On the U2000 Web LCT, you can use the standard network time protocol (NTP) service to automatically synchronize the NE time with the standard NTP server time. To ensure that a reliable server is accessed, the NTP authentication function must be started. In this case, you need to set the key and password, which are authenticated together to check whether the server is reliable.
Procedure
- Choose from the main menu. Click Standard NTP Key Management tab.
- In the Object Tree, select one or more NEs and click the double-right-arrow button (red).
- Click Add and the Add Key and Password dialog box is displayed.
- Select the NE in the NE List pane, set Key and Password, and set Trusted to Yes. Then, click Apply.
NOTE: To ensure the security of the NMS, passwords must be complex enough. For example, a password must contain eight or more characters of two types. The allowed characters are digits, letters, and special characters. Remember to change passwords regularly.
- In the Operation Result dialog box displayed, click Close.
