Configure settings for the External test

For the tester to run external tests, configure the available settings.

CAUTION:

This test allows administrators who have permissions to edit the properties of Secure SD-WAN Engines to run arbitrary commands in the Secure SD-WAN Engine operating system.

Steps

In the Retry Count field, enter the number of times the tester tries to execute the test
We recommend always setting the retry count to more than 1 to avoid creating overly sensitive tests that burden the system unnecessarily.
In the Test Timeout field, enter the timeout in milliseconds.
- If the test being run does not return a response in the specified time, the test is considered to have failed.
- We recommend a timeout of 500–1000 milliseconds, depending on the external test script.
In the Command Line field, enter the command or script path.
Example:
```
/data/home/root/connectivity.sh
```
Tip: You can use custom properties profiles to upload the script to the Secure SD-WAN Engine.
Click OK.

Note: The command or script must return an exit code of 0 (zero) if it succeeds. Any non-zero return value is a failure.
Click Save and Refresh.

External Test Properties dialog box

Use this dialog box to run a custom script that has been uploaded to the Secure SD-WAN Engine.

Option	Definition
Name	The name of the test. If you want to run more than one instance of the same test type with different parameters, give each test a unique name.
Node (Clusters only)	Select whether to run the test on ALL nodes or only on a specific node.
States to Test	Select one or more Secure SD-WAN Engine states in which to run the test. Online — When selected, the test is run when the Secure SD-WAN Engine node is online. Offline — When selected, the test is run when the Secure SD-WAN Engine node is offline. Standby — (Clusters only) When selected, the test is run when the Secure SD-WAN Engine node is in the Standby state.
Test Interval	Specify how frequently the test is run. The minimum interval is one second and the maximum is 86400 (one day). We recommend a minimum interval of four seconds. Running a test too frequently can increase overhead.
Retry Count	Enter the number of times the tester tries to execute the test. We recommend always setting the retry count to more than 1 to avoid creating overly sensitive tests that burden the system unnecessarily.
Test Timeout	Enter the timeout in milliseconds. If the test being run does not return a response in the specified time, the test has failed. Avoid overly short timeout values. We recommend a timeout of 500–1000 ms, depending on the test.
Command Line	Enter the command or script path. The result must return an exit code of 0 (zero) if it succeeds. Any non-zero return value is a failure. CAUTION: This test allows administrators who have permissions to edit the properties of Secure SD-WAN Engines to run arbitrary commands in the Secure SD-WAN Engine operating system.
Failure section
Action	Select the action taken if a test fails. None — No action is taken. Offline — (Clusters only) The Secure SD-WAN Engine node goes offline, unless it is the last active node in a cluster or the node is in the Locked Online state. Force Offline — The Secure SD-WAN Engine node goes offline, even if it is the last node active node in a cluster or the node is in the Locked Online state. Use in cases in which a complete cut in traffic is a better option than a partially working Secure SD-WAN Engine. Force Speed (Inline Pair Link Speed test only) — If the test finds that the pair of inline ports has different speed/duplex settings, the speed/duplex on the higher speed/full duplex link is set to match the lower speed/half duplex setting on the other port. Correct and reliable operation requires identical settings.
Send Alert	When selected, sends an alert to notify administrators that a test has failed.
Send SNMP Trap	When selected, sends an SNMP Trap.
