Even though you are asking this question with regard to what can
be done on the router itself, it's worth mentioning, if only for
the archives, a non-router approach to the problem...especially if
you are an enterprise network manager. It's even worth
mentioning despite the fact that I work for a company that provides
said approach.


Some of our enterprise customers place distributed Sniffers on their 
internet links themselves. Upon receiving an alert, they connect to the
Sniffer
and click on Top Ten talkers by bytes (presented in pie/bar chart).

You want to put a box like this to analyze and dozen OC-12c(s)? I know that
the sales people for boxes like this right now are really hurting for
business but give us a break.
