Thanks Jason.  I remember when doing the R/S lab, I drew my own L2 and L3 maps. 
 Would you recommend just creating a L2 map at the very beginning and then 
writing on trunk links every time a new VLAN needs to be added?

Diagramming was key for me.  Without those, there was just too much information 
to ensure that I had ports correct.

Hi all -

I keep seeing the requirement, "allow only necessary vlans".  Does anyone have 
a good strategy for ensuring that only the necessary VLAN's are allowed on 
every port?  It's a task that sounds simple at first, but as VLAN's get added 
as the lab goes along, it would be easy to add one too many.  Thoughts on 
ensuring only the exact VLANs you need are allowed?

Thanks
