I'm having problems connecting 1Gbps interfaces (just a simple autonegotiating 1 Gbps Laptop) direct to a Nexus 5020 port. I'm using a GLC-T in one of the ports that supports 1 Gbps (ports 1-16), and I've configured the speed to 1000.
The link tries to come up for a fraction of a second (by looking at the laptop port)then drops.
I've tried several ports and a couple of different GLC-T SFPs, and I'm using the latest software (n5000-uk22.214.171.124.N1.1.bin). I've even tried fixing negotiation, using a crossover cable, but no luck. Does anyone have any suggestions or know if this is a known problem?
