Narrative:
During initial climb after handoff to departure control we were cleared to FL340. Climbing through 3500 ft, TCASII showed TCASII advisory 500 ft above us, followed by TCASII resolution, 'reduce climb.' we leveled off, traffic passed overhead (indicated by TCASII) with no visual contact. TCASII stated 'clear of conflict.' we then checked with departure about traffic, he stated traffic was behind us at 4000 ft (no other comments). We then resumed our climb to FL340. Note: at level off TCASII showed traffic passed directly over us at 400 ft.
