Statistics

The Multicast Forwarding Database Statistics page displays statistical information
about the multicast forwarding database (MFDB).

tics.

Figure 4.217 Switching > Multicast Forwarding Database > Statistics

The following table describes the items in the previous figure.

4.4.13

MVR

Multicast VLAN Registration (MVR) allows the switch to listen to the Internet Group
Management Protocol (IGMP) frames. Both protocols operate independently from
each other and can be enabled on the switch interfaces. In such case, MVR listens to
the Join and Report messages only for the statically configured groups. All other
groups are managed by IGMP snooping. MVR uses the multicast VLAN, a dedicated
VLAN used to transfer multicast traffic over the network avoiding duplication of multi-
cast streams for clients in different VLANs.

4.4.13.1

Global

Use the MVR Global Configuration page to view and configure the global settings for
MVR.
