The packets for SW1/2 so far show DTP and PAgP. Now, PAgP is Cisco-proprietary Etherchannel, but DTP is for trunking negotiation between switches.

If you haven't looked at Cisco DevNet, it's a really hoppin' resource for hands on work.

(Who says 'hoppin' resource'?)

I'm working from two articles to:
