Configuring IGMP Snooping and MVR
This chapter describes how to configure Internet Group Management Protocol (IGMP) snooping on the
Catalyst 3750-X or 3560-X switch, including an application of local IGMP snooping, Multicast VLAN
Registration (MVR). It also includes procedures for controlling multicast group membership by using
IGMP filtering and procedures for configuring the IGMP throttling action. Unless otherwise noted, the
term switch refers to a Catalyst 3750-X or 3560-X standalone switch and to a Catalyst 3750-X switch
stack.
Note For IP Version 6 (IPv6) traffic, Multicast Listener Discovery (MLD) snooping performs the same
function as IGMP snooping for IPv4 traffic. For information about MLD snooping, see Chapter 1,
“Configuring IPv6 MLD Snooping.”
Note For complete syntax and usage information for the commands used in this chapter, see the switch
command reference for this release and the “IP Multicast Routing Commands” section in the Cisco IOS
IP Command Reference, Volume 3 of 3:Multicast, Release 12.4.
This chapter consists of these sections:
• Understanding IGMP Snooping, page 1-2
• Configuring IGMP Snooping, page 1-7
• Displaying IGMP Snooping Information, page 1-16
• Understanding Multicast VLAN Registration, page 1-17
• Configuring MVR, page 1-20
• Displaying MVR Information, page 1-23
• Configuring IGMP Filtering and Throttling, page 1-24

Note You can either manage IP multicast group addresses through features such as IGMP snooping and MVR,
or you can use static IP addresses.
