Updates the specified forwarding rule with the data included in the request. This method supports PATCH semantics and uses the JSON merge patch format and processing rules. Currently, you can only patch the networkTier field.

HTTP request

PATCH https://compute.googleapis.com/compute/v1/projects/{project}/global/forwardingRules/{forwardingRule}

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters

Parameters
`project`	`string` Project ID for this request.
`forwardingRule`	`string` Name of the ForwardingRule resource to patch.

project

string

Project ID for this request.

forwardingRule

string

Name of the ForwardingRule resource to patch.

Query parameters

Parameters

Parameters
`requestId`	`string` An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported (`00000000-0000-0000-0000-000000000000`).

requestId

string

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.

For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

Fields
`kind`	`string` [Output Only] Type of the resource. Always `compute#forwardingRule` for forwarding rule resources.
`id`	`string (uint64 format)` [Output Only] The unique identifier for the resource. This identifier is defined by the server.
`creationTimestamp`	`string` [Output Only] Creation timestamp in RFC3339 text format.
`name`	`string` Name of the resource; provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash. For Private Service Connect forwarding rules that forward traffic to Google APIs, the forwarding rule name must be a 1-20 characters string with lowercase letters and numbers and must start with a letter.
`description`	`string` An optional description of this resource. Provide this property when you create the resource.
`region`	`string` [Output Only] URL of the region where the regional forwarding rule resides. This field is not applicable to global forwarding rules. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.
`IPAddress`	`string` IP address for which this forwarding rule accepts traffic. When a client sends traffic to this IP address, the forwarding rule directs the traffic to the referenced `target` or `backendService`. While creating a forwarding rule, specifying an `IPAddress` is required under the following circumstances: When the `target` is set to `targetGrpcProxy` and `validateForProxyless` is set to `true`, the `IPAddress` should be set to `0.0.0.0`. When the `target` is a Private Service Connect Google APIs bundle, you must specify an `IPAddress`. Otherwise, you can optionally specify an IP address that references an existing static (reserved) IP address resource. When omitted, Google Cloud assigns an ephemeral IP address. Use one of the following formats to specify an IP address while creating a forwarding rule: IP address number, as in `100.1.2.3` IPv6 address range, as in `2600:1234::/96` Full resource URL, as in `https://www.googleapis.com/compute/v1/projects/projectId/regions/region/addresses/address-name` Partial URL or by name, as in: `projects/projectId/regions/region/addresses/address-name` `regions/region/addresses/address-name` `global/addresses/address-name` `address-name` The forwarding rule's `target` or `backendService`, and in most cases, also the `loadBalancingScheme`, determine the type of IP address that you can use. For detailed information, see IP address specifications. When reading an `IPAddress`, the API always returns the IP address number.
`IPProtocol`	`enum` The IP protocol to which this rule applies. For protocol forwarding, valid options are `TCP`, `UDP`, `ESP`, `AH`, `SCTP`, `ICMP` and `L3_DEFAULT`. The valid IP protocols are different for different load balancing products as described in Load balancing features.
`portRange`	`string` The `ports`, `portRange`, and `allPorts` fields are mutually exclusive. Only packets addressed to ports in the specified range will be forwarded to the backends configured with this forwarding rule. The `portRange` field has the following limitations: It requires that the forwarding rule `IPProtocol` be TCP, UDP, or SCTP, and It's applicable only to the following products: external passthrough Network Load Balancers, internal and external proxy Network Load Balancers, internal and external Application Load Balancers, external protocol forwarding, and Classic VPN. Some products have restrictions on what ports can be used. See port specifications for details. For external forwarding rules, two or more forwarding rules cannot use the same `[IPAddress, IPProtocol]` pair, and cannot have overlapping `portRange`s. For internal forwarding rules within the same VPC network, two or more forwarding rules cannot use the same `[IPAddress, IPProtocol]` pair, and cannot have overlapping `portRange`s. @pattern: \d+(?:-\d+)?
`ports[]`	`string` The `ports`, `portRange`, and `allPorts` fields are mutually exclusive. Only packets addressed to ports in the specified range will be forwarded to the backends configured with this forwarding rule. The `ports` field has the following limitations: It requires that the forwarding rule `IPProtocol` be TCP, UDP, or SCTP, and It's applicable only to the following products: internal passthrough Network Load Balancers, backend service-based external passthrough Network Load Balancers, and internal protocol forwarding. You can specify a list of up to five ports by number, separated by commas. The ports can be contiguous or discontiguous. For external forwarding rules, two or more forwarding rules cannot use the same `[IPAddress, IPProtocol]` pair if they share at least one port number. For internal forwarding rules within the same VPC network, two or more forwarding rules cannot use the same `[IPAddress, IPProtocol]` pair if they share at least one port number. @pattern: \d+(?:-\d+)?
