Configuring Mvr Interfaces - Cisco WS-C3750-48PS-S Software Configuration Manual

Chapter 23 Configuring IGMP Snooping and MVR
Command
Step 4 mvr querytime value
Step 5 mvr vlan vlan-id
Step 6 mvr mode {dynamic | compatible} (Optional) Specify the MVR mode of operation:
Step 7
end
Step 8 show mvr or show mvr members
Step 9 copy running-config
startup-config
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 group address, set the query time to 1 second
(10 tenths), specify the MVR multicast VLAN as VLAN 22, and set the MVR mode as dynamic:
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
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 Layer 2 MVR interfaces:
Command
Step 1 configure terminal
Step 2 mvr
Step 3
interface interface-id
78-16180-02
Purpose
(Optional) Define the maximum time to wait for IGMP report memberships
on a receiver port before removing the port from multicast group membership.
The value is in units of tenths of a second. The range is from 1 to 100 and the
default is 5 tenths or one-half second.
(Optional) Specify the VLAN in which multicast data is received; all source
ports must belong to this VLAN. The VLAN range is 1 to 4094.
The default is VLAN 1.
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.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enable MVR on the switch.
Enter interface configuration mode, and enter the type and number of the
Layer 2 port to configure.
