For SLES15 SP5, this is fixed in a maintenance release:


Changelog contains:  + vxlan: don't format unknown rtnl attrs (bsc#1219751)

For SLES15 SP4, a patch has been created by engineering which provides a resolution.

If there is a future maintenance release containing the SLES15 SP4 patch, this document will be updated to reflect that information.


This is due to a bug.

Additional Information

A support contract is required in order to request a copy of the SLES15 SP4  patch.
