Link Speed & Duplex. Allows the user to set the connection speed to the network and mode. Full- Duplex Mode allows the adapter to transmit and receive network data simultaneously.

o Default = Auto Detect o Range

100 Mbps/Full-Duplex: Sets the speed at 100 Mbps and mode to Full-Duplex

100 Mbps/Half-Duplex: Sets the speed at 100 Mbps and mode to Half-Duplex

10 Mbps/Full-Duplex: Sets the speed at 10 Mbps and mode to Full-Duplex

10 Mbps/Half-Duplex: Sets the speed at 10 Mbps and mode to Half-Duplex

Auto Detect: Sets the speed and mode for optimum network connection

Locally Administered Address. Specifies the user-defined MAC Address of the adapter; overrides the burned-in MAC Address. This is a read-only field if the adapter is teamed.

o Default = Not Present

o Range = Value; Not Present

Receive Buffers. Specifies the number of buffers used by the driver when copying data to the protocol memory. In high network load situations, increasing receive buffers can increase performance. The tradeoff is that this also increases the amount of system memory used by the driver. If too few receive buffers are used, performance suffers. If too many receive buffers are used, the driver unnecessarily consumes memory resources.

o Default = 48

o Range = 8–1024 (increments of 1)

Transmit Control Blocks. Specifies the number of resources that are allocated to transmit packets. o Default = 16

o Range = 1–64

Modifying adapter properties in Windows NT

This document describes the Windows NT® 4.0 adapter properties available for fiber and copper server adapters.

Properties for 10/100 Copper Server Adapters

Speed/Duplex Setting. Changes the current speed and duplex settings. Be sure this setting is compatible with the link partner (examples: switch, hub).

o Default = Auto/Auto

o Range = 10/Half; 10/Full; 100/Half; 100/Full; Auto/Auto

NOTE: The NC3133 is a 100BASE-FX fiber optic upgrade module that supports 100 Mbps only.

Locally Administered Address. Specifies the user-defined MAC Address of the adapter, which overrides the burned-in MAC Address. This box is disabled if the selected adapter has been teamed.

o Default = NULL

o Range = Valid unicast MAC Address
