Configuring IGMP Snooping and MVR
This chapter describes how to configure Internet Group Management Protocol (IGMP) snooping on your
Catalyst 2950 or Catalyst 2955 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.

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.
