Ping (ICMP) Test

Ping (ICMP) Test
Purpose
Ping sends ICMP echo requests to the selected target to
determine whether the server or client can be reached. The target
can be an IPv4 address, IPv6 address or named server (URL or
DNS).
Configuration
Server - Enter the IP address or the name of the server you want
to ping. If you enter an IP address, the DNS lookup portion of the
test will be skipped.
Name - The Name button allows you to assign a custom name to
the test. The test’s name appears under the test’s icon on the
HOME screen and in OneTouch Reports. For your convenience,
the OneTouch analyzer automatically names the test based on
the URL or IP address. Tap the
Name button if you want to change
the name.
Frame Size - This specifies the total size of the payload and the
header to be sent. Valid sizes are 78 bytes to 9600 bytes.
To test the MTU along a route to a target, select the MTU frame
size you want to test and set
Don’t Fragment to On .
Pass on Test Failure - This feature causes the test to display a Pass
symbol (check mark icon) if the OneTouch does NOT successfully
connect to the test target or establish communication, based on
the parameters of the test. The check mark will be Red rather
than Green to indicate that the Pass on Test Failure feature is
enabled. Turn this setting On if you want to ensure that the
target is NOT accessible at your location.

Test failed - Connection available or communication
established.

Test passed - No connection available or unable to
access.
