Auto-Negotiation
A key feature of the Sun Quad FastEthernet SBus 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 the
auto-sensing protocol selects the speed (10 Mbps or 100 Mbps) for the adapter.
The hme device driver operates the SUNW,hme devices by default in
half-duplex mode only. If the adapter is connected to an Ethernet switch or hub
that does not support auto-negotiation, the device driver will operate in
half-duplex mode.
If the Sun Quad FastEthernet SBus 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 Sun Quad FastEthernet SBus 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 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 AnswerBook.
