PolicyServiceChain (schema)

Name	Description	Type	Notes
_create_time	Timestamp of resource creation	EpochMsTimestamp	Readonly Sortable
_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
children	subtree for this type within policy tree subtree for this type within policy tree containing nested elements.	array of ChildPolicyConfigResource Children are not allowed for this type
description	Description of this resource	string	Maximum length: 1024 Sortable
display_name	Identifier to use when displaying entity in logs or GUI Defaults to ID if not set	string	Maximum length: 255 Sortable
failure_policy	Failure Policy Failure policy for the service defines the action to be taken i.e to allow or to block the traffic during failure scenarios.	string	Enum: ALLOW, BLOCK Default: "ALLOW"
forward_path_service_profiles	Forward path service profiles Forward path service profiles are applied to ingress traffic.	array of string	Required Maximum items: 4
id	Unique identifier of this resource	string	Sortable
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"
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
path_selection_policy	Path Selection Policy Path selection policy can be - ANY - Service Insertion is free to redirect to any service path regardless of any load balancing considerations or flow pinning. LOCAL - Preference to be given to local service insances. REMOTE - Preference to be given to the SVM co-located on the same host. ROUND_ROBIN - All active service paths are hit with equal probability.	string	Enum: ANY, LOCAL, REMOTE, ROUND_ROBIN Default: "ANY"
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
resource_type	Must be set to the value PolicyServiceChain	string
reverse_path_service_profiles	Reverse path service profiles Reverse path service profiles are applied to egress traffic and is optional. 2 different set of profiles can be defined for forward and reverse path. If not defined, the reverse of the forward path service profile is applied.	array of string	Maximum items: 4
service_segment_path	Path to service segment Path to service segment using which the traffic needs to be redirected.	array of string	Required Minimum items: 1 Maximum items: 1
tags	Opaque identifiers meaningful to the API user	array of Tag	Maximum items: 30
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
