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

Defaults
MVR is disabled by default.
The default MVR mode is compatible mode.
Cisco ME 3400 Ethernet Access Switch Command Reference
2-290
mvr [group ip-address [count] | mode [compatible | dynamic] | querytime value | ringmode flood
| vlan vlan-id]
no mvr [group ip-address | mode [compatible | dynamic] | querytime | ringmode flood | vlan
vlan-id]
Statically configure an MVR group IP multicast address on the switch.
Use the no form of this command 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) Configure multiple contiguous MVR group addresses. The range
is 1 to 2000. However, if the mode is compatible, the switch allows only 512
groups, even if you enter a value greater than 512. Dynamic mode supports
2000 groups. The default is 1.
(Optional) Specify the MVR mode of operation.
The default is compatible mode.
Set MVR mode to provide compatibility with Catalyst 2900 XL and
Catalyst 3500 XL switches. This mode does not allow dynamic membership
joins on source ports.
Set MVR mode to allow dynamic MVR membership on source ports.
(Optional) Set 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) Enable MVR ring mode flooding for access rings. Entering this
command controls traffic flow in egress ports in a ring environment to
prevent the dropping of unicast traffic.
(Optional) Specify 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.
