Rule (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
action	Action The action to be applied to all the services The JUMP_TO_APPLICATION action is only supported for rules created in the Environment category. Once a match is hit then the rule processing will jump to the rules present in the Application category, skipping all further rules in the Environment category. If no rules match in the Application category then the default application rule will be hit. This is applicable only for DFW.	string	Enum: ALLOW, DROP, REJECT, JUMP_TO_APPLICATION
children	Subtree for this type within policy tree Subtree for this type within policy tree containing nested elements. Note that this type is applicable to be used in Hierarchical API only.	array of ChildPolicyConfigResource Children are not allowed for this type
description	Description of this resource	string	Maximum length: 1024 Sortable
destination_groups	Destination group paths We need paths as duplicate names may exist for groups under different domains. Along with paths we support IP Address of type IPv4 and IPv6. IP Address can be in one of the format(CIDR, IP Address, Range of IP Address). In order to specify all groups, use the constant "ANY". This is case insensitive. If "ANY" is used, it should be the ONLY element in the group array. Error will be thrown if ANY is used in conjunction with other values.	array of string	Maximum items: 128
destinations_excluded	Negation of destination groups If set to true, the rule gets applied on all the groups that are NOT part of the destination groups. If false, the rule applies to the destination groups	boolean	Default: "False"
direction	Direction Define direction of traffic.	string	Enum: IN, OUT, IN_OUT Default: "IN_OUT"
disabled	Flag to deactivate the rule Flag to deactivate the rule. Default is activated.	boolean	Default: "False"
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
ip_protocol	IPv4 vs IPv6 packet type Type of IP packet that should be matched while enforcing the rule. The value is set to IPV4_IPV6 for Layer3 rule if not specified. For Layer2/Ether rule the value must be null.	string	Enum: IPV4, IPV6, IPV4_IPV6
is_default	Default rule flag A flag to indicate whether rule is a default rule.	boolean	Readonly
logged	Enable logging flag Flag to enable packet logging. Default is deactivated.	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"
notes	Text for additional notes on changes User level field which will be printed in CLI and packet logs. Even though there is no limitation on length of the notes, internally notes will get truncated after 39 characters.	string	Maximum length: 2048
origin_site_id	A unique identifier assigned by the system for knowing which site owns an object This is a UUID generated by the system for knowing which site owns an object. This is used in NSX+.	string	Readonly
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"
owner_id	A unique identifier assigned by the system for the ownership of an object This is a UUID generated by the system for knowing who owns this object. This is used in NSX+.	string	Readonly
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
profiles	Layer 7 service profiles or TLS action profile Holds the list of layer 7 service profile paths. These profiles accept attributes and sub-attributes of various network services (e.g. L4 AppId, encryption algorithm, domain name, etc) as key value pairs. Instead of Layer 7 service profiles you can use a L7 access profile. One of either Layer 7 service profiles or L7 Access Profile can be used in firewall rule. In case of L7 access profile only one is allowed.	array of string	Maximum items: 128
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 their 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
remote_path	Path of the object on the remote end. This path is populated only in case of multi-site scenario. Currently it is supported only for LM objects. When LM is onboarded to multi-site platform like NAPP or GM, remote_path will be set to the globally unique path across multi-site topology . It is generated based on local site-name and uses /org tree namespace. Note: It is populated only for LM objects. Not supported on the GM.	string	Readonly
resource_type	Must be set to the value Rule	string
rule_id	Unique rule ID This is a unique 4 byte positive number that is assigned by the system. This rule id is passed all the way down to the data path. The first 1GB (1000 to 2^30) will be shared by GM and LM with zebra style striped number space. For E.g 1000 to (1Million -1) by LM, (1M - 2M-1) by GM and so on.	integer	Readonly
scope	The list of policy paths where the rule is applied LR/Edge/T0/T1/LRP etc. Note that a given rule can be applied on multiple LRs/LRPs.	array of string	Maximum items: 128
sequence_number	Sequence number of the this Rule This field is used to resolve conflicts between multiple Rules under Security or Gateway Policy for a Domain If no sequence number is specified in the payload, a value of 0 is assigned by default. If there are multiple rules with the same sequence number then their order is not deterministic. If a specific order of rules is desired, then one has to specify unique sequence numbers or use the POST request on the rule entity with a query parameter action=revise to let the framework assign a sequence number	int	Minimum: 0
service_entries	Raw services In order to specify raw services this can be used, along with services which contains path to services. This can be empty or null.	array of ServiceEntry (Abstract type: pass one of the following concrete types) ALGTypeServiceEntry EtherTypeServiceEntry ICMPTypeServiceEntry IGMPTypeServiceEntry IPProtocolServiceEntry L4PortSetServiceEntry NestedServiceServiceEntry	Maximum items: 128
services	Names of services In order to specify all services, use the constant "ANY". This is case insensitive. If "ANY" is used, it should be the ONLY element in the services array. Error will be thrown if ANY is used in conjunction with other values.	array of string	Maximum items: 128
source_groups	Source group paths We need paths as duplicate names may exist for groups under different domains. Along with paths we support IP Address of type IPv4 and IPv6. IP Address can be in one of the format(CIDR, IP Address, Range of IP Address). In order to specify all groups, use the constant "ANY". This is case insensitive. If "ANY" is used, it should be the ONLY element in the group array. Error will be thrown if ANY is used in conjunction with other values.	array of string	Maximum items: 128
sources_excluded	Negation of source groups If set to true, the rule gets applied on all the groups that are NOT part of the source groups. If false, the rule applies to the source groups	boolean	Default: "False"
tag	Tag applied on the rule User level field which will be printed in CLI and packet logs. Even though there is no limitation on length of a tag, internally tag will get truncated after 32 characters.	string
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 entities 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
