[c-nsp] Catalyst reloads (was Re: Is Cisco equpiment de facto for you?

[Pete Lumbis]

You could connect a console and just leave it logging until the next
reload. I haven't seen it on switches, but I've see other boxes crash
without writing a crashinfo file. If it crashes or reloads for any
software related reason it will probably show something in the
console.
