TFTP Configuration Data Requirements
The following information lists the configuration field and the required
character string that precedes the user configuration value that has been
chosen. Each configuration field data text string entry must be separated
from the previous and the following by new line character sequence, i.e.,
carriage return (0x0D hex) or carriage return/linefeed (0x0D 0x0A hex)
character combination. Without this delineation, the configuration of the
fields will not occur. The general format of these configuration field strings is:
FIELD IDENTIFIER = VALUE
Where FIELD IDENTIFIER is specified to the left of the = (or: which is also
allowed) followed by the VALUE.
For example, if you wanted to change the baud rate to 9600:
BAUD = 9600
Text strings must be surrounded by double quotes!
For example if you want port 7 to be designated ‘computer room’ then:
PORT NAME = 7 “COMPUTER ROOM”
BAUD = 9600
If the FIELD is multi-dimensional such as PORT_NAME (which has up to 16
ports), use the designating number followed by “=” and then the value.
For example:
PORT NAME [1] = “Port Number 1”
or
ELAN NAME [2] = “Elan Two”
One, or all, configuration fields can be used in a TFTP configuration file for
downloading purposes. When a given configuration file is not to be
downloaded, the default or previously entered configuration data for that field
will remain active.
Text strings require the double quote (“”) character. When a character string
is to be removed, enter a NULL STRING. A NULL STRING is defined as
two consecutive double quotes (“”) which will be interpreted as a string
length of zero.
In the configuration field examples that follow, there are numerous fields that
do not have double quotes around the value that is to be entered. These are
“defined” as constant fields. The allowable constant values are listed for each
field. The use of quotes around the constant value will cause this field setting
to be ignored.
An image file uses a binary format. Configuration data uses an ASCII format.
The switch, however, has the ability to differentiate between the two formats
and, once differentiated, accepts and places this data in the correct place.
