Advanced Tab This section describes the Advanced tab, as shown in Figure 5
Figure 5. Advanced Tab
The Advanced tab contains the following fields:
ˆ 802.1p QOS. The 802.1p QOS property enables quality of service,
which is an Institute of Electrical and Electronics Engineering (IEEE)
specification that treats different types of network traffic differently to
ensure required levels or reliability and latency according to the type of
traffic. This property is disabled by default. Unless the network
infrastructure supports QoS, do not enable QoS. Otherwise, problems
may occur.
ˆ Checksum Offload. Normally the Checksum Offload function is
computed by the protocol stack. When you select one of the
Checksum Offload property values (other than None), the checksum
can be computed by the network adapter.
– Rx TCP/IP Checksum. Enables receive TCP, IP, and UDP
checksum offloading.
– Tx TCP/IP Checksum. Enables transmit TCP, IP, and UDP
checksum offloading.
– TX/Rx TCP/IP Checksum (default). Enables transmit and receive
TCP, IP, and UDP checksum offloading.
– None. Disables checksum offloading.
ˆ Ethernet@Wirespeed TM . The Ethernet@Wirespeed property enables
a Gigabit Ethernet adapter to establish a link at a lower speed when
only 2 pairs of wires are available in the cabling plant. By default, this
