11- gNodeB Manually Backing up Configuration Data
GUI : is short for graphical user interface
MML: is short for man-machine language, it is a command mode on a U2020 client.
A. Make Sure that U2020 client and server are properly connected.
B. Ensure that U2020 Server Properly Communicates with gNodeBs
C. When you are using MML Command , The Configuration File corresponding to the Current NE Version will be downloading
And Configuration data can be manually backed up in either of the following modes:
In GUI mode: Configuration data of multiple NEs can be simultaneously backed up.
In MML command mode: Configuration data of a single NE can be uploaded to the FTP server for backup.
Procedure
a) In GUI mode : Backing up Configuration Data
On the main menu of the U2020 client, choose Maintenance > Backup Management > NE Backup. The NE Backup dialog box is displayed.
In the navigation tree in the left pane of the NE Backup window, select gNodeB. Then, select the gNodeB whose data is to be backed up in the navigation tree, as shown in
A. Choose multiple NEs for Backup
B. Click Backup.
1. In the displayed Confirm dialog box, click Yes.
The backup task is displayed in the lower part of the NE Backup dialog box.
If Status is completed, the task is complete. If Information is succeeded, the backup task is successfully executed, as shown in
b) In MML command mode : Backing up Configuration Data
A) On the main menu of the U2020 client, choose Maintenance > MML Command.
B) In the MML Command window, select NR and then select an NE from the navigation tree.
C) Multiple NEs of the Same Version can be selected at a time
D) Click yes After download is completed
2. On the right of the MML Command window, Run the BKP CFGFILE command to generate a backup file.
3. Run the ULD CFGFILE command to upload the backup file to the FTP server.
In this command:
A- Set FTP Server IP to the IP address of the U2020 server.
B- Set User Name to the FTP user name of the U2020 server ftpuser by default).
C- Set Password to the FTP password of the U2020 server (ftpuser by default).
PS:
1- While running downloading file we a must upload each file to a unique save Path
2- If the save Pathes are the same for NEs , An earlier back up file will be replaced by a later Backup file
3- You Can save the Path of Backup with the same of backup date e.g : C;/backup/20201011
4- After uploading completed , You use the FTP Client software to view the gNodeB Configuration file in the save Path
12- gNodeB Restoring Configuration Data
A - In GUI mode: Restoring Configuration Data
Perform the following operations if data needs to be restored:
1. On the main menu of the U2020 client, choose Maintenance > Backup Management > NE Backup.
2. Perform the following operations in the NE Backup dialog box:
a. From the navigation tree on the left, select BTS5900 or BTS5900 5G.
b. From the navigation tree, select the NE whose data needs to be restored.
c. In the NE Backup List area on the right, select a backup file, click Restore in the lower right area of NE Backup List.
B - In MML command mode: Restoring Configuration Data
Perform the following operations if data needs to be restored:
1. On the left of the MML Command window, select the NE whose data is to be restored.
2. On the right of this window, run the DLD CFGFILE command to download backup file to the NE.
3. After the download is complete, run the ACT CFGFILE command to activate the configuration file.
I hope that my post helps you , Thank you
