Configure settings for the Link Status engine test

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. Select the Interface on which the test is run:
    • ALL Physical Interfaces, Modem Interfaces (Single Firewalls only), ADSL Interfaces (Single Firewalls only), and Wireless Interfaces (Single Firewalls only).
    • (Clusters only) ALL with CVI.
    • A single Physical Interface, a Modem Interface (Single Firewalls only), an ADSL Interface (Single Firewalls only), or a Wireless Interface (Single Firewalls only).
    Note: On Firewalls, 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 to save the changes to the configuration and refresh the policy on the engine.

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 NGFW Engine states in which to run the test:
  • Online — Test is run when the node is online.
  • Offline — Test is run when the node is offline.
  • Standby (Clusters only) — Test is run when the node is in the Standby state.
Test Interval Specifies how often the test is run. The minimum interval is one second and the maximum is 86400 (one day).
Note: We recommend a minimum interval of four seconds. Running a test too frequently can increase overhead.
Interface Select the interface to be tested.
Aggregated Links in Load-Balancing Mode You can set the test to be considered as failed if a certain percentage of aggregated links is down.
Failure section
Action Select the action taken if a test fails:
  • None — The state is not changed.
  • Offline (Clusters only) — The test switches the node offline. However, the tester does not turn offline the last active node in a cluster or nodes in the Locked Online state.
  • Force Offline — The node is forced to an offline state, even if it is the last node online in a cluster or if it is in the Locked Online state. Use in cases in which a complete cut in traffic is a better option than a partially working NGFW 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 Select to send an alert to notify administrators that a test has failed.
Send SNMP Trap Sends an SNMP Trap.
