Peter, CPU span on sup2t is unfortunately not implemented. It sounds like there are both software and hardware limitations to making it happen so it may never show up. There's an internal but I'll work on pushing external (meaning currently it's pretty useless but give it 24-48 hours), CSCsz68416.
You can use flexible netflow on the control-plane interface, but that won't be very helpful here. You could rely on netdr to capture packets and tie it to an EEM script to stop a circular capture when the problem happens. https://supportforums.cisco.com/document/59956/troubleshooting-netdr-capture-sup7206500 On Tue, Apr 22, 2014 at 4:04 AM, Peter Rathlev <pe...@rathlev.dk> wrote: > Would anyone know how to SPAN the CPU of a Sup2T running IOS 15?
