Exactly!!! the task is to make the trunk port f0/14 a designated port. The problem is that f0/14 is a root port. There are 2 other ports connected to the root f0/13 and f0/15. If I change the cost all I’m doing is possibly making another port the root port and putting f0/14 into altn blocking state. Even if I make f0/13 or f0/15 the root port(I would have to make them trunks which was not asked for anywhere in the lab). I can’t make f0/14 a designated port, because that makes a loop and STP won’t allow that. The SG is wrong wrong wrong, and I was trying to find out if there is some “exotic” way to accomplish the task. —– Original Message —– From: “LJ” To: “John” Cc: Sent: Wednesday, July 09, 2008 10:46 AM Subject: Re: Can you make a root port a designated port?
