Chapter 28 Configuring IGMP Snooping and MVR
How to Configure IGMP Snooping and MVR
Configuring MVR Interfaces
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
mvr Enables MVR on the switch.
Step 3
mvr group ip-address [count] Configures 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.
Step 4
mvr querytime value (Optional) Defines 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.
Step 5
mvr vlan vlan-id (Optional) Specifies 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
4096. The default is VLAN 1.
Step 6
mvr mode {dynamic | compatible} (Optional) Specifies the MVR mode of operation:
• 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.
Step 7
end Returns to privileged EXEC mode.
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
mvr Enables MVR on the switch.
Step 3
interface interface-id Specifies the Layer 2 port to configure, and enters interface configuration
mode.
Step 4
mvr type {source | receiver} Configures an MVR port as one of these:
• source—Configures 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—Configures 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.
