Configuring Mvr Interfaces - Cisco Catalyst 2950 Software Configuration Manual

Chapter 16 Configuring IGMP Snooping and MVR
Command
Step 8
show mvr
show mvr members
Step 9
copy running-config
startup-config
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: 256
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:
Command
Step 1 configure terminal
Step 2
mvr
Step 3
interface interface-id
Step 4
mvr type {source | receiver}
78-11380-04
Purpose
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 port
to configure, for example, gi 0/1 or gigabitethernet 0/1 for Gigabit Ethernet
port 1.
Configure an MVR port as one of these:
• source—Configure uplink ports that receive and send multicast data as
source ports. Subscribers cannot be directly connected to source ports.
All source ports on a switch belong to the single multicast VLAN.
receiver—Configure a port as a receiver port if it is a subscriber port and
•
should only receive multicast data. It does not receive data unless it
becomes a member of the multicast group, either statically or by using
IGMP leave and join messages. Receiver ports cannot belong to the
multicast VLAN.
