_create_user	ID of the user who created this resource	string	Readonly
_last_modified_time	Timestamp of last modification	EpochMsTimestamp	Readonly Sortable
_last_modified_user	ID of the user who last modified this resource	string	Readonly
_links	References related to this resource The server will populate this field when returing the resource. Ignored on PUT and POST.	array of ResourceLink	Readonly
_protection	Indicates protection status of this resource Protection status is one of the following: PROTECTED - the client who retrieved the entity is not allowed to modify it. NOT_PROTECTED - the client who retrieved the entity is allowed to modify it REQUIRE_OVERRIDE - the client who retrieved the entity is a super user and can modify it, but only when providing the request header X-Allow-Overwrite=true. UNKNOWN - the _protection field could not be determined for this entity.	string	Readonly
_revision	Generation of this resource config The _revision property describes the current revision of the resource. To prevent clients from overwriting each other's changes, PUT operations must include the current _revision of the resource, which clients should obtain by issuing a GET operation. If the _revision provided in a PUT request is missing or stale, the operation will be rejected.	int
_schema	Schema for this resource	string	Readonly
_self	Link to this resource	SelfResourceLink	Readonly
_system_owned	Indicates system owned resource	boolean	Readonly
address_bindings	Address bindings for the Segment Static address binding used for the Segment. This field is deprecated and will be removed in a future release. Please use address_bindings in SegmentPort to configure static bindings.	array of PortAddressBindingEntry	Deprecated Maximum items: 512
admin_state	Represents Desired state of the Segment Admin state represents desired state of segment. It does not reflect the state of other logical entities connected/attached to the segment.	string	Enum: UP, DOWN Default: "UP"
advanced_config	Advanced configuration for Segment Advanced configuration for Segment.	SegmentAdvancedConfig
bridge_profiles	Bridge Profile Configuration Multiple distinct L2 bridge profiles can be configured.	array of BridgeProfileConfig
children	subtree for this type within policy tree subtree for this type within policy tree containing nested elements.	array of ChildPolicyConfigResource (Abstract type: pass one of the following concrete types) ChildDhcpStaticBindingConfig ChildSegmentDiscoveryProfileBindingMap ChildSegmentMonitoringProfileBindingMap ChildSegmentPort ChildSegmentQoSProfileBindingMap ChildSegmentSecurityProfileBindingMap ChildStaticARPConfig
connectivity_path	Policy path to the connecting Tier-0 or Tier-1 Policy path to the connecting Tier-0 or Tier-1. Valid only for segments created under Infra. This field can only be used for overlay segments. VLAN backed segments cannot have connectivity path set.	string
description	Description of this resource	string	Maximum length: 1024 Sortable
dhcp_config_path	Policy path to DHCP configuration Policy path to DHCP server or relay configuration to use for all IPv4 & IPv6 subnets configured on this segment.	string

domain_name	DNS domain name	string
evpn_segment	Evpn Segment Flag. Flag to indicate if the Segment is a Child-Segment of type EVPN.	boolean	Readonly
evpn_tenant_config_path	Policy path to the EvpnTenantConfig Policy path to the EvpnTenantConfig resource. Supported only for Route-Server Evpn Mode. Supported only for Overlay Segments. This will be populated for both Parent and Child segments participating in Evpn Route-Server Mode.	string
extra_configs	Extra configs on Segment This property could be used for vendor specific configuration in key value string pairs, the setting in extra_configs will be automatically inheritted by segment ports in the Segment.	array of SegmentExtraConfig
federation_config	Federation releated config Additional config for federation.	FederationConnectivityConfig	Readonly
id	Unique identifier of this resource	string	Sortable
l2_extension	Configuration for extending Segment through L2 VPN	L2Extension
ls_id	Pre-created logical switch id for Segment This property is deprecated. The property will continue to work as expected for existing segments. The segments that are newly created with ls_id will be ignored. Sepcify pre-creted logical switch id for Segment.	string	Deprecated
mac_pool_id	Allocation mac pool associated with the Segment Mac pool id that associated with a Segment.	string
marked_for_delete	Indicates whether the intent object is marked for deletion Intent objects are not directly deleted from the system when a delete is invoked on them. They are marked for deletion and only when all the realized entities for that intent object gets deleted, the intent object is deleted. Objects that are marked for deletion are not returned in GET call. One can use the search API to get these objects.	boolean	Readonly Default: "False"
metadata_proxy_paths	Metadata Proxy Configuration Paths Policy path to metadata proxy configuration. Multiple distinct MD proxies can be configured.	array of string
overlay_id	Overlay connectivity ID for this Segment Used for overlay connectivity of segments. The overlay_id should be allocated from the pool as definied by enforcement-point. If not provided, it is auto-allocated from the default pool on the enforcement-point.	int	Minimum: 0 Maximum: 2147483647
overridden	Indicates whether this object is the overridden intent object Global intent objects cannot be modified by the user. However, certain global intent objects can be overridden locally by use of this property. In such cases, the overridden local values take precedence over the globally defined values for the properties.	boolean	Readonly Default: "False"
parent_path	Path of its parent Path of its parent	string	Readonly
path	Absolute path of this object Absolute path of this object	string	Readonly
realization_id	A unique identifier assigned by the system for realizing intent This is a UUID generated by the system for realizing the entity object. In most cases this should be same as 'unique_id' of the entity. However, in some cases this can be different because of entities have migrated thier unique identifier to NSX Policy intent objects later in the timeline and did not use unique_id for realization. Realization id is helpful for users to debug data path to correlate the configuration with corresponding intent.	string	Readonly
relative_path	Relative path of this object Path relative from its parent	string	Readonly
replication_mode	Replication mode of the Segment If this field is not set for overlay segment, then the default of MTEP will be used.	string	Enum: MTEP, SOURCE Default: "MTEP"

tags	Opaque identifiers meaningful to the API user	array of Tag	Maximum items: 30

Supported for VLAN backed segments as well as Overlay Segments. - This field is required for VLAN backed Segments. - For overlay Segments, it is auto assigned if only one transport zone exists in the enforcement point. Default transport zone is auto assigned for overlay segments if none specified.	string
type	Segment type Segment type based on configuration.	string	Readonly Enum: ROUTED, EXTENDED, ROUTED_AND_EXTENDED, DISCONNECTED
unique_id	A unique identifier assigned by the system This is a UUID generated by the GM/LM to uniquely identify entites in a federated environment. For entities that are stretched across multiple sites, the same ID will be used on all the stretched sites.	string	Readonly
