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).
Multicast routing and MVR cannot coexist on a switch. If you enable multicast routing and a
multicast routing protocol while MVR is enabled, MVR is disabled, and you receive a warning
message. If you try to enable MVR while multicast routing and a multicast routing protocol are
enabled, the operation to enable MVR is cancelled, and you receive an error message.
MVR does not support IGMPv3 messages.
