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
Step 6
mvr mode {dynamic | compatible} (Optional) Specify the MVR mode of operation:
Step 7

Catalyst 2950 Desktop Switch Software Configuration Guide
16-14
Default Setting
1
0.5 second
VLAN 1
Compatibility
Neither a receiver or source port
Disabled on all ports
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 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
corresponds 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 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 default is 5 tenths or one-half
a 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 when the
enhanced software image is installed and 1 to 1005 when the standard
software image is installed. Do not enter leading zeros. The default is
VLAN 1.
• dynamic allows dynamic MVR membership on source ports.
• compatible provides for compatibility with Catalyst 2900 XL and
Catalyst 3500 XL switches and does not support IGMP dynamic joins on
source ports.
The default is compatible mode.
Exit configuration mode.
