To view GTL license-controlled features, use the Text Editor to open the GTL license file. The
contents in the Resource and Function fields are the resource and function items controlled by
the GTL license file.
Step 3 Obtain software required for the upgrade. The new system software (.cc file) and relevant
documents for the upgrade must be obtained from Huawei.
Step 4 In the user view, run the display version command to view the current system software. If the
current system software is the same as or later than new system software, the software upgraded
is not needed.
Step 5 Run the following commands to check the device operation status:
Run the display memory-usage command in the user view to check the memory usage of MPUs
to ensure that the MPUs are working properly.
Run the display health command in the user view and record the command output. If you cannot
locate faults that have occurred during the upgrade, provide the information to Huawei technical
personnel for troubleshooting.
Step 6 Set up an environment where software upgrade can be performed by means of TFTP or FTP.
This helps to back up the original resource files before the upgrade and upload the new resource
files required for the upgrade.
When the system software is upgraded by means of FTP:
l If the device to be upgraded functions as a client and a PC functions as a server, you need to
install the FTP server software on the PC. You need to purchase and install the FTP server
software yourself, because the device is not installed with such software by default.
l If the device to be upgraded functions as a server and a PC functions as a client, you do not
need to install the FTP server software on the PC. By default, the FTP server function on the
device to be upgraded is disabled. To enable the function, run the ftp server enable
command.
When the system software is upgraded by means of TFTP, the device to be upgraded can only
function as a client and does not provide the TFTP server function. In this case, you must install
the TFTP server software on the PC.
Step 7 Back up the important data stored in the storage media on the device to be upgraded.
Step 8 Check the remaining space of the storage media to make sure that there is enough space to store
the new system software and related upgrade files.
