Autonegotiation
Autonegotiation means the automatic detection/negotiation of the transmission rate and the
operating mode of ports at the opposite end. This makes it possible to configure different
devices automatically.
Two components connected to a link segment can exchange information about the transfer
and can adapt their settings to each other. The mode with the highest possible speed is set.
Note
•
If a port operating in the "Auto negotiation" mode is connected to a partner port that is not
operating in the"Auto negotiation" mode, the partner port setting must be fixed.
• Devices not supporting "Auto negotiation" must be set permanently to 100 Mbps or
10 Mbps half duplex.
