4.0 OPERATION
This chapter describes the functions and operation of the 4K-Series.
4.1 Switching
Functionality
RFL 3000 4K-Series units provide switched connectivity at Ethernet wire-speed
among all of its ports simultaneously. They support 10/100Mbs for copper media and
100Mb for fiber ports to maximize bandwidth utilization and network performance. All
ports can communicate to all other ports in a RFL 3000 4K-Series, but local segment
traffic on a port will not consume any of the bandwidth on any other port.
RFL 3000 4K-Series units are plug-and-play devices. There is no software
configuring to be done at installation or for maintenance. The only hardware
configuration settings are user options for UP-LINK on RJ-45 port. The internal
functions of both are described below.
Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to
either filter or to forward the packet. Packets whose source and destination addresses are
