Vyos cannot apply VLAN sub interface to bridge
Closed, ResolvedPublicBUG


Execute the following command:

set interfaces ethernet eth1 vif 3
set interfaces bridge br1 member interface eth1.3

The following error was reported:

No type  found for interface name: eth1

And in the actual running environment, DHCPv6 also reports errors, but due to configuration migration errors during upgrade, it cannot enter the normal routing working state, and there may be many errors, so I only repeat such errors in the virtual machine, please completely repeat whether it can run normally in such situation!

Event Timeline

See T2427, the fix for that was merged today and will be in the next ISO build. I'll test that new ISO too to see if I catch any migration errors (I tested it just on a test VM without upgrading and I didn't see any VLAN errors, several configured VLANs seemed to work)
Edit: I see the error is for eth vif in a bridge, I didn't test that, just vif on ethernet and eth in a bridge. I'll test it today.

Tested it right now, set interfaces bridge br0 member interface eth3.4 worked fine with latest current vyos-1x, so the next ISO should definitely have this fixed.
