Industrial Ethernet OSM/ESM Network Management

2.1 Autonegotiation
In the autonegotiation mode, an electrical OSM/ESM port sets itself automatically
to the transmission rate (10/100 Mbps) of the connected partner device. If the
partner device also supports autonegotiation, the devices further negotiate whether
they will exchange data in the half-duplex or full-duplex mode and full-duplex flow
control.
Note
If an OSM/ESM port that supports the autonegotiation mode is connected to a
partner that does not support this mode, the port of the partner device must be set
to the half-duplex mode.
