I am pretty familiar with FEC, but don't know much about GEC. Is it just like FEC but using 1GB ports on a switch? Here's why I ask. I have a stack of 3 3548 switches that I have interconnected using the GBIC ports. I want to introduce a 3550-12T switch to this stack and I want to increase the bandwidth between the new switch and the rest of the stack. Can I combine two GBICs in a team between the 3550-12T and one of the stack members? Is this what is meant by GEC?
