Multicast VLAN Registration for IPv6
– 667 –
Receiver ports should not be statically configured as a member of the
MVR6 VLAN. If so configured, its MVR6 status will be inactive. Also,
note that VLAN membership for MVR6 receiver ports cannot be set to
access mode (see"Adding Static Members to VLANs" on page 198).
â—† One or more interfaces may be configured as MVR6 source ports. A
source port is able to both receive and send data for configured MVR6
groups or for groups which have been statically assigned (see
"Assigning Static MVR Multicast Groups to Interfaces" on page 652).
All source ports must belong to the MVR6 VLAN.
Subscribers should not be directly connected to source ports.
â—† 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.
â–
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.
â–
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:
â–
Non-MVR6 – An interface that does not participate in the MVR6
VLAN. (This is the default type.)
â–
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 198).
â–
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 198).
◆ Forwarding Status – Shows if multicast traffic is being forwarded or
blocked.
