Narrative:
At 11000 ft TCASII commanded an RA to climb. Climbed to 300- 400 ft above 11000 ft to end the RA command. Advised ATC with actions. ATC acknowledged the traffic. Supplemental information from acn 206832: we were at 11000 ft. We were issued traffic to our right climbing out. We then received a TCASII RA and climbed about 400 ft. I then saw the traffic to our right about 3 mi away. We reported the TA to the controller and returned to our altitude.
