Brian, 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?
