Narrative:

Flying the ward 4 arrival into ewr, immediate TCASII resolution, traffic 300 ft below, closing at 2 O'clock 3 1/2 mi. We were at 11000 MSL, had no visual and ATC reported traffic with no altitude readout. Immediately followed TCASII command to climb at 2000 FPM, climbed to 11600 notifying ATC -- ZDC replied you 'can't climb.' at 11600 ft and level we saw the traffic at 1/2 mi 3 O'clock. Descended back to 11000 ft MSL and continued the STAR.
