I have a Dell X4012 Switch. I have installed SFP+ and SFP transceivers into it. It is going to work as a fiber switch for all the campus and will put the traffic into our Sonicwall. The problem I am having is that on restart, my ports come up but immediately go back down. When I try setting negotiation to 10g on the SFP+ ports, it gives me the error "Critical Error: Port x/x/x is of speed 1g. It cannot be changed to speed 10g." I am assuming that this is why the port status are down, because the ports that are on the switch and firewall are SFP+ pushing 10G speed but the switch X4012 switch won't accept more than 1g which doesn't make sense because they are ALL 10g ports! I am beating my head over this. My theory is that I cannot have a combination of SFP and SFP+ transceivers otherwise it only allows throughput of the weakest link. I will test and update if that is the issue, otherwise, some help would be greatly appreciated.

EDIT:

Seriously, what in the flying flock am I missing here? The way this is setup is that we have single mode fiber coming in from 9 different locations. They are terminating into a fiber patch panel, then from there going into a different port on the X4012 switch for each location. There is one going from one port into our NSA sonicwall appliance. Some of the switches on the other end are only SFP switches pushing 1g throughput while some are 10gb throughput with SFP+. The problem I am having is that the X4012 switch ABSOLUTELY REFUSES to be put into 10gb speeds!!! I have confirmed that when I set the negotiation rate of one of the SFP+ switches to 1gb then it will work, and all the switches with SFPs will work. So the problem is that the X4012 will not allow me to set any of the ports to 10G speed giving me the Critical Error: Port x/x/x is of 1g. You cannot set it to 10G. I thought the freaking point of this switch according to dell is that this has twelve 10g ports but it won't let me set it to 10gb? An just so I clear it up, I have tried removing ALL SFP transceivers from switch only leaving the SFP+ transceivers and their associated 10g devices, the problem is that the only way to access the web managment is basically through 1g speed transceiver that came with switch, and the CLI has NO functionality at all. It is so basic, I have tried using the CLI to manually set all the interface's speeds but it has no option.

So Dell? What the fudge? What do I do here, what is the issue. I need to fix this!!!
