Sorry to resurrect such an old thread, but this is the closest thing I've found to a problem I'm having:
I have a GLC-SX-MMD (Cisco branded) in one of the 10G SFP+ ports (te0/1), but the interface never comes up. Weirdly, the other end of the fibre (on an ASR9001) shows as up/up and if I do a 'shut' on te0/1 on the ME3600X, the interface goes down on the ASR and back up again when I do a 'no shut'.
Is there anything you have to 'do' to get normal 1G SFPs working in the 10G SFP+ ports? Any odd commands you have to issue?
Okay, in case anyone else stumbles across my post, I've fixed it. Turns out to be a known 'interoperability' issue between the ME3x00X series and the ASR9000.
Lifted directly from the interoperability guide:
10GE ports on CISCO ME3600X/3800X operating at 1Gig rate On CISCO ME3600X/3800X the TenGig Ethernet ports can operate at 1 Gig when 1 Gig SFPs are plugged in. In such scenarios additional interoperability commands are required.
Auto negotiation is disabled by default on Gigabit Ethernet Interfaces in CISCO ASR 9000. Auto negotiation is enabled by default on Gigabit Ethernet Interfaces in CISCO ME3600X/3800X and CISCO ASR 903.
To establish the link between CISCO ASR 9000 and CISCO ME3600X/3800X, enable auto negotiation on CISCO ASR 9000.
Question: Have the phone connected and can ring out-but no sound coming from the handset - analog home phone - phone makes connection and pick up at the other end is ok. Can you help?
