C HAPTER 4 | Configuring the Switch
Multicast VLAN Registration
– 141 –
2. Set the interfaces that will join the MVR as source ports or receiver
ports.
3. If you are sure that only one subscriber attached to an interface is
receiving multicast services, you can enable the immediate leave
function.
◆ Although MVR operates on the underlying mechanism of IGMP
snooping, the two features operate independently of each other. One
can be enabled or disabled without affecting the behavior of the other.
However, if IGMP snooping and MVR are both enabled, MVR reacts only
to join and leave messages from multicast groups configured under
MVR. Join and leave messages from all other multicast groups are
managed by IGMP snooping. Also, note that only IGMP version 2 or 3
hosts can issue multicast leave messages. Immediate leave therefore
cannot be used for IGMP version 1 clients.
PARAMETERS
These parameters are displayed:
MVR Configuration
◆ MVR Mode – When MVR is enabled on the switch, any multicast data
associated with an MVR group is sent from all designated source ports,
to all receiver ports that have registered to receive data from that
multicast group. (Default: Disabled)
VLAN Interface Settings
◆ MVR VID – Identifier of the VLAN that serves as the channel for
streaming multicast services using MVR. MVR source ports should be
configured as members of the MVR VLAN, but MVR receiver ports
should not be manually configured as members of this VLAN.
(Default: 100)
◆ MVR Name – An optional attribute used to indicate the name of a
specific MVR VLAN. (Range: 1-32 alphanumeric characters, containing
at least one alphabetic character)
◆ Mode – Specify the MVR mode of operation:
■
Dynamic – MVR allows dynamic MVR membership reports on
source ports. (This is the default.)
■
Compatible – MVR membership reports are forbidden on source
ports.
◆ Tagging – Specifies whether the traversed IGMP/MLD control frames
will be sent untagged or tagged with the MVR VID. (Default: Tagged)
◆ Priority – Specifies the priority for transmitting traversed IGMP/MLD
control frames. (Default: 0)
◆ LLQI – Last Listener Query Interval is the maximum time to wait for
IGMP/MLD report memberships on a receiver port before removing the
