Catalyst Flow Export wierdness.

Wed Jun 8 19:09:53 UTC 2005

I've been out of the hands-on config game for a while, so certain portions 
of my clue is rusting. I knew the MSFC and the SUP both had their own 
ideas about how things were supposed to go, but (especially with IOS 
running on switches) wasn't 100% on the configuration behaviour. I can 
look at the configs and see that v5 export is configured, but I don't see 
an instruction to the SUP to export v5, which is what's tripping up my 
collection. Netflow being something our engineers haven't worked with 
extensively, and required configurations on recent IOS on Cats being 
something I'm not up to speed on, there's a a divide between me saying 
it's broken, and them saying that it's configured and that my tools are 
broken.

So there's head scratching and finger pointing on both sides that just 
needed a nudge. The versions didn't make the difference, the clued 
respondants still saw the break for what it was.

Thanks again.
