3.6.5 Auto-Negotiation
A key feature of the SunFastEthernet Adapter is auto-negotiation. The auto-
negotiation protocol, as specified by the 100BASE-T standard, automatically
selects the operation mode (half-duplex or full-duplex) and speed (10 Mbps or
100 Mbps) for the adapter.
The hme device driver operates the SUNW,hme device by default in half-duplex
mode only.
If the SunFastEthernet Adapter is connected to a remote system or interface
that is not capable of auto-negotiation, your system automatically selects the
speed and half-duplex mode.
If the SunFastEthernet Adapter is connected to a link partner with which the
auto-negotiation protocol fails to operate successfully, you can configure the
device to not use this protocol and force the driver to set up the link in the
mode and speed of your choice.
Refer to the Platform Notes: The hme Fast Ethernet Device Driver document (Part
No: 802-5333) for more information on the
hme device driver and auto-
negotiation. This document is also available on the Solaris 2.5 and the Solaris
2.5: 1/96 AnswerBook.
