Using the CLI Commands
Each Echo Request includes a timestamp if the number of data bytes is greater than eight. This
timestamp calculates the round-trip time and is returned unchanged in the Echo Response. The
default packet size is 64 bytes, 56 of which are data and 8 are header. You can change the number
of data bytes using the databytes argument.
Unless issued with the –t option or the count argument, ping continually sends one request per
second, and displays a line of output for every response. Entering any character from the keyboard
stops ping. The count argument allows you to send a limited number of requests. When ping stops,
it displays a brief summary.
The following is a sample ping display, which the user stops by entering a keyboard character; the
PING Statistics appear after the character is entered.
annex# ping caddy
PING caddy: 56 data bytes
64 bytes from 132.245.6.25: icmp_seq=0. time=37. ms
64 bytes from 132.245.6.25: icmp_seq=1. time=12. ms
64 bytes from 132.245.6.25: icmp_seq=2. time=12. ms
64 bytes from 132.245.6.25: icmp_seq=3. time=12. ms
---- caddy PING Statistics ----
4 packets transmitted, 4 packets received, 0% packet loss
round-trip (ms) min/avg/max = 12/20/37
The following is a sample ping display for a host that does not answer, which the user stops by
entering a keyboard character; the PING Statistics appear after the character is entered.
annex# ping zinc
PING zinc: 56 bytes of data
---- zinc PING Statistics ----
15 packets transmitted,0 packets received, 100% packet loss
If zinc (in the previous example) is on another network, ping displays the following:
annex# ping zinc
PING zinc: 56 bytes of data
---- zinc PING Statistics ----
Host is unreachable... Received from 132.254.55.11
annex#
In the preceding example, 132.254.55.11 is the router connecting the local network to other
networks.
