Fibre Channel Class
The Windows NT IP driver can operate in class 2, or 3, but is set to 3 (default) during
installation. To view or change this entry without directly modifying the registry, access the
LAN registry parameter window and make changes there.
A second method is to run the registry configurator program (lp6conf.exe) which came with
the Emulex Windows NT driver. After running configurator program, the system must be
rebooted.
You can also add or modify the class entry in the Windows NT registry as shown below.

loop (default) during installation.
