Hi Daniel, which firmware branch did you upgrade wthin? guessing 12.1, but i'm planning an upgrade with a customer next week, so if you could share that information, so i know if there is something to be aware of.

I have upgraded to SDX version 12.1-58.15 and after that the XS IP is no longer reachable, but the SDX is still running successfully. I think they use the Link Local Address internally for communication between SVM and XS. For me it would only be interesting to know if this XS IP is no longer needed.

Thanks, will keep an eye out when i upgrade next week.

Link local connectivity is indeed used for SVM to XS communication internally so that shouldn't be an issue.

Indeed I have the same issue for 3 SDX when upgrading to latest 13 build, I opened a case with Citrix. It has to be a bug. No issue and I was wondering if it was a feature as my SVM and XenServer are on the same subnet.
