To configure NTP on supported devices
Before you begin
NEs can act as NTP servers, clients, or peers.
The 7705 SAR acts as an NTP client as well as an NTP server. The 7705 SAR as an NTP server, and the support for NTP on a VPRN service is supported from Release 21.4 R1 and later.
Note: For the Wavence SM, if the main and spare NTP servers are defined with the same IP address in NEtO, only the IP address for the main server will be displayed in the NFM-P. Main and primary NTP servers with the same IP address should be avoided.
For any failed operation related to NTP server addition or modification, you must close the current GUI session on the NTP tab and reopen it before proceeding. This action removes the failed entry from the GUI cache so that it is not applied again.
The tabs and parameters that are configurable vary depending on the NE.
Steps
1 |
On the equipment tree, choose Network→NE where NE is the object on which you need to configure NTP. |
2 |
Right-click on the NE and choose Properties. The Network Element (Edit) form opens. |
3 |
If you are configuring a 7705 SAR, Release 6.2 R1 or earlier, or a Wavence SM, click on the NTP tab and configure the NTP State parameter, and go to Step 6 . If you are configuring a 7705 SAR, Release 7.0 or later, go to Step 4 . You must set the NTP State parameter to Enabled in order to configure the remaining NTP parameters. |
4 |
Configure the NTP State parameter on the General tab. You must set the NTP State parameter to Enabled in order to configure the remaining NTP parameters. When you change the NTP State parameter from Disabled to Enabled, you must click Apply and confirm the action in order to activate the NTP tab. |
5 |
Click on the NTP tab. The General tab is displayed. |
6 |
Configure the required parameters. |
