4.3 Fast Ethernet
100Base-TX and 100Base-FX are called "Fast Ethernet." This
is because they use the Ethernet CSMA/CD access rules and
data packet structure, but data travels ten times faster
(100Mbps) than traditional 10Mbps Ethernet.
Below is a list of the cable types and connectors that supported
by Fast Ethernet
Switch models for 10Base-T , 100Base-TX, and
100Base-FX networks.
PORT TYPE Cables Type Connector
100B ASE -TX Cat. 5 UTP only RJ-45
10B ASE -T Cat.3, 4, 5 UTP RJ-45

In many cases, 10Base-T LANs can quickly and easily upgrade
to 100Base-TX networks.
4.4 Auto-Negotiation
The 100Base-TX ports on the Fast Ethernet Switch have
built-in "Auto-Negotiation". This technology automatically sets
the best possible bandwidth when a connection is established
with another network device (usually at Power On or Reset).
This is done by detect the mode and speed at the second de-
vice is capable of. The 100Base-TX devices can connect with
the 100Base-TX port in either Half- or Full-Duplex mode.
If attached device is: 100Base-TX port will set to:
100Mbps, no auto-negotiation 100Mbps
(100Base-TX, Half-Duplex)
100Mbps, with auto-negotiation 200Mbps
(100Base-TX, Full-Duplex)
10Mbps, no auto-negotiation 10Mbps
(10Base-T, Half-Duplex)
10Mbps, with auto-negotiation 20Mbps
(10Base-T, Full-Duplex)
