range: 1-5)
◆ Port/Trunk – Interface identifier.
◆ Type – The following interface types are supported:
■
Non-MVR6 – An interface that does not participate in the MVR6 VLAN.
(This is the default type.)
■
Source – An uplink port that can send and receive multicast data for the
groups assigned to the MVR6 VLAN. Note that the source port must be
manually configured as a member of the MVR6 VLAN (see “Adding Static
Members to VLANs” on page 171).
■
Receiver – A subscriber port that can receive multicast data sent through
the MVR6 VLAN. Also, note that VLAN membership for MVR receiver ports
cannot be set to access mode (see “Adding Static Members to VLANs” on
page 171).
◆ Forwarding Status – Shows if multicast traffic is being forwarded or blocked.
◆ MVR6 Status – Shows the MVR6 status. MVR6 status for source ports is “Active”
if MVR6 is globally enabled on the switch. MVR6 status for receiver ports is
“Active” only if there are subscribers receiving multicast traffic from one of the
MVR6 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 MVR6 receiver.)
(Default: Disabled)
■
By Group – The receiver port is immediately removed from the multicast
group identified in the MLD snooping leave message.
■
By Host IP – The router/querier will not send out a group-specific query
when an MLD snooping 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.
