Modifying Configuration Properties
Although the default values are appropriate in most cases, you can
change any of the available options to meet the requirements of your
system. After the adapter driver software has been installed, you can use
this procedure to verify or change the following adapter properties:
“Large Send Offload” on page 57
“Locally Administered Address” on page 58
“Speed and Duplex Mode” on page 59
“Wake Up Capabilities” on page 61
Note
The procedures in the following sections may differ slightly if the
“Classic Start Menu” is set on your computer.
802.1p QOS
The 802.1p QOS property is a standard that enables the Quality of Service
(QOS) feature. It is responsible for the QOS provisions on the local
segment, and the avoidance of the "all packets are treated equally" issue,
which falls onto the hub or switch servicing segment. 802.1p QOS
provides prioritization of packets traversing a subnet. Thus, when the local
segment becomes congested and the hub or switch workload results in the
delaying or dropping packets, those packets with flags that correspond to
higher priorities receive preferential treatment and are serviced before
packets with lower priorities.
Note
You must have Administrator privileges to update the driver
software.
To enable or disable the 802.1p QOS property, perform the following
procedure:
1. Start either a Windows Server 2003 system or a Windows XP system
and log in.
2. On the desktop, right click My Computer and select “Properties.”
The System Properties dialog box opens, as shown in Figure 22 on
page 48.
