Re: Nexus network Design - Switching LOOP

Hi carlos,

you are right I shoudn't play with STP in nexus. I agree to this , but
looking for a workaround to this (can't go for design cange and don't
have ports available on 5k to connect 3750 directly there).These are
the issues which are teasers but you really enjoy solving them .
Experts Request your support in solving the puzzle.
