XGS SFP ports not working until you specify interface speed (1G or 10G XGS, v20)

Hi LHerzog ,

Thank you for reaching out to the community, yes you are right it has been a known issue since SFOS 19.0.0 GA-Build317.
You can find the details here - https://docs.sophos.com/support/kil/index.html

Thanks for your quick confirmation Vivek Jagad! So this is nothing to worry about. I'm testing the new hardware before migration and now just know I need to set interface speed manually.

I just needed to find out that this applies also for the onboard F1-F4 SFP Ports which are 1Gbit only. Using Sophos SFP FC module for 1:1 HA Link.
