Re: High CPU load on 7609

system that much.

Totally agreed Joseph.
I'd expect at least it captured somewhere in the 'show proc cpu' command so
that u can see what is causing it. once it's PBR'd (L3) , all packets are
gonna punt onto the CPU.
May be it's documented somewhere and we don't know that secret location on
CCO yet :)

Do u mean u turned it into L2 switch? If so what a waste of 760X! :(
