SFP to SFP+ Uplink

[gerickson77]

We have two switches which need an uplink.  WS-C2960S-24TS-L V02 which supports SFP and Nexus 3548P-10G which supports SFP+

We've attempted to uplink/interconnect using 10GBASE-CU SFP+ to SFP+ passive twinax cable neither switches indicator light is showing connectivity.

Is this a cable issue, a config issue or a incompatibility between switches or protocol or negotiation abilities from SFP to SFP+?

Thank you very much for your thoughts.

The uplink ports on the 2960s is Gig only. If the 3548 uplinks ports are 10Gig than this will not work as you have mismatch speed between the 2 switches. If the 3548 support both SFP and SFP+ than you could try both side with SFP (1Gig) and test.

Hello I agree with Reza. You'd better to use same transceiver both side ( Check compatibility matrix first) Reza, Could you tel me how can I send you a private message please?
