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

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

"Configuring IPv6 MLD Snooping."

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.
