Configuration Parameters
This section describes each parameter in the Model 281xSA hub configuration
file 281sa100.cfg. To modify the file, use an ASCII text editor, such as the
Windows Notepad, to change parameter values or to add or delete parameters.
Parameter names are shown here in boldface. You must replace the
parameter arguments shown in italics with specific values. If multiple
arguments are shown separated by a vertical bar (|), you may enter any one of
the displayed values. (Note that this use of the vertical bar is different from its
use in BOOTPTAB.TXT to separate records.)
Dotted-decimal notation, used with the IP address values, takes the form
N.N.N.N, where N is a numeric value from 0 to 255 inclusive. Unlike IP
addresses in BOOTPTAB.TXT, N is always interpreted as a decimal number.
These are the configuration file parameters:
filename or drive:\directory\filename
The pathname and filename for the Model 281xSA hub image file. This
parameter must be the first uncommented line in the configuration file.
You may include the drive as part of the path.
netmask ip_address
The local subnet mask for this Model 281xSA hub—up to 12 numeric
characters in typical IP dotted-decimal notation. If no entry exists in the
configuration file, one of the following default addresses will be used
(depending on what class of IP address is defined for your network):
Default for class A IP address is 255.0.0.0
Default for class B IP address is 255.255.0.0
Default for class C IP address is 255.255.255.0
NOTE:
The parameter must begin in the first column; otherwise, the line is
ignored by the Model 281xSA hub.
CAUTION:
This parameter is mandatory. If you do not enter a valid filename
or c:\directory\filename, the Model 281xSA cannot boot and fails to operate.
