mvr (global configuration)
To enable the multicast VLAN registration (MVR) feature on the switch, use the mvr global
configuration command without keywords. Use the command with keywords to set the MVR mode for
a switch, to configure the MVR IP multicast address, to specify the MVR multicast VLAN, and to set
the maximum wait time for a query reply before removing a port from group membership. Use the no
form of this command to return to the default settings.

Statically configures an MVR group IP multicast address on the switch.
Use the no form of this command either to remove a statically configured IP
multicast address or contiguous addresses, or when no IP address is entered,
to remove all statically configured MVR IP multicast addresses.
(Optional) Configures multiple contiguous MVR group addresses. The range
is 1 to 1500.
(Optional) Specifies the MVR mode of operation.
The default is compatible mode.
Sets MVR mode to disallow dynamic membership joins on source ports.
Sets MVR mode to allow dynamic MVR membership on source ports.
(Optional) Sets the maximum time to wait for IGMP report memberships on
a receiver port. This time applies only to receiver-port leave processing.
When an IGMP query is sent from a receiver port, the switch waits for the
default or configured MVR querytime for an IGMP group membership
report before removing the port from multicast group membership.
The value is the response time in units of tenths of a second. The range is 1
to 100; the default is 5 tenths (one-half second).
Use the no form of the command to return to the default setting.
(Optional) Specifies the VLAN on which MVR multicast data is to be
received. This is also the VLAN to which all the source ports belong. The
range is 1 to 4094. The default is VLAN 1.
