It is unclear how to reproduce the issue. So far, I always have multiple VLANs configured and accessible. The only time I see errors similar to the ones from the reporter, is when the same vlan with the same name is configured multiple times in a row (which is an input/configuration error)
This bug will autoclose, unless better details are provided about the initial state of the machine / cards, current and prior VLAN configuration attempts. So far I cannot detect invalid behaviour, and the only errors that are produced are correct (i.e. when attempting to create a duplicate interface name) ** Changed in: ubuntu-z-systems Status: Triaged => Incomplete ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Changed in: iproute2 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to iproute2 in Ubuntu.