`target`	`string` The URL of the target resource to receive the matched traffic. For regional forwarding rules, this target must be in the same region as the forwarding rule. For global forwarding rules, this target must be a global load balancing resource. The forwarded traffic must be of a type appropriate to the target object. For load balancers, see the "Target" column in Port specifications. For Private Service Connect forwarding rules that forward traffic to Google APIs, provide the name of a supported Google API bundle: `vpc-sc` - APIs that support VPC Service Controls. `all-apis` - All supported Google APIs. For Private Service Connect forwarding rules that forward traffic to managed services, the target must be a service attachment. The target is not mutable once set as a service attachment.
`selfLink`	`string` [Output Only] Server-defined URL for the resource.
`loadBalancingScheme`	`enum` Specifies the forwarding rule type. For more information about forwarding rules, refer to Forwarding rule concepts.
`subnetwork`	`string` This field identifies the subnetwork that the load balanced IP should belong to for this forwarding rule, used with internal load balancers and external passthrough Network Load Balancers with IPv6. If the network specified is in auto subnet mode, this field is optional. However, a subnetwork must be specified if the network is in custom subnet mode or when creating external forwarding rule with IPv6.
`network`	`string` This field is not used for global external load balancing. For internal passthrough Network Load Balancers, this field identifies the network that the load balanced IP should belong to for this forwarding rule. If the subnetwork is specified, the network of the subnetwork will be used. If neither subnetwork nor this field is specified, the default network will be used. For Private Service Connect forwarding rules that forward traffic to Google APIs, a network must be provided.
`backendService`	`string` Identifies the backend service to which the forwarding rule sends traffic. Required for internal and external passthrough Network Load Balancers; must be omitted for all other load balancer types.
`serviceDirectoryRegistrations[]`	`object` Service Directory resources to register this forwarding rule with. Currently, only supports a single Service Directory resource.
`serviceDirectoryRegistrations[].namespace`	`string` Service Directory namespace to register the forwarding rule under.
`serviceDirectoryRegistrations[].service`	`string` Service Directory service to register the forwarding rule under.
`serviceDirectoryRegistrations[].serviceDirectoryRegion`	`string` [Optional] Service Directory region to register this global forwarding rule under. Default to "us-central1". Only used for PSC for Google APIs. All PSC for Google APIs forwarding rules on the same network should use the same Service Directory region.
`serviceLabel`	`string` An optional prefix to the service name for this forwarding rule. If specified, the prefix is the first label of the fully qualified service name. The label must be 1-63 characters long, and comply with RFC1035. Specifically, the label must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash. This field is only used for internal load balancing.
`serviceName`	`string` [Output Only] The internal fully qualified service name for this forwarding rule. This field is only used for internal load balancing.
`networkTier`	`enum` This signifies the networking tier used for configuring this load balancer and can only take the following values: `PREMIUM`, `STANDARD`. For regional ForwardingRule, the valid values are `PREMIUM` and `STANDARD`. For GlobalForwardingRule, the valid value is `PREMIUM`. If this field is not specified, it is assumed to be `PREMIUM`. If `IPAddress` is specified, this value must be equal to the networkTier of the Address.
`labels`	`map (key: string, value: string)` Labels for this resource. These can only be added or modified by the `setLabels` method. Each label key/value pair must comply with RFC1035. Label values may be empty.
`labelFingerprint`	`string (bytes format)` A fingerprint for the labels being applied to this resource, which is essentially a hash of the labels set used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update labels. You must always provide an up-to-date fingerprint hash in order to update or change labels, otherwise the request will fail with error `412 conditionNotMet`. To see the latest fingerprint, make a `get()` request to retrieve a ForwardingRule. A base64-encoded string.
`ipVersion`	`enum` The IP Version that will be used by this forwarding rule. Valid options are `IPV4` or `IPV6`.
`fingerprint`	`string (bytes format)` Fingerprint of this resource. A hash of the contents stored in this object. This field is used in optimistic locking. This field will be ignored when inserting a ForwardingRule. Include the fingerprint in patch request to ensure that you do not overwrite changes that were applied from another concurrent request. To see the latest fingerprint, make a `get()` request to retrieve a ForwardingRule. A base64-encoded string.
