The dest_indx is the destination interface. The output is the hex and needs some translation steps to find it.

Here is a great link I found that may help understanding this a bit more, although it is pretty much a whitepaper by Cisco so it is pretty tech-speak and dry. This will walk you through every step to track down everything you need.
