Model: TL-SX3008F  
Hardware Version: V1
Firmware Version: 1.2

I'm trying to get a TL-SG2210MP (does not support 10gb) uplinked to a SX3008F using a SFP+ DAC. My research tells me this should be possible, however when connecting the two switches with the DAC cable there is no link.

 

I've tried manually setting the ports at 1000 but the results do not change.

 

The same cable work for uplinking to other devices, however all other devices support SFP+.

 

I'm looking for any suggestions on what to try next or for somone more qualified to tell me it's no possbile.

I think there is a difference between the SFP + DAC cables, some only support 10GB others have 1GB and 10GB, I use a unifi SFP+ DAC it supports both, I use it between an ER8411 10GB interface and an SG2428P which only has 1GB SFP

  @warllo It's either the cable or config. I have sg2210mp lagged to a sg3824x so going from SFP to SFP+ can work with DAC. Tripple check that the speed/duplex match (1000FD) on both ports. If that's correct it most likely your DAC. This is the ASIN (B09CDP6PG4) at Amazon for the cables I'm using.

@D-C 

 

Thanks for the response.

 

I've quadruple check the speed and duplex settings. I'm guessing its the DAC cable.

 

I'll try the one suggested.
