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
properties:
ˆ “802.1p QOS” on page 41
ˆ “Checksum Offload” on page 43
ˆ “Flow Control” on page 43
ˆ “Jumbo Mtu” on page 44
ˆ “Large Send Offload” on page 45
ˆ “Locally Administered Address” on page 46
Note
The following steps may be slightly different if the Classic Start
Menu is set.
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 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.
