[j-nsp] 1000BaseT SFP

[Jerry Jones]

I think you need to specifically use the tri-state SFPs for this to work

SFP-1GE-FE-E-T	SFP capable of support 10/100/1000 speeds

Swapped cables etc, my question is can these 1000BaseT SFP's work at 100M? I can configure them as such
but do they actually work at 100M?

Thanks,
Keith
