Chapter 11 Configuring IGMP Snooping and MVR
Configuring MVR
To return the switch to its default settings, use the no mvr [mode | group ip-address | querytime | vlan]
global configuration commands.
This example shows how to enable MVR, configure the MVR group address, set the query time to
1 second (10 tenths), specify the MVR multicast VLAN as VLAN 22, set the MVR mode as dynamic,
and verify the results:
Switch(config)# mvr
Switch(config)# mvr group 228.1.23.4
Switch(config)# mvr querytime 10
Switch(config)# mvr vlan 22
Switch(config)# mvr mode dynamic
Switch(config)# end
Switch# show mvr
MVR Running: TRUE
MVR multicast vlan: 22
MVR Max Multicast Groups: 256
MVR Current multicast groups: 1
MVR Global query response time: 10 (tenths of sec)
MVR Mode: dynamic
You can use the show mvr members privileged EXEC command to verify the MVR multicast group
addresses on the switch.
Configuring MVR Interfaces
Beginning in privileged EXEC mode, follow these steps to configure MVR interfaces:
Step 6
mvr mode {dynamic | compatible} (Optional) Specify the MVR mode of operation:
•
dynamic—Allows dynamic MVR membership on source ports.
•
compatible—Is compatible with Catalyst 3500 XL and Catalyst 2900 XL
switches and does not support IGMP dynamic joins on source ports.
The default is compatible mode.
Step 7
end
Return to privileged EXEC mode.
Step 8
show mvr
or
show mvr members
Verify the configuration.
Step 9
copy running-config
startup-config
(Optional) Save your entries in the configuration file.

Enable MVR on the switch.
Step 3
interface interface-id
Enter interface configuration mode, and enter the type and number of the port
to configure, for example, gi0/1 or gigabitethernet 0/1 for Gigabit Ethernet
port 1.
