Manage Networking service quotas
================================
A quota limits the number of available resources. A default
quota might be enforced for all projects. When you try to create
more resources than the quota allows, an error occurs:
.. code-block:: console
$ openstack network create test_net
Quota exceeded for resources: ['network']
Per-project quota configuration is also supported by the quota
extension API. See :ref:`cfg_quotas_per_tenant` for details.
Basic quota configuration
~~~~~~~~~~~~~~~~~~~~~~~~~
In the Networking default quota mechanism, all projects have
the same quota values, such as the number of resources that a
project can create.
The quota value is defined in the OpenStack Networking
``/etc/neutron/neutron.conf`` configuration file. This example shows the
default quota values:
.. code-block:: ini
[quotas]
# number of networks allowed per tenant, and minus means unlimited
quota_network = 100
# number of subnets allowed per tenant, and minus means unlimited
quota_subnet = 100
# number of ports allowed per tenant, and minus means unlimited
quota_port = 500
# default driver to use for quota checks
quota_driver = neutron.quota.ConfDriver
OpenStack Networking also supports quotas for L3 resources:
router and floating IP. Add these lines to the
``quotas`` section in the ``/etc/neutron/neutron.conf`` file:
.. code-block:: ini
[quotas]
# number of routers allowed per tenant, and minus means unlimited
quota_router = 10
# number of floating IPs allowed per tenant, and minus means unlimited
quota_floatingip = 50
OpenStack Networking also supports quotas for security group
resources: number of security groups and the number of rules for
each security group. Add these lines to the
``quotas`` section in the ``/etc/neutron/neutron.conf`` file:
.. code-block:: ini
[quotas]
# number of security groups per tenant, and minus means unlimited
quota_security_group = 10
# number of security rules allowed per tenant, and minus means unlimited
quota_security_group_rule = 100
.. _cfg_quotas_per_tenant:
Configure per-project quotas
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
OpenStack Networking also supports per-project quota limit by
quota extension API.
Use these commands to manage per-project quotas:
neutron quota-delete
Delete defined quotas for a specified project
openstack quota show
Lists defined quotas for all projects
openstack quota show PROJECT_ID
Shows quotas for a specified project
neutron quota-default-show
Show default quotas for a specified project
openstack quota set
Updates quotas for a specified project
Only users with the ``admin`` role can change a quota value. By default,
the default set of quotas are enforced for all projects, so no
:command:`quota-create` command exists.
#. Configure Networking to show per-project quotas
Set the ``quota_driver`` option in the ``/etc/neutron/neutron.conf`` file.
.. code-block:: ini
quota_driver = neutron.db.quota_db.DbQuotaDriver
When you set this option, the output for Networking commands shows ``quotas``.
#. List Networking extensions.
To list the Networking extensions, run this command:
.. code-block:: console
$ openstack extension list --network
The command shows the ``quotas`` extension, which provides
per-project quota management support.
.. note::
Many of the extensions shown below are supported in the Mitaka release and later.
.. code-block:: console

#. Show information for the quotas extension.
To show information for the ``quotas`` extension, run this command:
.. code-block:: console
$ openstack extension show quotas

.. note::
:command:`openstack extension show` is only supported currently by networking
v2.
.. note::
Only some plug-ins support per-project quotas.
Specifically, Open vSwitch, Linux Bridge, and VMware NSX
support them, but new versions of other plug-ins might
bring additional functionality. See the documentation for
each plug-in.
#. List project's default quotas.
The :command:`openstack quota show` command lists quotas for the current
project.

#. Show per-project quota values.
The :command:`openstack quota show` command reports the current
set of quota limits. Administrators can provide the project ID of a
specific project with the :command:`openstack quota show` command
to view quotas for the specific project. If per-project quota
limits are not enabled for the project, the command shows
the default set of quotas:
.. note::
Additional quotas added in the Mitaka release include ``security_group``,
``security_group_rule``, ``subnet``, and ``subnetpool``.

To update the limits for an L3 resource such as, router
or floating IP, you must define new values for the quotas
after the ``--`` directive.
This example updates the limit of the number of floating
IPs for the specified project.
.. code-block:: console
$ openstack quota set --floating-ips 20 e436339c7f9c476cb3120cf3b9667377

You can update the limits of multiple resources by
including L2 resources and L3 resource through one
command:

--floating-ips 3 --routers 3 e436339c7f9c476cb3120cf3b9667377

#. Delete per-project quota values.
To clear per-project quota limits, use the
:command:`neutron quota-delete` command.
.. code-block:: console
$ neutron quota-delete --tenant_id e436339c7f9c476cb3120cf3b9667377
Deleted quota: e436339c7f9c476cb3120cf3b9667377
After you run this command, you can see that quota
values for the project are reset to the default values.

.. note::
Listing defualt quotas with the OpenStack command line client will
provide all quotas for networking and other services. Previously,
the :command:`neutron quota-show --tenant_id` would list only networking
quotas.
