I confirm the same behavior between the Dell 5012 and Extreme Networks
Alpine 3808 switch:
The GBIC / fiber port on the 5012 indicates a link; however, the Alpine
switch doesn't see anything.  However, it does work when I use one of the
copper ports from the 5012 to interconnect the switches.  Is the problem you
are experiencing associated with the GBIC ports (11 & 12)? Perhaps this is a
Dell problem?
