Configuring MVR
Configuring MVR
Beginning in privileged EXEC mode, follow these steps to configure MVR:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
mvr Enable MVR on the switch.
Step 3
mvr group ip-address [count] Configure an IP multicast address on the switch or use the count parameter
to configure a contiguous series of IP addresses. Any multicast data sent to
this address is sent to all source ports on the switch and all receiver ports that
have elected to receive data on that multicast address. Each multicast address
would correspond to one television channel.
Note Each IP address translates to a multicast 48-bit MAC address. If an
IP address being configured translates (aliases) to a previously
configured MAC address, the command fails.
Step 4
interface interface Enter interface configuration mode, and enter the type and number of the
port to configure, for example, fastethernet 0/1.
Step 5
mvr type value Configure the port as either an MVR receiver port or an MVR source port.
• 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 by using IGMP leave and join messages.
• Configure uplink ports that receive and send multicast data as source
ports. All source ports on a switch belong to the single multicast VLAN.
Step 6
mvr immediate (Optional) Enables the Immediate Leave feature of MVR on the port.
Note This command applies only to receiver ports and should only be
enabled on receiver ports to which a single receiver device is
connected.
Step 7
end Exit configuration mode.
Step 8
show mvr
show mvr interface
show mvr members
Verify the configuration.
Step 9
copy running-config startup-config Save your configuration changes to NVRAM.