`allPorts`	`boolean` The `ports`, `portRange`, and `allPorts` fields are mutually exclusive. Only packets addressed to ports in the specified range will be forwarded to the backends configured with this forwarding rule. The `allPorts` field has the following limitations: It requires that the forwarding rule `IPProtocol` be TCP, UDP, SCTP, or L3_DEFAULT. It's applicable only to the following products: internal passthrough Network Load Balancers, backend service-based external passthrough Network Load Balancers, and internal and external protocol forwarding. Set this field to true to allow packets addressed to any port or packets lacking destination port information (for example, UDP fragments after the first fragment) to be forwarded to the backends configured with this forwarding rule. The L3_DEFAULT protocol requires `allPorts` be set to true.
`allowGlobalAccess`	`boolean` If set to true, clients can access the internal passthrough Network Load Balancers, the regional internal Application Load Balancer, and the regional internal proxy Network Load Balancer from all regions. If false, only allows access from the local region the load balancer is located at. Note that for INTERNAL_MANAGED forwarding rules, this field cannot be changed after the forwarding rule is created.
`metadataFilters[]`	`object` Opaque filter criteria used by load balancer to restrict routing configuration to a limited set of xDS compliant clients. In their xDS requests to load balancer, xDS clients present node metadata. When there is a match, the relevant configuration is made available to those proxies. Otherwise, all the resources (e.g. `TargetHttpProxy`, `UrlMap`) referenced by the `ForwardingRule` are not visible to those proxies. For each `metadataFilter` in this list, if its `filterMatchCriteria` is set to MATCH_ANY, at least one of the `filterLabel`s must match the corresponding label provided in the metadata. If its `filterMatchCriteria` is set to MATCH_ALL, then all of its `filterLabel`s must match with corresponding labels provided in the metadata. If multiple `metadataFilters are specified, all of them need to be satisfied in order to be considered a match.` `metadataFilters specified here will be applifed before those specified in the UrlMap that this ForwardingRule references.` `metadataFilters only applies to Loadbalancers that have their loadBalancingScheme` set to `INTERNAL_SELF_MANAGED`.
`metadataFilters[].filterMatchCriteria`	`enum` Specifies how individual filter label matches within the list of `filterLabels` and contributes toward the overall `metadataFilter` match. Supported values are: `MATCH_ANY`: at least one of the `filterLabels` must have a matching label in the provided metadata. `MATCH_ALL`: all `filterLabels` must have matching labels in the provided metadata.
`metadataFilters[].filterLabels[]`	`object` The list of label value pairs that must match labels in the provided metadata based on `filterMatchCriteria` This list must not be empty and can have at the most 64 entries.
`metadataFilters[].filterLabels[].name`	`string` Name of metadata label. The name can have a maximum length of 1024 characters and must be at least 1 character long.
`metadataFilters[].filterLabels[].value`	`string` The value of the label must match the specified value. value can have a maximum length of 1024 characters.
`isMirroringCollector`	`boolean` Indicates whether or not this load balancer can be used as a collector for packet mirroring. To prevent mirroring loops, instances behind this load balancer will not have their traffic mirrored even if a `PacketMirroring` rule applies to them. This can only be set to true for load balancers that have their `loadBalancingScheme` set to `INTERNAL`.
`sourceIpRanges[]`	`string` If not empty, this forwarding rule will only forward the traffic when the source IP address matches one of the IP addresses or CIDR ranges set here. Note that a forwarding rule can only have up to 64 source IP ranges, and this field can only be used with a regional forwarding rule whose scheme is `EXTERNAL`. Each `sourceIpRange` entry should be either an IP address (for example, 1.2.3.4) or a CIDR range (for example, 1.2.3.0/24).
`pscConnectionId`	`string (uint64 format)` [Output Only] The PSC connection id of the PSC forwarding rule.
`pscConnectionStatus`	`enum`
`baseForwardingRule`	`string` [Output Only] The URL for the corresponding base forwarding rule. By base forwarding rule, we mean the forwarding rule that has the same IP address, protocol, and port settings with the current forwarding rule, but without sourceIPRanges specified. Always empty if the current forwarding rule does not have sourceIPRanges specified.
`allowPscGlobalAccess`	`boolean` This is used in PSC consumer ForwardingRule to control whether the PSC endpoint can be accessed from another region.
`noAutomateDnsZone`	`boolean` This is used in PSC consumer ForwardingRule to control whether it should try to auto-generate a DNS zone or not. Non-PSC forwarding rules do not use this field. Once set, this field is not mutable.
`ipCollection`	`string` Resource reference of a `PublicDelegatedPrefix`. The PDP must be a sub-PDP in EXTERNAL_IPV6_FORWARDING_RULE_CREATION mode. Use one of the following formats to specify a sub-PDP when creating an IPv6 NetLB forwarding rule using BYOIP: Full resource URL, as in `https://www.googleapis.com/compute/v1/projects/projectId/regions/region/publicDelegatedPrefixes/sub-pdp-name` Partial URL, as in: `projects/projectId/regions/region/publicDelegatedPrefixes/sub-pdp-name` `regions/region/publicDelegatedPrefixes/sub-pdp-name`

