All,
There's something peculiar about what I read in an article on Cisco's site, and I'm wanting to get clarification:
The bottom part in this article under Figure 10: Local Switching, indicates that Stackwise doesn't locally switch, but Stackwise+ does. It *sounds* like if I send traffic from port 3/2 to port 3/23, it's going to circle the ring before getting to the port. Am I reading this right? Stackwise+ is only available on the 3750-E switches, and I have 3750-G.
Thanks,
John

The article looks like it goes against everything a switch is supposed to do for port-to-port traffic....now you have traffic traversing the stack cable needlessly.....

Thanks for the congrats, still can't get used to seeing it each time i log in
Does seem to be a bit counterintuitive but i can't see any other way of reading it.

I just read the whole article and have come to the same conclusion as you ie. with Stackwise because it does not support local switching and because it uses soruce stripping even a packet destined for a port on the same switch has to go right round the stack ring. Odd but that's what it is saying. I'll do a bit more digging but i think you are right in this.
