The length of a configuration file name must not exceed 64 characters (including the drive identifier
and the string terminator). For example, if the drive identifier is
flash: /
, the maximum length of a
file name is [ 64 – 1 – 5 ] = 58 characters.
z
If the length of a file name exceeds 58 characters, operations on that file will fail. It is recommended
to keep a file name within 16 characters.
z
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. This serial number identifies the position in sequence of the file. For
example, if 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.
Web Files
Web files are used by the switching engine to provide Web-based functions, and are released with
version releases (each version has a default Web file). You are not recommended to modify the file
name and settings.
Web files fall into main and backup files, and are managed like the application files on the access
control engine.
Approaches for Software Maintenance
You can maintain the device in either of the following two ways:
z
Update BootWare and application files using the XMODEM protocol through a serial port.
z
Update BootWare and application files using the TFTP/FTP protocol via an Ethernet port through
the BootWare menu or the CLI.
z
The BootWare program is updated together with the Comware application. When you update the
Comware application to the latest version, the BootWare is updated to the latest version
automatically.
z
Before updating the software, check the current version of BootWare and that of the application
program to make sure that the correct file is used for the update. For the association between the
host software version and the BootWare version, refer to the hardware and software compatibility
matrix in
