846 Configuring L2 Multicast Features
Configuring L2 Multicast Features (CLI)

This section provides information about the commands you use to configure

L2 multicast settings on the switch. For more information about the

commands, see the

Dell Networking N2000, N3000, and N4000 Series
Switches CLI Reference Guide

at support.dell.com/manuals. Because L3 IP

multicast (PIM/IGMP) utilizes a separate forwarding database from L2

multicast, it is recommended that L3 m ulticast features, including PIM and

IGMP, be disabled on L2 multicast enabled switches.
