NSX-T Data Center REST API

Create or update a LBPool

If a LBPool with the vpc-lb-pool-id is not already present,
create a new LBPool. If it already exists, update the
LBPool. This is a full replace.

NSX Load Balancer availability in terms of use-cases and editions is
specified in NSX Feature and Edition Guide. Please review before consuming
those APIs.
This API is only available when using VMware NSX.

LBPool (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
active_monitor_paths	Active monitor path list In case of active healthchecks, load balancer itself initiates new connections (or sends ICMP ping) to the servers periodically to check their health, completely independent of any data traffic. Active healthchecks are deactivated by default and can be activated for a server pool by binding a health monitor to the pool. If multiple active monitors are configured, the pool member status is UP only when the health check status for all the monitors are UP.	array of string
algorithm	Load balancing algorithm Load Balancing algorithm chooses a server for each new connection by going through the list of servers in the pool. Currently, following load balancing algorithms are supported with ROUND_ROBIN as the default. ROUND_ROBIN means that a server is selected in a round-robin fashion. The weight would be ignored even if it is configured. WEIGHTED_ROUND_ROBIN means that a server is selected in a weighted round-robin fashion. Default weight of 1 is used if weight is not configured. LEAST_CONNECTION means that a server is selected when it has the least number of connections. The weight would be ignored even if it is configured. Slow start would be enabled by default. WEIGHTED_LEAST_CONNECTION means that a server is selected in a weighted least connection fashion. Default weight of 1 is used if weight is not configured. Slow start would be enabled by default. IP_HASH means that consistent hash is performed on the source IP address of the incoming connection. This ensures that the same client IP address will always reach the same server as long as no server goes down or up. It may be used on the Internet to provide a best-effort stickiness to clients which refuse session cookies.	string	Enum: ROUND_ROBIN, WEIGHTED_ROUND_ROBIN, LEAST_CONNECTION, WEIGHTED_LEAST_CONNECTION, IP_HASH Default: "ROUND_ROBIN"
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
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
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 get 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"
member_group	Load balancer member setting with grouping object Load balancer pool support grouping object as dynamic pool members. When member group is defined, members setting should not be specified.	LBPoolMemberGroup
members	Load balancer pool members Server pool consists of one or more pool members. Each pool member is identified, typically, by an IP address and a port.	array of LBPoolMember
min_active_members	Minimum number of active pool members to consider pool as active A pool is considered active if there are at least certain minimum number of members.	integer	Minimum: 1 Maximum: 2147483647 Default: "1"
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 locally 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
passive_monitor_path	Passive monitor path Passive healthchecks are deactivated by default and can be activated by attaching a passive health monitor to a server pool. Each time a client connection to a pool member fails, its failed count is incremented. For pools bound to L7 virtual servers, a connection is considered to be failed and failed count is incremented if any TCP connection errors (e.g. TCP RST or failure to send data) or SSL handshake failures occur. For pools bound to L4 virtual servers, if no response is received to a TCP SYN sent to the pool member or if a TCP RST is received in response to a TCP SYN, then the pool member is considered to have failed and the failed count is incremented.	string
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 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 LBPool	string
snat_translation	Snat translation configuration Depending on the topology, Source NAT (SNAT) may be required to ensure traffic from the server destined to the client is received by the load balancer. SNAT can be enabled per pool. If SNAT is not enabled for a pool, then load balancer uses the client IP and port (spoofing) while establishing connections to the servers. This is referred to as no-SNAT or TRANSPARENT mode. By default Source NAT is enabled as LBSnatAutoMap.	LBSnatTranslation (Abstract type: pass one of the following concrete types) LBSnatAutoMap LBSnatDisabled LBSnatIpPool
tags	Opaque identifiers meaningful to the API user	array of Tag	Maximum items: 30
tcp_multiplexing_enabled	TCP multiplexing enable flag TCP multiplexing allows the same TCP connection between load balancer and the backend server to be used for sending multiple client requests from different client TCP connections.	boolean	Default: "False"
tcp_multiplexing_number	Maximum number of TCP connections for multiplexing The maximum number of TCP connections per pool that are idly kept alive for sending future client requests.	integer	Minimum: 0 Maximum: 2147483647 Default: "6"
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
