Where do you find the non-consolidated vol. of S&P 500?

In neither 1 of the above, it doesn't show the actual vol., just the gross vol. of S&P 500

I can get the actual vol. of Nasdaq or NYSE

http://data.cnbc.com/quotes/COMP/tab/2

615,965,800

http://data.cnbc.com/quotes/.DJIA

832,023,000

But the link to S&P 500 seems to be the consolidated vol., not the actual vol.

Any1 knows where to get the info?
