Configuring Probes; Creating A Probe And Selecting Its Type - HP 7102dl - ProCurve Secure Router Configuration Manual

Configuring Probes

To configure a probe, you must complete these tasks:
1. Create and name the probe and select its type.
2. Specify the probe's destination.
3. Configure the probe's tolerance.
4. Activate the probe.
You can use the following default settings or your own custom settings:
period—default: 60 seconds
timeout—default: 1.5 seconds for ICMP, 10 seconds for TCP or HTTP
source address—default: the outbound interface's address
source port (for TCP and HTTP)—default: the port automatically selected
by the probe
Other options vary, depending on the type of probe you have selected, and are
documented separately for each type.
Each probe sends packets to a single destination address. You must configure
a different probe for each monitored server or destination network.

Creating a Probe and Selecting Its Type

The probe type is one of your most important decisions. There are three
probe types:
ICMP echo—Use this probe type if you simply want to test connectivity
so that a track can remove faulty static routes. This is the most basic probe
type; the default packet size is relatively small, so the probe adds little
overhead. For an ICMP echo probe, which transmits ICMP echo packets,
a test passes if the destination returns a valid response before the timeout
expires.
TCP connect—Use this probe type if you want to test a remote server that
runs a TCP application and does not respond to ICMP echo probes. For
tests, the probe initiates a three-way TCP handshake. If the server sends
a valid response before the timeout expires, the probe considers the test
to have passed and terminates the TCP connection.
