I think I'll change the column name to "vtep_logical_switches" and so maybe readers could refer to the vtep schema manual. For the second point, the 'user' should be the CMS~ how about this: """ <column name="vtep_logical_switches"> Maps from the name of a vtep logical switch on the gateway to a logical port name. The logical port name must be unique; one way to do this is by concatenating the chassis name and the logical switch name. To include one vtep logical switch to an OVN logical network, a same named logical port should be created in the Logical_Port table and be attached to some Logical_Switch in the OVN_Northbound database. </column> """ _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
