Multicast VLAN Registration for IPv6
– 609 –
membership for MVR6 receiver ports cannot be set to access mode (see“Adding
Static Members to VLANs” on page 169).
◆ 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 594).
All source ports must belong to the MVR6 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 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.
■
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 169).
■
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 169).
◆ 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
