1   Description

This instruction describes how to change the Network Time Protocol (NTP) server address.

The procedure consists of the following main steps:

1. Perform backups of the current system configuration
2. Change an NTP server address
3. Perform backups of the new system configuration

2   Procedure

2.1   Change NTP Server Address

Prerequisites

• This instruction references the following document:
  • Export Backup
• No tools are required.
• The following conditions must apply:
  • No other Backup and Restore Framework (BRF) backup operation is in progress.
  • The NTP server ID to change is known, for example, NTPServer1.
  • The new NTP server address is known.
  • userLabel text for the new NTP server is known.
  • An Ericsson Command-Line Interface (ECLI) session is in progress.

Steps

1. Navigate to the BrmBackupManager Managed Object (MO), for example:

   >dn ManagedElement=NODE06ST,SystemFunctions=1,BrM=1,BrmBackupManager=SYSTEM_DATA

2. Start the software backup operation, for example:

   (BrmBackupManager=SYSTEM_DATA)>createBackup B4NTPChange

   Note:  

   The backup name can have up to 50 characters. Alphanumeric, dash, and underscore characters are supported.

   
   

   The system returns output true or false.

3. Verify that the backup was created:

   (BrmBackupManager=SYSTEM_DATA)>show progressReport

   Note:  

   As this is a long-running operation, it can be necessary to enter the command several times until the final operation result is shown in the progress report.

   
   

   After a backup is successfully created, the progress report shows, for example, the following:

   progressReport actionId=0 actionName="CREATE" additionalInfo "Create Backup for B4NTPChange: Initialized" "Create Backup for B4NTPChange: Succeeded" progressInfo="" progressPercentage=100 result=SUCCESS resultInfo="B4NTPChange was created successfully." state=FINISHED timeActionCompleted="2015-12-15T10:44:41" timeActionStarted="2015-12-15T10:42:37" timeOfLastStatusUpdate="2015-12-15T10:44:41"

   Note:  

   To free up storage space, and for increased safety, export the backup to a different location; refer to Export Backup.

   
   
4. Navigate to the NtpServer MO, for example:

   >dn ManagedElement=NODE06ST,SystemFunctions=1,SysM=1,TimeM=1,Ntp=1,NtpServer=NTPserver1

   Note:  

   Press the Tab key twice at NtpServer= to list the current NtpServer MOs.

   
   
5. List the current settings:

   (NtpServer=NTPserver1)>show -v

   The following is an example output:

   NtpServer=NTPserver1 administrativeState=UNLOCKED ntpServerId="NTPserver1" serverAddress="100.0.12.13" userLabel="Primary NTP server"

6. Enter Config mode:

   (NtpServer=NTPserver1)>configure

7. Set the new NTP server address, for example:

   (config-NtpServer=NTPserver1)>serverAddress="100.0.12.14"

8. Set the attribute userLabel, for example:

   (config-NtpServer=NTPserver1)>userLabel="Primary NTP Server for application use"

9. Commit the setting:
   Attention!

   Risk of system malfunction or traffic disturbance.

   Connection to the NTP server is lost during the transition to the new NTP server address.

   (config-NtpServer=NTPserver1)>commit

10. Verify the changed NTP settings:

    (NtpServer=NTPserver1)>show -v

    The following is an example output:

    NtpServer=NTPserver1 administrativeState=UNLOCKED ntpServerId="NTPserver1" serverAddress="100.0.12.14" userLabel="Primary NTP Server for application use"

11. Navigate to the BrmBackupManager MO, for example:

    >dn ManagedElement=NODE06ST,SystemFunctions=1,BrM=1,BrmBackupManager=SYSTEM_DATA

12. Start the software backup operation, for example:

    (BrmBackupManager=SYSTEM_DATA)>createBackup AfterNTPChange

    Note:  

    The backup name can have up to 50 characters. Alphanumeric, dash, and underscore characters are supported.

    
    

    The system returns output true or false.

13. Verify that the backup was created:

    (BrmBackupManager=SYSTEM_DATA)>show progressReport

    Note:  

    As this is a long-running operation, it can be necessary to enter the command several times until the final operation result is shown in the progress report.

    
    

    After a backup is successfully created, the progress report shows the following:

    progressReport actionId=0 actionName="CREATE" additionalInfo "Create Backup for AfterNTPChange: Initialized" "Create Backup for AfterNTPChange: Succeeded" progressInfo="" progressPercentage=100 result=SUCCESS resultInfo="AfterNTPChange was created successfully." state=FINISHED timeActionCompleted="2015-12-15T10:54:14" timeActionStarted="2015-12-15T10:52:37" timeOfLastStatusUpdate="2015-12-15T10:54:14"

    Note:  

    To free up storage space, and for increased safety, export the backup to a different location; refer to Export Backup.
