Fig. 7.12: ICMP Ping
Ping (Packet InterNet Groper) is a utility used to test the reachability of a particular host on an IP network.
It operates by sending echo request packets to the target host and waiting for an echo response. In
the process it measures the rtt (round trip time - the time from transmission to reception) and records
any packet loss.
The source IP address of Ping in RipEX is always the IP address of Ethernet interface (Settings/ETH/IP).
While using Ping, be sure that correct routing between source and destination IP addresses exists.
Also pinged device has to have ICMP echo response enabled. RipEX has the ICMP echo response
always enabled.
NOTE: Ping utility generates on-line report each 2 seconds while you are connected to Local unit and
each 10 sec. while it is generated from Remote unit and it is transferred over the Radio channel.
■ Ping Type
List box: ICMP, RSS
Default = RSS
ICMP
This is a standard ICMP (Internet Control Message Protocol) ping. It can be used against either
RipEX or any other IP device connected to RipEX Radio network.
RSS
RSS ping is a proprietary utility using UDP frames to trace the frame passing through the network
including radio hop RSS and DQ. Following values are measured and reported:
• RSS and DQ information for each radio hop for each individual ping
• RSS and DQ statistic (average, min., max.) for radio hop with the lowest RSS in both directions
• Histogram of rtt of pings divided to 5 intervals
• Load and Throughput
• PER (Packet Error Rate)
• BER (Bit Error Rate)
