Hi,According to the


According to the Limitations section of the NX-OS 6.2 release notes, this is not supported:

N77-F348XP-23: 1 Gigabit Ethernet Not Supported
On the Cisco Nexus 7700 48-port 1/10-Gigabit Ethernet SFP+ I/O module (N77-F348XP-23), 1 Gigabit Ethernet port speed is not supported on the F3 Series modules in Cisco Nexus Release 6.2(6).

I don't think the wording is very clear, but the way I read this is that it's a software limitation that will change in later releases. Especially as it would be a pretty useless 1/10 GE module if it didn't support 1GE.
