Switch Operation Overview

Address Table Operation

Address Learning. As devices are connected to the switch ports,
either directly or through hubs or other switches that are connected
to the switch, the MAC addresses of those devices are learned auto-
matically and stored in the Switch 408's 8000-entry address table. The
switch also identifies the number of the port on which each address
is learned so it knows the relative network location of each device.
