Hi Vivek Jagad ,

Just found out as this is a passive copper cable there is no "program code" running on the transceiver. Is the Appliance maybe actively blocking transceivers from unknown vendors? Would this be visible in the logs?

Thanks,

M

I am not sure on that but I can share you the third-party transceivers/SFPs compatibility list, here is the KBA - https://support.sophos.com/support/s/article/KB-000037169?language=en_US
