Hello, dear.
You can refer to the following instructions to upload the license.
Installing License Files in Batches by Using the WebLCT
Step 1 Save the license file package in .zip format on the PC where the WebLCT client is installed.
This package consists of license files and the XML file that contains the mapping between ESNs and license files. You are not required to decompress the package file.
Step 2 Log in to the WebLCT client as a super administrator, choose Start DC.

Step 3 On the DC client, choose NE License Management.

Step 4 In the navigation tree, choose NE License Maintenance.

Step 5 Click Synchronize NE Information. In the displayed Synchronize NE Information dialog box, select the NEs that need to be synchronized, and click OK.


NOTE
Before importing commercial licenses in batches, ensure that NE information is synchronized so that ESN IDs and NE names are automatically matched.
Step 6 Click the Load License File button. On the displayed page, select the license file and NEs. Click Finish.

NOTE
During NE matching, right-click an NE and choose to Select All, to select all NEs.

View the license loading progress under Execution Status in the displayed window. Click + to check whether the loading is successful.

Step 7 Query the license status and verify the license information.
To query license status, perform operations in step 5 and then perform the following operations.
1 In the navigation tree, choose License Information Query.
2 In the right pane, click Filter.
3 In the displayed Filter dialog box, click Select to select the NE of which license status is to be queried.
4 Click OK.
5 In the right pane of the window, check the record of this NE.
6 The value in License Status indicates the NE license status.
Click the Query button on the lower-left corner to query the detailed information about the loaded licenses. Check whether the loaded license is the correct one and check whether there are license-related alarms on the NE.

Thanks!