The error domain is typically the registered service name of the tool or product that generates the error. Example: "pubsub.googleapis.com". If the error is generated by some common infrastructure, the error domain must be a globally unique value that identifies the infrastructure. For Google API infrastructure, the error domain is "googleapis.com".
`error.errors[].errorDetails[].errorInfo.metadatas`	`map (key: string, value: string)` Additional structured details about this error. Keys must match /[a-z][a-zA-Z0-9-_]+/ but should ideally be lowerCamelCase. Also they must be limited to 64 characters in length. When identifying the current value of an exceeded limit, the units should be contained in the key, not the value. For example, rather than {"instanceLimit": "100/request"}, should be returned as, {"instanceLimitPerRequest": "100"}, if the client exceeds the number of instances that can be created in a single (batch) request.
`error.errors[].errorDetails[].quotaInfo`	`object`
`error.errors[].errorDetails[].quotaInfo.metricName`	`string` The Compute Engine quota metric name.

`error.errors[].errorDetails[].quotaInfo.dimensions`	`map (key: string, value: string)` The map holding related quota dimensions.
`error.errors[].errorDetails[].quotaInfo.limit`	`number` Current effective quota limit. The limit's unit depends on the quota type or metric.
`error.errors[].errorDetails[].quotaInfo.futureLimit`	`number` Future quota limit being rolled out. The limit's unit depends on the quota type or metric.
`error.errors[].errorDetails[].quotaInfo.rolloutStatus`	`enum` Rollout status of the future quota limit.
`error.errors[].errorDetails[].help`	`object`
`error.errors[].errorDetails[].help.links[]`	`object` URL(s) pointing to additional information on handling the current error.
`error.errors[].errorDetails[].help.links[].description`	`string` Describes what the link offers.

