Has anyone seen this problem ? Any time my 2940 switches are reloaded, the gigabit SFP will not come back up, unless I do a shut, and no shut on the other end (4503). I do not see this on my 3750 switches. It only occurs on 4503 or 4506 switches. Both ends say they are connected, but pass no traffic until I bounce the 4500 side. I have tried various modes of port operation (nonnegotiate, trunk, dyn des, dyn, auto). Nothing seems to fix the problem. 4500 switches are running 12.2(25) SG and 12.2(31) SG.
Re: 2940-TF problem using SFP port attached to 4503
That might be the case if it were happening on just one, but I have a bunch of them doing this. Besides, the problem does not occur when I use 2940-3750 or 2940-2940 SFP connections. It only occurs on 2940-4500 switch connections. Also, this problem is easy to duplicate. I have a case open with TAC, but so far they have not come back with anything.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
