If no response packet is received within thetimeout time, the message "Request time out" is displayed. Otherwise, the numberof data bytes, packet serial number, TTL (time to live) and response time of theresponse packet are displayed.z Final statistics, including the numbers of sent packets and received responsepackets, the irresponsive packet percentage, and the minimum, average andmaximum values of response time.3.1.2 tracertYou can use the tracert command to trace the gateways a packet passes during itsjourney from the source to the destination. This command is mainly used to check thenetwork connectivity. It can help you locate the trouble spot of the network.The executing procedure of the tracert command is as follows: First, the source hostsends a data packet with the TTL of 1, and the first hop device returns an ICMP errormessage indicating that it cannot forward this packet because of TTL timeout. Then,
