Environment: Openstack Victoria, OpenContrail (TungstenFabric) R2011. Problem: Trunk ports doesn't have standard attributes such as description, timestamp. I have an environment where core plugin is OpenContrail. OpenContrail has tf-neutron-plugin for proper work with neutron. There is TrunkPlugin, that proxies all trunk-related request to the OpenContrail backend. Here is the link for this plugin. https://gerrit.tungsten.io/r/gitweb?p=tungstenfabric/tf-neutron-plugin.git;a=blob;f=neutron_plugin_contrail/plugins/opencontrail/services/trunk/plugin.py;h=35fc3310911143fd3b4cf8997c23d0358d652dba;hb=refs/heads/master According to the openstack documentation: Resources that inherit from the HasStandardAttributes DB class can automatically have the extensions written for standard attributes (e.g. timestamps, revision number, etc) extend their resources by defining the ‘api_collections’ on their model. These are used by extensions for standard attr resources to generate the extended resources map. As I understood, it works only for plugins, which using Openstack database. For example, openstack native trunk plugin has models.py file where we can see this inheritance. https://github.com/openstack/neutron/blob/master/neutron/services/trunk/models.py#L26 In case of OpenContrail+OpenStack Trunk plugin only redirect requests. What can I do to make Contrail Trunk plugin works in the same way? I'll appreciate any help. Thanks in advance. -------------- next part -------------- An HTML attachment was scrubbed...
