Configuring The Tcp Half Open Template - HPE FlexNetwork 5510 HI Series Network Management And Monitoring Configuration Manual

Step

Configuring the TCP half open template

IMPORTANT:
This feature is available in Release 1121 and later.
A feature that uses the TCP half open template performs the TCP half open operation to test whether
the TCP service is available on the server. The TCP half open operation is used when the feature
cannot get a response from the TCP server through an existing TCP connection.
In the TCP half open operation, the NQA client sends a TCP ACK packet to the server. If the client
receives an RST packet, it considers that the TCP service is available on the server.
To configure the TCP half open template:
Step
1. Enter system view.
2. Create a TCP half open
template and enter its view.
3. (Optional.)
destination IP address of the
operation.
4. (Optional.) Specify the source
IP address for the probe
packets.
5. (Optional.) Specify the next
hop IP address for the probe
packets.
6. (Optional.)
probe result sending on a
per-probe basis.

Remarks
N/A
By default, no TCP half open
templates exist.
By default, no destination
address is specified.
By default, the packets take the
primary IP address of the output
interface as their source IP
address.
The source IP address must be
the IP address of a local
interface, and the interface must
be up. Otherwise, no probe
packets can be sent out.
By default, the IP address of the
next hop is configured.
By default, the probe result is
sent to the feature that uses the
template after three consecutive
failed or successful probes.
If you execute the reaction
trigger per-probe
reaction trigger probe-pass
commands multiple times, the

If you execute the reaction
trigger per-probe

commands multiple times, the
