What are the modules you use?

Can you rule out this is a problem with the module and cable compatibility issue? Firmware may change the parameters and making them go bad. Use the our modules and this should not be a problem.

I recommend you contact the support about this for further investigation.

Hello, I'm using CN-0358VV DELL DAC cable for uplink and 053HVN-HPC for connect to endpoint devices such as Broadcom Adv. Dual 10Gb Ethernet (shipped from DELL {PowerEdge R650xs}) So I don't know.

Have you contacted the support regarding this?

Note we don't guarantee any support/compatibility to third-party modules. We, so far, have not ruled out the possibility of the compatibility issue.

 

Hello, I'm not contacting the support yet. I bought two TL-SM5310-T (https://www.tp-link.com/us/business-networking/accessory/tl-sm5310-t/) modules today. The CAT7 cable arriving tomorrow. I give it a try. I understand the compatibility issues of modules, but this is a nonsense if tp-llink not supporting third party vendors especially DELL components. We have DELL Servers and DELL recommend use DELL hardware and accessories, that's why we using the DELL recommens DAC cables. And originally we bought two of SX3016F (one for spare) and the second switch produced that problem too! Anyway! Is there a GNS3 image of tp-link switches especially SX3016F for simulating any other issues?
