Configuring Mvr Interfaces - Cisco Catalyst 3550 series Software Configuration Manual

Configuring MVR
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 Layer 2 MVR interfaces:
Command
Step 1
configure terminal
Step 2 mvr
Step 3 interface interface-id
Step 4
mvr type {source | receiver}
Step 5 mvr vlan vlan-id group ip-address

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; for example, enter gi0/1 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.
The default configuration is as a non-MVR port. If you attempt to configure
a non-MVR port with MVR characteristics, the operation fails.
(Optional) Statically configure a port to receive multicast traffic sent to the
multicast VLAN and the IP multicast address. A port statically configured as
a member of a group remains a member of the group until statically removed.
Note In compatible mode, this command applies to only receiver ports. In
dynamic mode, it applies to receiver ports and source ports.
Receiver ports can also dynamically join multicast groups by using IGMP
join and leave messages.
