5.5 Auto-Negotiation

The STP ports on the Switch have a 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 when both devices are connected. Both 10BASE-T and 100BASE-TX devices can connect with the port in
either half- or full-duplex mode.
If attached device is:
10Mbps, without auto-negotiation
10Mbps, with auto-negotiation
100Mbps, without auto-negotiation
100Mbps, with auto-negotiation
100BASE-TX port will set to:
10Mbps.
10/20Mbps (10BASE-T/full-duplex)
100Mbps
100/200Mbps (100BASE-TX/full-duplex)
