Hi
is it possible to force 1G negotiation using x670 and 1/10G SFP+ ?

Hello Dawid

Yes the ports on 670 will auto select based on the optic that is installed so if you put in a 1G optic it will go to 1G speed.

You can set the speed to 1G as well

Thanks

Hey Dawid

Sorry I believe the answer is no that when a SFP+ optic is in it will be set to 10G. This is based on the concepts guide "SFP+ optics, must have their speed configured to 10G auto off"

Unfortunately I do not have the correct equipment to test.

Thanks
