Thanks Shiran for sharing this, I will lab it up again. But this problem has
repeated 3rd time and not sure how to solve this.

Its on remote lab so i can not capture, i was thinking may be if some one
might have encountered this kind of problem, then he/she might have some
pointers for me to troubleshoot :-)
