negotiated trunks in inital config?
All, I wanted to know what is the philosophy about working practice labs, mock labs, and even the real lab when you run into negotiated (n-isl or n-dot1q) trunks as a initial configuration. Should we start out with shutting all trunk links down until told otherwise and admin those interfaces up when needed? If we see where a negotiated trunk link is already up should we leave it alone and just make note that we already have a trunk link between two or more switches? Knowing the 3550 defaults to dynamic desirable, and the 3560 defaults to dynamic auto what should be our approach when we first start out with inital configuration and we notice that we already have a negotiated trunk link already trunking for us. Please let me know...thanks!
