Time Extraction from the TODI Time Server Failed Due to Incorrect Route Parameter Settings

Publication Date:  2012-07-24 Views:  54 Downloads:  0
Issue Description
At an office, a new BOTS V3 time server was installed. The client was connected to the TODI network port through the DCN that was formed by routers. The client failed to obtain the time from the TODI.       
Alarm Information
None.      
Handling Process
1. Engineers connected the computer, instead of the time server and the client, directly to both the ends of the DCN. Both the ends could successfully ping each other. Therefore, the problem was not with the DCN.
2. Engineers checked the setting of the client in the NTP management of the time server, and found that the client IP address and the IP address of the TODI network port were in different netwok segments. Tthe client IP address was 10.147.69.25 and the IP address of the TODI network port was 10.149.68.38.
3. In this case, Route Parameters needed to be set.
4. The route parameters were set as follows:
IP address: 10.147.69.25
Mask: 255.255.255.0
Gateway IP address: 10.147.69.1
The TODI data was loaded. Then, the client can obtain the time from the time server, thus solving the problem.             
Root Cause
1. The DCN between the client and the time server might be faulty.
2. The time server used the NTP to manage the clients. The relevant settings might be faulty, for example, the client IP address might not be correctly added.
3. The settings of the route parameters of the TODI might be incorrect.        
Suggestions
If the client IP address and the IP address of the TODI network port are in the same network segment, Route Parameters need not be set.
If the client IP address and the IP address of the TODI network port are in different netwok segments, Route Parameters need to be set.
