Configuring IGMP Snooping and MVR
Note To use MVR, the switch must be running the LAN Base image.
This chapter describes how to configure Internet Group Management Protocol (IGMP) snooping on the
Catalyst 2960 and 2960-S switches, 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 standalone switch and a switch stack.
Note Stacking is supported only on Catalyst 2960-S switches running the LAN base image.
For complete syntax and usage information for the commands used in this chapter, see the switch

IP Command Reference, Volume 3 of 3:Multicast, Release 12.2 from the Cisco.com page under
