Good morning,
I have a 3750X switch, and I have two computers connected to it. I just setup link aggregation for the two PCs. They both show 2.0 Gbps for their link status, but when I copy a file from one PC to the other the speed is only 100MBps. Isn't it supposed to be 200MBps.
Here is some info that might help.
