This article contains information about configuring a Network Time Protocol (NTP) server on a NetScaler appliance.

Background

In the earlier releases of the NetScaler software, you need to manually edit multiple files from the shell prompt of the NetScaler appliance to configure an NTP server. The edited information for each file needs to be accurate. Some users feel this procedure to be bit confusing. This issue is addressed in NetScaler software releases 9.0 and later. In these releases, you can complete the required configuration from either GUI or the command line interface of the appliance.

Instructions

To configure an NTP server from the GUI of a NetScaler appliance, complete the following procedure:

1. Expand the System node.

2. Select NTP Servers node, as shown in the following screenshot:

   

   Note: If you have not configured NTP on the appliance, the NTP Servers page displays NTP Synchronization –OFF, as shown in the following screen shot:

   

3. Click Add. In the Create NTP Server dialog box, specify the following details:

   • In the NTP Server field, specify the IP address or the name of the NTP server.

   • In the Minimum Poll Interval field, specify the minimum number of seconds after which the NTP server must poll the NTP messages.

   • In the Maximum Poll Interval field, specify the maximum number of seconds after which the NTP server must poll the NTP messages, as shown in the following sample screen shot:

     

4. Click Create.

5. Click Close.

6. To enable the synchronization with the NTP server, click NTP Synchronization - OFF on the NTP Servers page. The NTP server synchronization is enabled and NTP Synchronization –OFF changes to NTP Synchronization – ON, as shown in the following screen shot:

   

To configure an NTP server similar to the preceding procedure from the command line interface of the appliance, run the following commands:

> show ntp sync
Status: Disabled
> add ntp server 10.102.16.17 -minpoll 6 -maxpoll 10
> enable ntp sync
