round-trip min/avg/max/std-dev = 1.963/2.028/2.137/0.062 ms
The output shows that IP address 1.1.2.2 is reachable and the echo replies are all returned from the
destination. The minimum, average, maximum, and standard deviation roundtrip intervals are 1.963
millisecond, 2.028 milliseconds, 2.137 milliseconds, and 0.062 milliseconds, respectively.

Examples
# Ping IPv6 address 2001::2.
<Sysname> ping ipv6 2001::2
Ping6(56 data bytes) 2001::1 --> 2001::2, press CTRL_C to break

round-trip min/avg/max/std-dev = 4.000/25.000/62.000/20.000 ms
The output shows that IPv6 address 2001::2 is reachable and the echo replies are all returned from
the destination. The minimum, average, maximum, and standard deviation round trip intervals are 4
milliseconds , 25 milliseconds, 62 milliseconds, and 20 milliseconds, respectively.
