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
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.
