Create or update DHCP server configuration

If DHCP server config with the dhcp-server-config-id is not already
present, create a new DHCP server config instance. If it already exists,
update the DHCP server config instance with specified attributes.

Realized entities of this API can be found using the path of Tier-0, Tier1,
or Segment where this config is applied on.

Modification of edge_cluster_path in DhcpServerConfig will lose all
existing DHCP leases.

If both the preferred_edge_paths in the DhcpServerConfig are changed
in a same PATCH API, e.g. change from [a,b] to [x,y], the current DHCP
server leases will be lost, which could cause network connectivity
issues. It is recommended to change only one member index in an update
call, e.g. from [a, b] to [a,y].

Clearing preferred_edge_paths will not reassign edge nodes from the
edge cluster. Instead, the previously-allocated edge nodes will be
retained to avoid loss of leases.
This API is available when using VMware Cloud on AWS or VMware NSX-T.

DhcpServerConfig (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
edge_cluster_path	Edge cluster path Edge cluster path. Auto assigned if only one edge cluster is configured on enforcement-point. Modifying edge cluster will reallocate DHCP server to the new edge cluster. Please note that re-allocating edge-cluster will result in losing of all exisitng DHCP lease information. Change edge cluster only when losing DHCP leases is not a real problem, e.g. cross-site migration or failover and all client hosts will be reboot and get new IP addresses.	string
id	Unique identifier of this resource	string	Sortable
lease_time	IP address lease time in seconds IP address lease time in seconds.	integer	Minimum: 60 Maximum: 4294967295 Default: "86400"
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
preferred_edge_paths	Edge node path Policy paths to edge nodes on which the DHCP servers run. The first edge node is assigned as active edge, and second one as stanby edge. If only one edge node is specified, the DHCP servers will run without HA support. When this property is not specified, edge nodes are auto-assigned during realization of the DHCP server.	array of string	Maximum items: 2
relative_path	Relative path of this object Path relative from its parent	string	Readonly
resource_type	Must be set to the value DhcpServerConfig	string
server_address	DHCP server address in CIDR format DHCP server address in CIDR format. Prefix length should be less than or equal to 30. DHCP server is deployed as DHCP relay service. This property is deprecated, use server_addresses instead. Both properties cannot be specified together with different new values.	string	Deprecated
server_addresses	DHCP server address in CIDR format DHCP server address in CIDR format. Both IPv4 and IPv6 address families are supported. Prefix length should be less than or equal to 30 for IPv4 address family and less than or equal to 126 for IPv6. When not specified, IPv4 value is auto-assigned to 100.96.0.1/30. Ignored when this object is configured at a Segment.	array of string	Maximum items: 2
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
