Hello Folks!
Thanks for taking your time :)
I have a problem with a C750 Core with 4 Stacks. Actually i see on 2 Fiber GBIT IF the Line Protocol going down and up regularily. Its only on the Core. NOT on the other sides switch. He doesnt seem to recognize it.
Any idea?

I see no errors on the Interfaces.
Thanks!
--edit--
also.. i had this on another port on the same switch -> we move it from 2/0/6 to 2/0/8 and now it works without a problem (also moving the GBIC!) i didnt have the error on 2/0/1 and 2/0/2 then. They began after moving 2/0/6 to 2/0/8

Hi. I also have this problem, where the fiber link, goes down for 3 sec, and the other switch doesnt notice it, like its happening inside ios or inside module.
Im using 3560 switches with this ios : :c3560-ipbase-mz.122-35.SE5/c3560-ipbase-mz.122-35.SE5.bin
Anybody know a workaround ???
