Configuring MVR Global Parameters

You do not need to set the optional MVR parameters if you choose to use the default settings. If you do
want to change the default parameters (except for the MVR VLAN), you must first enable MVR.
Beginning in privileged EXEC mode, follow these steps to configure MVR parameters:
Command
Step 1 configure terminal
Step 2
mvr
Step 3
mvr group ip-address [count]
Step 4
mvr querytime value
Step 5
mvr vlan vlan-id

shows the default MVR configuration.
Purpose
Enter global configuration mode.
Enable MVR on the switch.
Configure an IP multicast address on the switch or use the count parameter to
configure a contiguous series of MVR group addresses (the range for count is
1 to 256; the default is 1). 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.
Each IP address translates to a multicast 48-bit MAC address. If an IP
Note
address being configured translates (aliases) to a previously
configured MAC address or to any reserved multicast MAC
addresses, the command fails.
(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 1001.
The default is VLAN 1.
Default Setting
Disabled globally and per interface
