Description (partial)

Upon a policy deployment failure to a Firepower Threat Defense (FTD) device, any of the following symptoms might be encountered:
- Data interfaces flap (go down, then up), causing momentary traffic impact
- Active connections established through the device are removed and must re-establish

This situation is encountered if the Firepower Management Center deploys a policy to the Firepower Threat Defense device that contains any configuration modifications that are rejected by the Firepower Threat Defense.

This problem is not seen when the policy deployment contains no configuration modifications that are rejected.
