Overview
Shows how to configure a custom NTP server in the Catalyst Center ARM template using a text editor.
Use this procedure to configure a custom Network Time Protocol (NTP) server for your Catalyst Center on Azure deployment.
When Catalyst Center on Azure is deployed using the ARM template, the default NTP server for time synchronization is the Azure cloud NTP server at IP address 168.61.215.74.
Before you begin
The NTP server configuration plays a critical role during the initial configuration and ongoing functionality of the system. So, the custom NTP server must be reachable and meet these requirements:
-
The NTP server must be low stratum, no more than four.
-
Jitter and offset must not exceed these maximum values:
-
Maximum offset: 500 ms
-
Maximum jitter: 299 ms
-
You also must contact your Cisco sales representative to request the required files for this release.
Procedure
| 1. | Open the downloaded file for the Catalyst Center ARM template in a text editor. |
|
| 2. | Search for lines 123 and 124.
|
|
| 3. | Search for the NTP server property in each line. Enter the custom IP address instead of the default IP address 168.61.215.74. You must keep the existing format, including the double quotes. For example, in this figure, you would need to replace the existing NTP IP address with the required value. Do not make any other modifications. 
|
|
| 4. | Save the updated file locally. |
The Catalyst Center ARM template is updated with the custom NTP server configuration.
