■ Destination
Default = 127.0.0.1
Destination IP address
■ Length [bytes]
Default = 80
The length of user data, the range from 8 to 4096 Byte. Some overhead to this Length is always
added like these:
ICMP - 28 bytes
RSS - 43 bytes for IP+UDP+RACOM header + 8 bytes (Trace-RSS and DQ) per each radio hop +
4 bytes (marking in server)
RSS ping can not be longer than 3/4 MTU.
■ Count
Default = 5
Number of pings to be transmitted. The allowed range is from 1 to 1024.
■ Period [ms]
Default = 1000
When this Period expires, the next Ping is transmitted. The range is from 1000 (1 sec.) to 3600000
(1 hour).
■ Timeout [ms]
Default = 10000
Timeout from 1000 (1 sec.) to 3600000 (1 hour).
When ping (the response) is not received within this timeout, it is counted as lost.
A short report is generated in run-time for each individual ping packet. When the Ping utility is
stopped, an overall statistic report is displayed.
■ ICMP Ping report
Standard Linux ping reports are provided, see Fig. 7.12, “ICMP Ping”:
Run-time report:
88 bytes from 192.168.141.215: icmp_req=1 ttl=63 time=413 ms
88 bytes total packet length
192.168.141.215 destination IP
icmp_req=1 ping sequence number
ttl=63 time to live, max. number of hops (passing through router)
of the packet in the network
time=413 ms rtt (round trip time), the time from transmission of ICMP echo
request to reception of ICMP echo response
Statistic report:
5 packets transmitted, 5 received, 0% packet loss, time 4005ms
rtt min/avg/max/mdev = 358.988/391.840/413.061/21.665 ms
time 4005ms total time of ping utility (from Start to Stop buttons)
