outage-detection active-probe

Defines the number of consecutive active-probe failures that should be interpreted by the CNA decision-maker process as an outage for the prefix.

outage-detection active-probe { enable | disable |
 
       failure-threshold <fail-num> | measurement-threshold <meas-num> }
 
no outage-detection active-probe { enable | disable |
 
       failure-threshold | measurement-threshold }
 

• fail-num--number of consecutive failures that constitute an outage; range: 1 through 20; default 5
• meas-num--number of successes that constitute the end of an outage; range: 1 through 255; default 5

Must be in engine or decision policy configuration mode (config-engine or config-engine-policy), which requires privileged-level access.

Use once globally, and once per decision policy.

Use the outage-detection active-probe command to define an outage as measured by active probing.

If an active probe fails fail-num consecutive times over the same link, an outage will be declared for the targeted prefix over that link. (Failure means no response from the target for a length of time specified as the timeout value in the active probe configuration.)

The current value of num is displayed as probe-failure-threshold in the output generated by the show statistics command with dmaker as the argument.

The outage will be considered to have ended after meas-num active probe successes for that prefix over the same link.

Use the no form of the command to revert to the defaults, either globally or within a decision policy.
