For the tester to run Link Status tests, configure the available settings.

For more details about the product and how to configure features, click Help or press F1.

## Steps

1. From the Interface drop-down list, select the interface on which the test is run.
   Note: On Engines, only the first interface that belongs to an Aggregated Link is shown in the list of interfaces. However, the Link Status test checks the status of all interfaces in the Aggregated Link.
2. (Aggregated link in load-balancing mode only) Select the percentage of aggregated links that must be down for the test to be considered failed.
3. Click OK.
4. Click Save and Refresh.

## Link Status Test Properties dialog box

Use this dialog box to check whether a network port reports the link as up or down.

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 Security Engine states in which to run the test. Online — When selected, the test is run when the Security Engine node is online. Offline — When selected, the test is run when the Security Engine node is offline. Standby — (Clusters only) When selected, the test is run when the Security 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.
Interface | Select the interface on which the test is run. ALL — All physical, modem, ADSL, and wireless interfaces. ALL with CVI — (Clusters only) All interfaces that have a cluster virtual IP address (CVI) Specific interfaces
Aggregated Links in Load-Balancing Mode | From the Test Fails if More Than drop-down list, select the percentage of aggregated links that must be down for the test to be considered failed.
Failure section
Action | Select the action taken if a test fails. None — No action is taken. Offline — (Clusters only) The Security 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 Security 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 Security 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.
