Configuring Layer 2 Multicast MVR Configuration
Step 5 mvr querytime
time
Specify the maximum time to wait for the IGMP membership reports since the switch receives
an IGMP leave message on a receiver port.
time:
Specify the maximum response time. After receiving an IGMP leave message from a
receiver port, the switch will send out group-specific queries and wait for IGMP membership
reports. If no IGMP membership reports are received before this configured time expires, the
switch will remove the port from the multicast group. Valid values are from 1 to100 tenths of a
second, and the default value is 5 tenths of a second.
Step 6 mvr group
ip-addr count
Add multicast groups to the MVR.
ip-addr:
Specify the start IP address of the contiguous series of multicast groups.
count:
Specify the number of the multicast groups to be added to the MVR. The range is 1 to
511.
Step 7 show mvr [ interface { fastEthernet
port
| gigabitEthernet
port
| port-channel
lagid
| ten-
gigabitEthernet
port
} [members { vlan
vlan-id
}]
Show the global MVR configuration.
show mvr members [
ip
] [status {inactive | active}]
Show the existing MVR groups.
ip
: Specify the IP address of the multicast group.
inactive: Show all inactive multicast group.
active: Show all active multicast group.
Step 8 end
Return to privileged EXEC mode.
Step 9 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to enable MVR globally, and configure the MVR mode
as compatible, the multicast VLAN as VLAN 2 and the query response time as 5 tenths of a
second. Then add 239.1.2.3-239.1.2.5 to MVR group.
Switch#configure
Switch(config)#mvr mode compatible
Switch(config)#mvr vlan 2
Switch(config)#mvr querytime 5
Switch(config)#mvr group 239.1.2.3 3
Switch(config)#show mvr
MVR :Enable
