QSFP+ ports, do they support regular SFPs ?

[gnijs]

Hi all,

I have a question regarding QSFP+ ports on Nexus 5672UP and 3000 series. Can you plug in a normal 10GE LR SFP in the QSFP+ ports ?

(so the port converts to a regular 10GE port, not 40GE) ?

I am looking in particular to connect a QSFP+ switch with 10GE long-range fiber (other ports are all RJ45, ie C3172TQ) ?

I know there is a 4x 10GE breakout cable, but this is SR, i need LR...

regards,

GN

Hi GN, 

there is actually a module that can be used within the QSFP ports to convert QSFP+ to SFP+ or GLC.

Have a look.

Hi,

I assume you also purchased 2 x SFP-10G-LR= right?

The breakout ports should be configured : See "

Switching Between QSFP and SFP+ Ports"

Interfaces_Configuration_Guide_602_U11_chapter_010.html

That should be it.

The Module should be supported on the Nexus 3172 hence, it should work.

Hope this helps.
