Example 7-2 shows ping returning three values separated with the slash “/,” the minimum, average, and
maximum RTT. Large differences in these values could indicate network congestion or a network
problem. In most cases, the average value accurately portrays the network latency to the destination. By
default, ping uses small packets for connectivity testing; the packet size will influence the RTT values.
The packet size may be changed in some implementations, including that of Cisco Systems's IOS.
