 Description   

As you can see on the report below floating ip and snat tests fails.
On this report there are 2 networks one with vlan and the other with vxlan.
L2 and L3 tests pass but external network tests failed.

We can see that there are missing rules in t28 and t81.

when creating Flat after VLAN - the flat interface is missing in interfaces-state (operational)

It seems the first patch didn't work, there are still issues seen.
https://jenkins.opendaylight.org/sandbox/job/netvirt-csit-1node-openstack-newton-nodl-v2-upstream-transparent-revital3-carbon/2/

Need to upload logs here since sandbox will be deleted on Saturday.

Comment by Alon Kochba [ 22/Mar/17 ]

This bug is due to the fact that flat networks use "Transparent" port type, and VLAN networks use "Trunk Member".

However, when a Trunk Member port is configured, a Trunk port is also configured without any port binding - but with higher priority than the transparent rule.

It seems Flat should use Trunk instead of Transparent.
Also there seems to be an additional bug where even when all VLAN members are deleted, the trunk port remains.

Afaik, this was fixed with a work around of allowing interface-manager to create both interface-types on the same parent.

Is this still open to track the actual issue?
That is trunk-member deletion?

If there is a separate TR for that, can we close this?

The issue has not been solved yet but moving this to netvirt as the fix would not be in genius
