Sample Task—Ping Host

Figure 69 shows a sample Ping Host page. In this example, you are sending ping requests are sent to two destination hosts—10.10.2.2 and 2.2.2.2. The echo requests reaches 10.10.2.2 and does not reach 2.2.2.2.

Figure 70 displays the results of a successful ping in the main pane, and Table 236 provides a summary of the ping host results and output.

Table 236: J-Web Ping Host Results and Output Summary

Ping Host Result	Description
64 bytes from	Size of ping response packet, which is equal to the default value in the Packet Size box (56), plus 8.
10.10.2.2	IP address of the destination host that sent the ping response packet.
icmp_seq=number	Sequence numbers of packets from 0 through 9. You can use this value to match the ping response to the corresponding ping request.
ttl=56	Time-to-live hop-count value of the ping response packet.
100.834 ms	Total time between the sending of the ping request packet and the receiving of the ping response packet, in milliseconds. This value is also called round-trip time.
10 packets transmitted, 10 packets received, 0% packet loss	Ping packets transmitted, received, and lost. 10 ping requests (probes) were sent to the host, and 10 ping responses were received from the host. No packets were lost.
100.215/104.397/120.158/7.831 ms	100.215—Minimum round-trip time 104.397—Average round-trip time 120.158—Maximum round-trip time 7.831—Standard deviation of the round-trip times ms—milliseconds

Figure 71 shows the output of an unsuccessful ping. There can be different reasons for an unsuccessful ping. This result shows that the local router did not have a route to the host 2.2.2.2 and thus could not reach it.
