Hi All,
Have a Nexus 5548 (running 6.0.2.N1 OS) connected to a FEX 2248PQ via a QSFP+ to 4SFP+ breakout cable. All is linked up and operating fine. The 4 QSFP+ ports on the FEX switch don't seem to have an interface# associated to them. Therefore, I can't seem to view the digital diagnostics on the QSFP+ optics. I can view the diagnostics on all the other optics as those ports have interface#'s.
Anyone out there know how to view the diagnostics for the QSFP+ ports on the FEX switch?
Thanx.

found the answer. QSFP+ modules don't support DOM feature.

Right. Among the 40 Gbps transceivers only the CFP types support DOM, i.e., none of the QSFPs.
This matrix shows all the DOM-capable transceivers.
