ICMP/Ping

The ICMP Ping function checks the availability of a remote host by

sending ICMP Echo commands and waiting for the response from the

host.

NOTE: Although local hosts should normally respond to ping requests

within milliseconds, an ICMP timeout failure doesn't necessarily mean

that the remote host is actually functioning beyond its ability to echo

packets.

The ICMP/Ping function requires the following parameters:

• Make sure you…..ping the target computer – Select ‘Can’ to

specify that the check is successful if the server replies to the ping.

Select ‘Cannot’ to specify that the check fails if the server replies

to the ping.

• Number of Echo requests to send – Specify the number of pings to

be sent.

• Minimum number of expected replies – Specify the minimum

number of replies that must be received for the check to be

successful.

• Timeout (m.sec) for each reply – Specify the expected response

time (in milliseconds). This is the time that the check will wait for a

response to an echo request (i.e. the time between successive

echo requests).
