mvr group
The
mvr group
command, in Global Configuration mode, statically configures an MVR
group IP multicast address on the switch.
The
no
form of this command, with an IP address specified, removes the specified statically
configured IP multicast. If no IP address is specified, the
no
form of this command removes
all statically configured MVR IP multicast addresses.
By default, no IP multicast addresses are configured on the switch. The default group IP
address count is 1.
Use the
mvr group
command to statically set up all the IP multicast addresses that will take
part in MVR.
Command Syntax
device-name(config)#
mvr
group
A.B.C.D
[<
count>
]
device-name(config)#
no mvr
group
[
A.B.C.D
]
Argument Description
A.B.C.D
The IP multicast address of the MVR group.
count
(Optional) Configure multiple contiguous MVR group addresses. The default is 1. The
allowed range is 1-256.
Example
See the examples below.
mvr querytime
The optional
mvr querytime
command, in Global Configuration mode, sets the maximum
time to wait for IGMP report memberships on a receiver port. This time applies only to
receiver-ports and affects leave processing. When an IGMP query is sent to a receiver port,
the switch waits for the default or configured MVR query-time for an IGMP group
membership report before removing the port from multicast group membership.
This command overrides the query response time indicated in the IGMP query packets
received from the query router.
The
no
form of this command restores the default setting of 10 seconds.
NOTE
The mvr querytime command is relevant only in dynamic mode.
