Just for the rack question, if I could start over without spending tons on my own rack I would definitely go with dynamips, a couple WS-C3560-8PC-S's, and use your 2500's for your backbones. ...

Howard, Exactly same experience like me. Only on 3560, you can use class-default. For 3550 you must create classes to match all other traffic.

The reason I ask is because I've seen it written in a few places that using the 3550 class-default class to match the remaining layer 2 or 3 traffic is a hit and miss on whether or not it will work correctly. A few weeks ago I was marked down in a Mock lab for using the class to match all remaining traffic....but then it was shown as being used in the solution for the question? :o) Would you recommend using class-default or would you go for what seems to be the safest option of seperate classes for layer 3 and layer 2 matching their acl's (IP and mac matching any any or 0x0 0xFFFF) in my policy map?

To load-balance from source at SW1 to destinations at SW2, you will need to configure the etherchannel as: port-channel load-balance dest-mac Obviously, the return traffic would need the opposite (source-mac)....
