AT-2500 Adapter Card Properties

Speed/Duplex

Network Address

EarlyTxThreshold


Speed/Duplex

The speed/duplex parameter can either be controlled by the adapter-card hardware or by the driver.
This parameter allows the driver to override the hardware setting. If you change this setting,
ensure that the hardware is in AUTO/NWAY mode. The hardware setting is accessible
through the setup25 utility.

Hardware — Adapter card hardware setting in effect

Auto — Enable 802.3u autonegotiation

10 Half Duplex — Force port to 10 megabits per second, half duplex

10 Full Duplex — Force port to 10 megabits per second, full duplex

100 Half Duplex — Force port to 100 megabits per second, half duplex

100 Full Duplex — Force port to 100 megabits per second, full duplex


Network Address

This property is used for applications where the preprogrammed media
access control (MAC) address must be overridden. To preserve the
original factory-set MAC address, click Skip. To enter an alternate MAC
address, type a 12-digit hexadecimal number and click OK. To revert to
the original MAC address, enter twelve zeros in this field and click OK.


EarlyTxTheshold

The AT-2500 is capable of starting to transmit a packet before it is
completely transferred from memory. This number determines how much
data must be transferred before transmission begins. Adjust this parameter
upward to reduce collisions or fragments observed or downward to increase
throughput. The default range is 9 to14.
