ForwardingPolicy (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
category	A way to classify a security policy, if needed. - Distributed Firewall - Policy framework provides five pre-defined categories for classifying a security policy. They are "Ethernet","Emergency", "Infrastructure" "Environment" and "Application". There is a pre-determined order in which the policy framework manages the priority of these security policies. Ethernet category is for supporting layer 2 firewall rules. The other four categories are applicable for layer 3 rules. Amongst them, the Emergency category has the highest priority followed by Infrastructure, Environment and then Application rules. Administrator can choose to categorize a security policy into the above categories or can choose to leave it empty. If empty it will have the least precedence w.r.t the above four categories. - Edge Firewall - Policy Framework for Edge Firewall provides six pre-defined categories "Emergency", "SystemRules", "SharedPreRules", "LocalGatewayRules", "AutoServiceRules" and "Default", in order of priority of rules. All categories are allowed for Gatetway Policies that belong to 'default' Domain. However, for user created domains, category is restricted to "SharedPreRules" or "LocalGatewayRules" only. Also, the users can add/modify/delete rules from only the "SharedPreRules" and "LocalGatewayRules" categories. If user doesn't specify the category then defaulted to "Rules". System generated category is used by NSX created rules, for example BFD rules. Autoplumbed category used by NSX verticals to autoplumb data path rules. Finally, "Default" category is the placeholder default rules with lowest in the order of priority.	string
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) ChildForwardingRule
comments	SecurityPolicy lock/unlock comments Comments for security policy lock/unlock.	string
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
id	Unique identifier of this resource	string	Sortable
internal_sequence_number	Internal sequence number This field is to indicate the internal sequence number of a policy with respect to the policies across categories.	int	Readonly
is_default	Default policy flag A flag to indicate whether policy is a default policy.	boolean	Readonly
lock_modified_by	User who locked the security policy ID of the user who last modified the lock for the secruity policy.	string	Readonly
lock_modified_time	SecuirtyPolicy locked/unlocked time SecurityPolicy locked/unlocked time in epoch milliseconds.	EpochMsTimestamp	Readonly
locked	Lock a security policy Indicates whether a security policy should be locked. If the security policy is locked by a user, then no other user would be able to modify this security policy. Once the user releases the lock, other users can update this security policy.	boolean	Default: "False"
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
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 ForwardingPolicy	string
rule_count	Rule count The count of rules in the policy.	int	Readonly
rules	Rules that are a part of this ForwardingPolicy	array of ForwardingRule
scheduler_path	Path to the scheduler for time based scheduling Provides a mechanism to apply the rules in this policy for a specified time duration.	string
scope	The list of group paths where the rules in this policy will get applied. This scope will take precedence over rule level scope. Supported only for security and redirection policies. In case of RedirectionPolicy, it is expected only when the policy is NS and redirecting to service chain.	array of string	Maximum items: 128
sequence_number	Sequence number to resolve conflicts across Domains This field is used to resolve conflicts between security policies across domains. In order to change the sequence number of a policy one can fire a POST request on the policy entity with a query parameter action=revise The sequence number field will reflect the value of the computed sequence number upon execution of the above mentioned POST request. For scenarios where the administrator is using a template to update several security policies, the only way to set the sequence number is to explicitly specify the sequence number for each security policy. If no sequence number is specified in the payload, a value of 0 is assigned by default. If there are multiple policies with the same sequence number then their order is not deterministic. If a specific order of policies is desired, then one has to specify unique sequence numbers or use the POST request on the policy entity with a query parameter action=revise to let the framework assign a sequence number. The value of sequence number must be between 0 and 999,999.	int	Minimum: 0
stateful	Stateful nature of the entries within this security policy. Stateful or Stateless nature of security policy is enforced on all rules in this security policy. When it is stateful, the state of the network connects are tracked and a stateful packet inspection is performed. Layer3 security policies can be stateful or stateless. By default, they are stateful. Layer2 security policies can only be stateless.	boolean
tags	Opaque identifiers meaningful to the API user	array of Tag	Maximum items: 30
tcp_strict	Enforce strict tcp handshake before allowing data packets Ensures that a 3 way TCP handshake is done before the data packets are sent. tcp_strict=true is supported only for stateful security policies. If the tcp_strict flag is not specified and the security policy is stateful, then tcp_strict will be set to true.	boolean
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
