How to Troubleshoot Network Ping -T
Ping is a command-line utility used to measure the response time between two devices. This utility allows simple identification of a connection's consistency and overall quality. Multiple switches are included with this tool to allow you to control various aspects of the command. The "-T" switch allows the command to run continuously. By default, the Ping command will only send four requests. By using the "-T" switch, you can let the command run indefinitely while troubleshooting. This can serve several useful purposes. This also allows you to see if your troubleshooting procedures are having an effect in real-time.

Look at the "time" in each of the replies. Each of these lines provides the total measured time in milliseconds that it took for your packet to make a round trip. The lower the value, the faster the response time is between the two devices. If you happened to receive a "Ping request could not find host" or "Request timed out" message, the connection between the two devices has failed.

Press and hold the "Ctrl" and "C" keys consecutively to stop the Ping -- T command. This displays a group of statistics. The Sent, Received and Lost statistics are used for testing intermittency. The Sent statistic is the total amount of ping requests you ran before stopping the command. The Received statistic is how many were returned to you. If any packets failed to make their round trip, it will count as a Lost statistic. Ideally, the number next to Sent and Received should be the same, and the number next to Lost should be 0.

Look at the "Approximate round trip..." section, which is the last group of statistics. The Minimum statistic is the lowest response time you received out of all requests. The Maximum stat is the highest response time you received, and the Average is the calculated average of all requests.
