Cisco Switch Matrix

[Shawn L <shawnl () up net>]

Has anyone seen a good matrix of Cisco switches and their port-types, etc?
I'm looking for something where I can say 'I need a switch with X 10-gig
ports and Y 1-gig sfp ports, which models meet that criteria?'

I know I can look through all of the data sheets at cisco's website, but
there has to be a better way to see the specs of a large array of switches
at a glance.

thanks
