[f-nsp] SFP-T in XMR

[Jorik Jonker]

Hi Niels and Ronald,

Thanks for your replies. 

The board is a 100/1000-board (is that what we call HF?), while the SFP is 1G-only to my knowledge. The board in the RX is a 1G-only too, which may be a clue.

UDLD is not enabled on any of the devices involved and I have played around with 'gig-default' and its three options without any luck. Finally, the 'speed-duplex' setting seems not applicable/available on this type of board.

I am going to contact the vendor explaining this situation, perhaps they can assist. Since, of course, there is a customer installation involved I was hoping to solve things without sending optics back to the vendor :-)

Best regards,

With the caveat that I've not used copper SFPs myself, is the XMR an 
HF blade?  Or do you maybe have UDLD ("link-keepalive") enabled?  
Have you tried "gig-default auto-gig"?
