# VMware NSX OpenStack Neutron REST API Extensions



## General Information
This document describes the REST API extensions integrated with the
VMware [NSX OpenStack neutron plugins](https://wiki.openstack.org/wiki/Neutron/VMware_NSX_plugins).
The intent of this document is to supplement the
[OpenStack neutron REST API guide](https://docs.openstack.org/api-ref/network/v2) by describing
the extensions implemented by the VMware NSX neutron plugins.

The VMware NSX neutron plugins implement
[Neutron API extensions](https://wiki.openstack.org/wiki/NeutronDevelopment#API_Extensions)
by defining new top-level REST resources, operations (e.g. verbs) and attribute extensions
to existing neutron REST API entities (depending on the extension). As all extensions apply
to the neutron REST API, the
[general information](https://docs.openstack.org/api-ref/network/v2/#general-information)
for the neutron API applies here as well.

The VMware NSX neutron extensions supported by your plugin will depend on the version
of VMware NSX used. Two versions described herein are:
  * [NSX for vSphere](https://www.vmware.com/support/pubs/nsx_pubs.html) aka 'NSX-V'.
  * [NSX-T](https://docs.vmware.com/en/VMware-NSX-T/index.html).

### [Advanced Service Providers](#advanced-service-providers)

attribute to neutron [subnets](https://docs.openstack.org/api-ref/network/v2/#subnets).
This read-only attribute is a list of NSX advanced service provider IDs associated on a per-subnet
basis. The advanced service provider IDs are populated by the plugin automatically
when interfacing with the NSX manager backend.

###### Extension Type
Resource attribute extension.

###### Supported NSX Versions
NSX-V.

###### Supported Verbs
None (read-only).

###### Extended Resource
[subnet](https://docs.openstack.org/api-ref/network/v2/#subnets)

###### Extension Attribute(s)
  * `advanced_service_providers`: A list of NSX advanced service provider IDs (in `string` format)
    associated with the subnet.

### [Provider Networks](#provider-networks)

###### Description
The VMware NSX neutron plugins also support the
[neutron provider networks extension](https://docs.openstack.org/neutron/latest/admin/archives/adv-features.html#provider-networks).
Provider network extensions add [attributes](https://docs.openstack.org/neutron/latest/admin/archives/adv-features.html#provider-attributes)
to neutron [networks](https://docs.openstack.org/api-ref/network/v2/#networks)
enabling providers to map virtual networks onto physical networks, or in this case
onto physical networks in NSX.

###### Extension Type
Resource attribute extensions.

###### Supported NSX Versions
NSX-T, NSX-V.

###### Supported Verbs
See the
[neutron provider networks extension](https://docs.openstack.org/api-ref/network/v2/#networks-provider-extended-attributes-networks)
API reference documentation.

###### Extended Resource
  * [networks](https://docs.openstack.org/api-ref/network/v2/#networks)

###### Extension Attribute(s)
  * `provider:network_type`: For the NSX plugins valid values are `flat` or `vlan`.
  * `provider:physical_network`: For the NSX plugins, this value should be the UUID
     of the NSX transport zone to bridge the network on.
  * `provider:segmentation_id`: For the NSX plugins, this value should be set to the
     VLAN identifier of the physical network, or unset of the network type is `flat`.

###### Example Response
```json
{
    "network": {
        "status": "ACTIVE",
        "subnets": [
            "54d6f61d-db07-451c-9ab3-b9609b6b6f0b"
        ],

    }
}
```



### [Provider Security Groups](#provider-security-groups)

###### Description
This extension enables support for provider-only created/managed neutron
[security groups](https://docs.openstack.org/api-ref/network/v2/#security-groups-security-groups).
To enable this support a `provider` boolean attribute is added to neutron security
groups indicating if the group is a provider-only group. Additionally, neutron
[ports](https://docs.openstack.org/api-ref/network/v2/#ports) are extended with
a `provider_security_groups` attribute that indicates a list of provider-only
security groups belonging to the said port.

###### Extension Type
Resource attribute extensions.

###### Supported NSX Versions
NSX-T, NSX-V.

###### Supported Verbs
The `provider` attribute on neutron security groups is only settable during creation (POST).
However the `provider_security_groups` attribute on ports supports both POST and PUT.

###### Extended Resource
  * [ports](https://docs.openstack.org/api-ref/network/v2/#ports)
  * [security groups](https://docs.openstack.org/api-ref/network/v2/#security-groups-security-groups)

###### Extension Attribute(s)
  * `provider`: A boolean indicating if the security group is provider-only.
  * `provider_security_groups`: A list of provider-only security group UUIDs associated
    with a said port.

###### Example Response
