Modifying Configuration Properties
Although the default values should be appropriate in most cases, you can
change any of the available options to meet the requirements of your
specific system. After the adapter driver software has been installed, you
can use this procedure to verify or change the following adapter

802.1p QOS
The 802.1p QOS property is a standard that enables Quality of Service
(QOS). 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 delay
(dropping) of packets, those packets with flags that correspond to higher
priorities receive preferential treatment and are serviced before packets
with lower priorities.
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.
You must have Administrator privileges to update the driver software.
2. On the desktop, right click My Computer.
The My Computer window opens.
3. Select Properties from the menu.
The System Properties dialog box opens, as shown in Figure 7 on
page 36.
