Default MVR Configuration
Receiver ports cannot be trunk ports. Receiver ports on a switch can be in different VLANs, but
should not belong to the multicast VLAN.
The maximum number of multicast entries that can be configured on a switch (that is, the maximum
number of television channels that can be received) is 256.
Each channel is one multicast stream destined for a unique IP multicast address. These IP addresses
cannot alias between themselves or with the reserved IP multicast addresses (in the
range 224.0.0.xxx).
MVR does not support IGMPv3 messages.
Default Setting
