Hi Everyone,
I've been fighting an issue with a 2821 router for some time now. I'm trying to pull the top talkers from an interface, however the cache is empty. I verified the configuration with a known working 2821 and the output for the interfaces are the same. Any help would be greatly appreciated!

sh ip flow export
sh ip flow top-talker
