DOS Diagnostic Failures

Linux
To verify that the Ethernet interface is up and running, run
ifconfig
to check the status of
the Ethernet interface. To check the statistics on the Ethernet interface, you can also use
netstat -i
. Consult manual pages for more information on
ifconfig
and
netstat
.
DOS Diagnostic Failures
Running the DOS diagnostic B57DIAG.exe can result in false failures under the following
circumstances:
■
The DOS diagnostic B57DIAG.exe will fail if EMM386.exe is loaded in low memory. Do
not use EMM386.exe when running the DOS diagnostic program.
■
When using the DOS diagnostic B57DIAG.exe for the fiber NIC (3C996-SX), you must
use the
-npol
option to pass all diagnostic tests. For example:
b57diag -npol
Omiting the
-npol
option causes the fiber NIC to fail each diagnostic test.
Wake-on-Lan
The fiber version of the Gigabit Server NIC will not operate with Wake-on-LAN (WOL). You
must disable WOL when using this version of the Gigabit Server NIC.
Known Problems
This section provides a list of known software problems and solutions for Windows 2000
and Linux.
Windows 2000
Problem Solution
Able to create LAC connections
icons having same name under
network properties menu.
Each network adapter installed properly will have an icon in Network Properties window. The
name of the icon is usually in the form of “Local Area Connection ##” and where ## is a number
starting from 1. The names of icon can be changed by right clicking the icon and selecting
rename. The name of the icon is only meaningful to the Network Properties window. Sometimes
the system administrators will rename these icons to easily differentiate the network
connections. When Advanced Server Features is configured, Advanced Server Features will create
additional adapter icons and rename the icons. The naming convention is to allow end users to
quickly identify the adapter with corresponding team and VLAN. The names of the icons created
by Advanced Server Features therefore are not recommended to be changed.
Uninstalling the Advanced Server
Features software and user is
prompted to reboot early.
After configuring Advanced Server Features team, the system may sometimes prompt user to
reboot. This is because Plug and Play may fail to commit any change in the network protocol
binding. Users can choose not to reboot and continue configuring intermediate driver without
having any side effect. When user has finished all the configuration, it is required to reboot.
Cannot enable VLAN after it is
disabled.
Advanced Server Features program creates additional network connections in “Network
Connection and Dial-up” Window. Similar to physical network connections, these virtual
connections can be disabled via the context menu. However, if these virtual connections are re-
enabled, the system will report error as “connection failed!”. This is known problem with
Windows 2000. When this happens, rebooting the system enables the virtual connection again.
Able to configure Internet
Connection Sharing (ICS) when
there aren't any unassigned
adapters.
Windows 2000 networking is shipped with the Internet Connection Sharing (ICS), which is
designed to allow multiple computers to access the Internet through a Windows 2000 system.
To configure ICS, a user would need to select a network connection as “outside” connection,
and another network connection as “inside” connection. 3Com has observed that ICS allows
any available network connection to be “outside” and “inside,” regardless of the Advanced
Server Features team configuration. 3Com recommends that the user not select any network
connection that is part of the Advanced Server Features team to be “outside” and “inside.”
