On a Palo Alto Networks firewall, LACP pre-negotiation means the interface actively sends LACP packets to negotiate the aggregate link instead of waiting for the peer.
LACP mode = Active → The device initiates LACP negotiations by sending LACP PDUs.
LACP mode = Passive → The device waits for the peer to initiate, so no pre-negotiation occurs.

Path quality profiles for SD-WAN are created and managed centrally in Panorama using the REST API, and the SDWanPathQualityProfiles object endpoint is specifically designed to programmatically define latency, jitter, and packet-loss thresholds for SD-WAN monitoring across multiple tenants and devices.
