Setting this value to true before activating the ping with wwpLeosPingActivate causes the device to ping the target continuously until wwpLeosPingActivate is explicitly set back to false; it cannot be changed once a ping is already running, and it resets to false once the ping halts, defaulting to false. An admin uses this for an ongoing reachability monitor rather than a fixed-count test, useful when watching a link recover after a known outage. Setting wwpLeosPingUntilStopped to true and then wwpLeosPingActivate to true starts an indefinite ping that only stops when the admin manually deactivates it.
