full-duplex 10G SR

Hello!

i use 10G SFP but i i get message on my Cisco swith is

%CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on freenas ix0 (half duplex)




network card is Intel X520 DP
mothercard is C2550D4I
1 x PCI-E x8 slot


on NAS i use intel SFP from switch cisco i use cisco SFP and the link is fiber mm

Seems likely something's wrong, possibly with the card, possibly with the SFP+. What's the exact model number of the SFP+?

i changed the SFP but is the same , my SFP is

Intel 850nm MMF Fiber Module FTLX8571D3BCV-IT 10G SFP

Well that's definitely the right part for the X520. I'm trying to remember because I think I've seen this sort of thing before, but I just can't place what the cause was. If you loop the X520 back, does it show a link?

i change the card and SFP and same problem , i have link and every thing is ok but half duplex , do u know if my mother card can process 10G ?
is

Something's still not right because 10G doesn't really offer half duplex (though it's technically "possible"). Again, try looping the X520 back. Take a patch cable and remove the LC clips. Make a connection so that the transmit is connected to the receive, and see if the interface comes up and shows link. It should, though honestly I haven't tried it on an X520.

what is the output of the following 2 commands. replace 1/0/1 with whatever your ten gig interface is:

Code:

show run int te 1/0/1
show int te 1/0/1
