Configuring IGMP Snooping and MVR
This chapter describes how to configure Internet Group Management Protocol (IGMP) sn ooping on your
Cisco Systems Intelligent Gigabit Ethernet Switch Module, 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.
Note For complete syntax and usage information for the commands used in this chapter, see the switch
command reference for this release and the Cisco IOS Release Ne twork Protocols Command Reference,
Part 1, for Cisco IOS Release 12.1

Note For MAC addresses that map to IP multicast groups, you can either manage them through features such
as IGMP snooping and MVR, or you can use static MAC addresses. However, you cannot use both
methods simultaneously. Therefore, before using IGMP snooping or MVR, you should remove all
statically configured MAC addresses that map to IP multicast groups.
