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.
Note For complete syntax and usage information for the commands used in this section, see the command
reference for this release.
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
end
Step 8 show mvr or show mvr members
Step 9 copy running-config
startup-config
Cisco IE 3000 Switch Software Configuration Guide
21-20
Because MVR on the switch uses IP multicast addresses instead of MAC multicast addresses,
aliased IP multicast addresses are allowed on the switch. However, if the switch is interoperating
with Catalyst 3550 or Catalyst 3500 XL switches, you should not configure IP addresses that alias
between themselves or with the reserved IP multicast addresses (in the range 224.0.0.xxx).
MVR can coexist with IGMP snooping on a switch.
MVR data received on an MVR receiver port is not forwarded to MVR source ports.
MVR does not support IGMPv3 messages.
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.
(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 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 and 1006 to
4094. The default is VLAN 1.
• dynamic—Allows dynamic MVR membership on source ports.
• compatible—Is compatible with Catalyst 3500 XL and Catalyst 2900 XL
switches and does not support IGMP dynamic joins on source ports.
The default is compatible mode.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
