N2224PX-ON questions

I'm sure these are easy I'm just trying to work on another issue as well.

The port status lights on the N2224 say green auto full, yellow auto less than full.

My link to a cisco 2960 shows yellow but status shows a-1000/full on both sides.  So, which is it?

 

Also, I'm attempting to trouble shoot an issue where a cisco 2960 is trunked to a 3048 and the 2960 shows a link but the 3048 shows down. It was up when we first connected the 2960 but at some point it just stopped... no config change. we rebooted but now its just down.

In troubleshooting this I have a 2224 connected to a 2960 and I was attempting to get a speed mismatch. I changed the speed on the 2960 to 100 but I don't see a command to change the speed on the 2224.

speed didn't work

I see in the users guide there's auto negotiate but that command isn't available on my port configs. (console)

Thanks
