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 multicast features, including PIM and
IGMP, be disabled on L2 multicast enabled switches.
