VMware NSX OpenStack Neutron REST API Extensions

General Information

This document describes the REST API extensions integrated with the VMware NSX OpenStack neutron plugins. The intent of this document is to supplement the OpenStack neutron REST API guide by describing the extensions implemented by the VMware NSX neutron plugins.

The VMware NSX neutron plugins implement Neutron 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 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:

API Reference

Advanced Service Providers

Description

This resource attribute extensions adds the advanced_service_providers attribute to neutron 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

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

Provider Networks

Description

The VMware NSX neutron plugins also support the neutron provider networks extension. Provider network extensions add attributes to neutron 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 API reference documentation.

Extended Resource
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.

    }
}

Provider Security Groups

Description

This extension enables support for provider-only created/managed neutron 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 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
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.
