until the test is stopped. Press the AutoTest  key to stop
the test.
When not in Continuous mode, the analyzer will send pings over
all enabled interfaces. Wired IPv4 and wired IPv6 pings run
simultaneously.
Don’t Fragment - When this option is On , the analyzer will set the
“don’t fragment” bit in the frame. The frame will not be split into
smaller frames when passing through switches and routers.
How it Works
The ping test sends echo request packets to a host and awaits
replies. Ping responses that do not return within the selected time
limit are considered lost.
The analyzer sends ICMP echo request packets to the target host
(the server) and waits for a response. The analyzer records the
response time and reports whether packet loss occurs. The
analyzer uses the ICMP protocol for IPv4 tests, and the ICMPv6
protocol for IPv6 tests.
Results
The results include the current ping response as well as overall
response statistics.
