The new sphinx version introduces some changes that break build: * Warns if code cannot be parsed for highlighting. Fix the code so that it can be parsed, this includes uncommenting "..." lines. * :option: works only with declared options, replace useage with simple ``. This change only handles a few files, more to come later. Change-Id: I957b102a0b3fb84f494e7f50ec35fa1c26a98bb5

Create and manage networks
Before you run commands, set environment variables using the OpenStack RC file.

The subnet-create
command has the following positional
and optional parameters:
The name or ID of the network to which the subnet belongs.
In this example,
net1
is a positional argument that specifies the network name.The CIDR of the subnet.
In this example,
192.168.2.0/24
is a positional argument that specifies the CIDR.The subnet name, which is optional.
In this example,
--name subnet1
specifies the name of the subnet.
For information and examples on more advanced use of neutron's
subnet
subcommand, see the OpenStack
Administrator Guide.
Create routers
Create a router:
$ openstack router create router1 +-------------------------+--------------------------------------+ | Field | Value | +-------------------------+--------------------------------------+ | admin_state_up | UP | | availability_zone_hints | | | availability_zones | | | created_at | 2016-12-22T18:48:57Z | | description | | | distributed | True | | external_gateway_info | null | | flavor_id | None | | ha | False | | headers | | | id | e25a24ee-3458-45c7-b16e-edf49092aab7 | | name | router1 | | project_id | e17431afc0524e0690484889a04b7fa0 | | revision_number | 1 | | routes | | | status | ACTIVE | | updated_at | 2016-12-22T18:48:57Z | +-------------------------+--------------------------------------+
Take note of the unique router identifier returned, this will be required in subsequent steps.
Link the router to the external provider network:
$ openstack router set ROUTER --external-gateway NETWORK
Replace ROUTER with the unique identifier of the router, replace NETWORK with the unique identifier of the external provider network.
Link the router to the subnet:
$ openstack router add subnet ROUTER SUBNET
Replace ROUTER with the unique identifier of the router, replace SUBNET with the unique identifier of the subnet.
Create ports
Create a port with specified IP address:
$ openstack port create --network net1 --fixed-ip subnet=subnet1,ip-address=192.168.2.40 port1 +-----------------------+-----------------------------------------+ | Field | Value | +-----------------------+-----------------------------------------+ | admin_state_up | UP | | allowed_address_pairs | | | binding_host_id | | | binding_profile | | | binding_vif_details | | | binding_vif_type | unbound | | binding_vnic_type | normal | | created_at | 2016-12-22T18:54:43Z | | description | | | device_id | | | device_owner | | | extra_dhcp_opts | | | fixed_ips | ip_address='192.168.2.40', subnet_id='a | | | 394689c-f547-4834-9778-3e0bb22130dc' | | headers | | | id | 031ddba8-3e3f-4c3c-ae26-7776905eb24f | | mac_address | fa:16:3e:df:3d:c7 | | name | port1 | | network_id | 9db55b7f-e803-4e1b-9bba-6262f60b96cb | | port_security_enabled | True | | project_id | e17431afc0524e0690484889a04b7fa0 | | revision_number | 5 | | security_groups | 84abb9eb-dc59-40c1-802c-4e173c345b6a | | status | DOWN | | updated_at | 2016-12-22T18:54:44Z | +-----------------------+-----------------------------------------+
In the previous command,
net1
is the network name, which is a positional argument.--fixed-ip subnet<subnet>,ip-address=192.168.2.40
is an option which specifies the port's fixed IP address we wanted.Note
When creating a port, you can specify any unallocated IP in the subnet even if the address is not in a pre-defined pool of allocated IP addresses (set by your cloud provider).
Create a port without specified IP address:
$ openstack port create port2 --network net1 +-----------------------+-----------------------------------------+ | Field | Value | +-----------------------+-----------------------------------------+ | admin_state_up | UP | | allowed_address_pairs | | | binding_host_id | | | binding_profile | | | binding_vif_details | | | binding_vif_type | unbound | | binding_vnic_type | normal | | created_at | 2016-12-22T18:56:06Z | | description | | | device_id | | | device_owner | | | extra_dhcp_opts | | | fixed_ips | ip_address='192.168.2.10', subnet_id='a | | | 394689c-f547-4834-9778-3e0bb22130dc' | | headers | | | id | eac47fcd-07ac-42dd-9993-5b36ac1f201b | | mac_address | fa:16:3e:96:ae:6e | | name | port2 | | network_id | 9db55b7f-e803-4e1b-9bba-6262f60b96cb | | port_security_enabled | True | | project_id | e17431afc0524e0690484889a04b7fa0 | | revision_number | 5 | | security_groups | 84abb9eb-dc59-40c1-802c-4e173c345b6a | | status | DOWN | | updated_at | 2016-12-22T18:56:06Z | +-----------------------+-----------------------------------------+
Note
Note that the system allocates one IP address if you do not specify an IP address in the
openstack port create
command.Note
You can specify a MAC address with
--mac-address MAC_ADDRESS
. If you specify an invalid MAC address, including00:00:00:00:00:00
orff:ff:ff:ff:ff:ff
, you will get an error.Query ports with specified fixed IP addresses:
$ neutron port-list --fixed-ips ip_address=192.168.2.2 \ ip_address=192.168.2.40 +----------------+------+-------------------+-------------------------------------------------+ | id | name | mac_address | fixed_ips | +----------------+------+-------------------+-------------------------------------------------+ | baf13412-26... | | fa:16:3e:f6:ec:c7 | {"subnet_id"... ..."ip_address": "192.168.2.2"} | | f7a08fe4-e7... | | fa:16:3e:97:e0:fc | {"subnet_id"... ..."ip_address": "192.168.2.40"}| +----------------+------+-------------------+-------------------------------------------------+
