Configuration Files; Approaches Of Software Maintenance For The Lsqm1Wcmb0 - H3C WIRELESSACCESSCOTROLLER S7500E Installation Manual

Note that:
Only the application files of the M, B, and S types can be used to boot the system, while an
application file of the N type (an application file other than the M, B, or S type) cannot.
After the application program is loaded, you can rename the application files through the CLI or
change the types of the M, B and N application files through the BootWare menu or the CLI.
However, you cannot change the type of the S application file.
As the S application file is the last choice for booting the system, you cannot change its type or
obtain it by changing the type of another type of application file. You can only download it using the
BootWare menu.
Only one file of the same type (M, B, or S) can exist in the CF card. For example, if an application
file of type M+B exists in the CF card, another file of type M or B cannot exist. If the type of another
file is changed to B, the existing type M+B file changes to a file of type M.

Configuration Files

With a file extension of .cfg, the configuration files store the configuration information of the
LSQM1WCMB0 access controller module. Typically, the default configuration file is written into the
built-in CF card before the access controller module is delivered.
The length of a configuration file name must not exceed 64 characters (including the drive name
and the string terminator). For example, if the drive name is cfa0:/, the maximum length of a file
name is [ 64 – 1 – 4 ] = 59 characters.
If the length of a file name exceeds 59 characters, error will occur in file operations on that file. It is
recommended to keep the file name within 16 characters.
There is a limitation on the length of file name that can be displayed in BootWare. If a file name is
shorter than 30 characters, all the characters of the file name can be displayed; if a file name has or
exceeds 30 characters, only the first 26 characters of the file name can be displayed, followed by a
tilde (~) and a serial number. The serial number identifies position in sequence of the file. For
example, if some files, file A, file B and file C, have a file name longer than 30 characters, the name
of file A will appear as the first 26 characters plus ~001, that of file B will appear as the first 26
characters plus ~002, and that of file C will appear as the first 26 characters plus ~003.
