network.
IP Multicast Filtering
A process whereby this switch can pass multicast traffic along to
participating hosts.

related directly to the hardware interface for network devices and passes
on traffic based on MAC addresses.
Layer 3
Network layer in the ISO 7-Layer Data Communications Protocol. This
layer handles the routing functions for data moving from one open system
to another.
