VLAN used to transfer multicast traffic over the network avoiding duplication of multi-
cast streams for clients in different VLANs.

4.4.13.2 Group
Use the MVR Group Status page to view or configure MVR groups. MVR maintains
two types of group entries in its database, Static and Dynamic. Static entries are con-
figured by the administrator and Dynamic entries are learned by MVR on the source
ports.
Item Description
Admin Mode The administrative mode of MVR on the device.
MVR Mode The MVR learning mode, which can be one of the following:

Compatible: MVR does not learn source ports membership,
instead all source ports are members of all groups by default.
MVR does not forward IGMP Joins and Leaves from the hosts to
the router.

Dynamic: MVR learns source ports membership from IGMP que-
ries. MVR forwards the IGMP Joins and Leaves from the hosts to
the router.
The multicast traffic is forwarded only to the receiver ports that joined
the group, either by IGMP Joins or MVR static configuration.
Multicast VLAN A dedicated VLAN used to transfer multicast traffic over the network
avoiding duplication of multicast streams for clients in different VLANs.
Maximum Multicast
Groups The maximum number of membership groups that can be statically
configured in the MVR database.
Current Multicast
Groups The current number of membership groups that are statically config-
ured in the MVR database.
Query Response
Time (Tenths of Sec-
onds) The maximum time to wait for an IGMP membership report on a
receiver port before removing the port from the multicast group. The
query time is specified in tenths of a second.