`error.errors[].errorDetails[].localizedMessage`	`object`
`error.errors[].errorDetails[].localizedMessage.locale`	`string` The locale used following the specification defined at https://www.rfc-editor.org/rfc/bcp/bcp47.txt. Examples are: "en-US", "fr-CH", "es-MX"
`error.errors[].errorDetails[].localizedMessage.message`	`string` The localized error message in the above locale.
`warnings[]`	`object` [Output Only] If warning messages are generated during processing of the operation, this field will be populated.
`warnings[].code`	`enum` [Output Only] A warning code, if applicable. For example, Compute Engine returns `NO_RESULTS_ON_PAGE` if there are no results in the response.
`warnings[].message`	`string` [Output Only] A human-readable description of the warning code.
`warnings[].data[]`	`object` [Output Only] Metadata about this warning in `key: value` format. For example: "data": [ { "key": "scope", "value": "zones/us-east1-d" }
`warnings[].data[].key`	`string` [Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be `scope` and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
`warnings[].data[].value`	`string` [Output Only] A warning data value corresponding to the key.
`httpErrorStatusCode`	`integer` [Output Only] If the operation fails, this field contains the HTTP error status code that was returned. For example, a `404` means the resource was not found.
`httpErrorMessage`	`string` [Output Only] If the operation fails, this field contains the HTTP error message that was returned, such as `NOT FOUND`.
`selfLink`	`string` [Output Only] Server-defined URL for the resource.
`region`	`string` [Output Only] The URL of the region where the operation resides. Only applicable when performing regional operations.
`description`	`string` [Output Only] A textual description of the operation, which is set when the operation is created.
`operationGroupId`	`string` [Output Only] An ID that represents a group of operations, such as when a group of operations results from a `bulkInsert` API request.
Union field `metadata`. [Output Only] Service-specific metadata attached to this operation. `metadata` can be only one of the following:
`setCommonInstanceMetadataOperationMetadata`	`object` [Output Only] If the operation is for projects.setCommonInstanceMetadata, this field will contain information on all underlying zonal actions and their state.
`setCommonInstanceMetadataOperationMetadata.clientOperationId`	`string` [Output Only] The client operation id.
`setCommonInstanceMetadataOperationMetadata.perLocationOperations[]`	`map (key: string, value: object)` [Output Only] Status information per location (location name is key). Example key: zones/us-central1-a
`setCommonInstanceMetadataOperationMetadata.perLocationOperations[].state`	`enum` [Output Only] Status of the action, which can be one of the following: `PROPAGATING`, `PROPAGATED`, `ABANDONED`, `FAILED`, or `DONE`.
`setCommonInstanceMetadataOperationMetadata.perLocationOperations[].error`	`object` [Output Only] If state is `ABANDONED` or `FAILED`, this field is populated.
`setCommonInstanceMetadataOperationMetadata.perLocationOperations[].error.code`	`integer` The status code, which should be an enum value of `google.rpc.Code`.
`setCommonInstanceMetadataOperationMetadata.perLocationOperations[].error.message`	`string` A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the `google.rpc.Status.details` field, or localized by the client.
`setCommonInstanceMetadataOperationMetadata.perLocationOperations[].error.details[]`	`object` A list of messages that carry the error details. There is a common set of message types for APIs to use. An object containing fields of an arbitrary type. An additional field `"@type"` contains a URI identifying the type. Example: `{ "id": 1234, "@type": "types.example.com/standard/id" }`.
