This is a read-write flag that, per its description, determines whether a cieTestCompletion trap is issued when a test crypto session finishes, and the description notes it's the admin's own responsibility to ensure the SNMP trap-delivery configuration actually gets that trap somewhere. It matters for anyone running on-demand encryption diagnostics on this device, since without this set to true (and a working trap destination configured), the test's completion would go unnoticed except by manually polling status. An admin scripting an automated crypto-connectivity test would set this to true before kicking off the test so the NMS gets notified the moment it finishes.
