Description
Use the ping command to verify whether the destination device in an IP network is reachable, and to
display the related statistics.
Note that:
You must use the command in the form of ping ip ip instead of ping ip if the destination name is a
key word, such as ip.
Only the directly connected segment address can be pinged if the outgoing interface is specified
with the -i argument.
Examples
# Check whether the device with an IP address of 10.1.1.5 is reachable.
<Sysname> ping 10.1.1.5
PING 10.1.1.5 : 56 data bytes, press CTRL_C to break
Reply from 10.1.1.5 : bytes=56 Sequence=1 ttl=255 time = 1 ms
Reply from 10.1.1.5 : bytes=56 Sequence=2 ttl=255 time = 2 ms
Reply from 10.1.1.5 : bytes=56 Sequence=3 ttl=255 time = 1 ms
Reply from 10.1.1.5 : bytes=56 Sequence=4 ttl=255 time = 3 ms
Reply from 10.1.1.5 : bytes=56 Sequence=5 ttl=255 time = 2 ms
--- 10.1.1.5 ping statistics ---
5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 1/2/3 ms
The above information indicates the following:
The destination host was reachable
All probe packets sent by the source device got responses
The minimum time, average time, and maximum time for the packet's roundtrip time are 1 ms, 2 ms,
and 3 ms respectively
