Thanks for the comments.
I have already checked by redirection tools my all 301s are working quite fine.
Secondly, my lot of same nature pages of same subdomain have already been crawled quite fine with proper title, descriptions though i haven't done any change in my robots.txt after 301 redirects.
I have just seen my Bing webmaster which is showing me a lot of 301 redirects with those redirected urls under crawl information.
