Dear All. I have no problem configuring network via Hosrizon-dasboard. I start playing with python for some task. I got succsess in creating network. I create a router, with one interface connected to existing 'ext-network' .. success. But I fail when I try to add a port to that router for connecting to existing internal network. Here is part of my python shell. -------------------- body_value = { 'port': { 'admin_state_up': True, 'device_owner': 'network:router_interface', 'device_id': 'a616dcc0-1f72-4424-9494-4d13b42445ee', 'name': 'Bino-net-01-02', 'network_id': 'dfc8ed54-106d-48d0-8b45-cbd3cf0fbb79', 'binding:host_id': 'rocky-controller.mynet.net', 'binding:profile': {}, 'binding:vnic_type': 'normal', 'fixed_ips': [{ 'subnet_id': 'c71a86a3-f9a8-4e60-828e-5d6f87e58ac9', 'ip_address': '192.168.202.254' }], }} response = nt.create_port(body=body_value) response {'port': {'allowed_address_pairs': [], 'extra_dhcp_opts': [], 'updated_at': '2018-12-07T08:10:24Z', 'device_owner': 'network:router_interface', 'revision_number': 1, 'port_security_enabled': False, 'binding:profile': {}, 'fixed_ips': [{'subnet_id': 'c71a86a3-f9a8-4e60-828e-5d6f87e58ac9', 'ip_address': '192.168.202.254'}], 'id': 'd02eb0f0-663f-423f-af4e-c969ccb9dc25', 'security_groups': [], 'binding:vif_details': {'port_filter': True, 'datapath_type': 'system', 'ovs_hybrid_plug': True}, 'binding:vif_type': 'ovs', 'mac_address': 'fa:16:3e:e2:9d:8f', 'project_id': 'c0b89f614b5a457cb5acef8fe8c2b320', 'status': 'DOWN', 'binding:host_id': 'rocky-controller.mynet.net', 'description': '', 'tags': [], 'device_id': 'a616dcc0-1f72-4424-9494-4d13b42445ee', 'name': 'Bino-net-01-02', 'admin_state_up': True, 'network_id': 'dfc8ed54-106d-48d0-8b45-cbd3cf0fbb79', 'tenant_id': 'c0b89f614b5a457cb5acef8fe8c2b320', 'created_at': '2018-12-07T08:10:24Z', 'binding:vnic_type': 'normal'}} -------------------- 'status' always 'DOWN'.
