5.5 Auto-Negotiation

The STP ports on the 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 detecting the
modes and speeds both connected devices are capable of. Both 10BASE-T and 100BASE-TX devices can connect with the
port in either half- or full-duplex mode. 1000BASE-T can be only connected in full-duplex mode.
