4.1.1 Auto-negotiation
Auto-negotiation 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.
If attached device is:
100Base-TX port will set to:
10Mbps, no auto-negotiation
10Mbps.
10Mbps, with auto-negotiation
10/20Mbps (10Base-T/Full-Duplex)
100Mbps, no auto-negotiation
100Mbps
100Mbps, with auto-negotiation
100/200Mbps (100Base-TX/Full-Duplex)
