Enabling packet forwarding
NOTE: These commands apply only to the 200 Series and 400 Series.
If you want to use layer-3 interfaces and IGMP snooping on certain FortiSwitch models, you must enable the forwarding of reserved multicast packets and IPv6 neighbor-discovery packets to the CPU. These features are enabled by default.
config switch global
set reserved-mcast-to-cpu {enable | disable}
set neighbor-discovery-to-cpu {enable | disable}
end
