N7710, 1G SFP on F3 module

[michael-luo]

I tried to use a 1G SFP on the N7710 F3 module.  But kept getting "Transceiver speed does not match the speed configured on the port" message.

Is there any tricks on that?  e.g. do I have to configure the port speed / plug in the SPF in specific order?  Thanks!

That's odd. According to this link 1Gbps is supported on the newest version of NX-OS:

Try defaulting the port, plug the SFP out and back in and then setting the port speed.
