Output only. [Output Only] URL of the region where the regional interconnect attachment resides. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.

Output only. [Output Only] The current state of this attachment's functionality. Enum values ACTIVE and UNPROVISIONED are shared by DEDICATED/PRIVATE, PARTNER, and PARTNER_PROVIDER interconnect attachments, while enum values PENDING_PARTNER, PARTNER_REQUEST_RECEIVED, and PENDING_CUSTOMER are used for only PARTNER and PARTNER_PROVIDER interconnect attachments. This state can take one of the following values:

• ACTIVE: The attachment has been turned up and is ready to use.
• UNPROVISIONED: The attachment is not ready to use yet, because turnup is not complete.
• PENDING_PARTNER: A newly-created PARTNER attachment that has not yet been configured on the Partner side.
• PARTNER_REQUEST_RECEIVED: A PARTNER attachment is in the process of provisioning after a PARTNER_PROVIDER attachment was created that references it.
• PENDING_CUSTOMER: A PARTNER or PARTNER_PROVIDER attachment that is waiting for a customer to activate it.
• DEFUNCT: The attachment was deleted externally and is no longer functional. This could be because the associated Interconnect was removed, or because the other side of a Partner attachment was deleted.

Output only. [Output Only] Creation timestamp inRFC3339 text format.

The IEEE 802.1Q VLAN tag for this attachment, in the range 2-4093. Only specified at creation time.

Output only. [Output Only] IPv6 address + prefix length to be configured on the customer router subinterface for this interconnect attachment.

Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply withRFC1035. 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.

Single IPv6 address + prefix length to be configured on the cloud router interface for this interconnect attachment.

• Both candidate_cloud_router_ipv6_address and candidate_customer_router_ipv6_address fields must be set or both must be unset.
• Prefix length of both candidate_cloud_router_ipv6_address and candidate_customer_router_ipv6_address must be the same.
• Max prefix length is 126.

Optional BGP ASN for the router supplied by a Layer 3 Partner if they configured BGP on behalf of the customer. Output only for PARTNER type, input only for PARTNER_PROVIDER, not available for DEDICATED.

Input only. Length of the IPv4 subnet mask. Allowed values:

- 29 (default)
- 30

The default value is 29, except for Cross-Cloud Interconnect connections that use an InterconnectRemoteLocation with a constraints.subnetLengthRange.min equal to 30. For example, connections that use an Azure remote location fall into this category. In these cases, the default value is 30, and requesting 29 returns an error.

Where both 29 and 30 are allowed, 29 is preferred, because it gives Google Cloud Support more debugging visibility.

Provisioned bandwidth capacity for the interconnect attachment. For attachments of type DEDICATED, the user can set the bandwidth. For attachments of type PARTNER, the Google Partner that is operating the interconnect must set the bandwidth. Output only for PARTNER type, mutable for PARTNER_PROVIDER and DEDICATED, and can take one of the following values:

• BPS_50M: 50 Mbit/s
• BPS_100M: 100 Mbit/s
• BPS_200M: 200 Mbit/s
• BPS_300M: 300 Mbit/s
• BPS_400M: 400 Mbit/s
• BPS_500M: 500 Mbit/s
• BPS_1G: 1 Gbit/s
• BPS_2G: 2 Gbit/s
• BPS_5G: 5 Gbit/s
• BPS_10G: 10 Gbit/s
• BPS_20G: 20 Gbit/s
• BPS_50G: 50 Gbit/s
• BPS_100G: 100 Gbit/s
• BPS_400G: 400 Gbit/s

[Output only for type PARTNER. Input only for PARTNER_PROVIDER. Not present for DEDICATED]. The opaque identifier of a PARTNER attachment used to initiate provisioning with a selected partner. Of the form "XXXXX/region/domain"

Output only. [Output Only] The unique identifier for the resource. This identifier is defined by the server.

The stack type for this interconnect attachment to identify whether the IPv6 feature is enabled or not. If not specified, IPV4_ONLY will be used.

This field can be both set at interconnect attachments creation and update interconnect attachment operations.

The type of interconnect attachment this is, which can take one of the following values:

• DEDICATED: an attachment to a Dedicated Interconnect.

• PARTNER: an attachment to a Partner Interconnect, created by the customer.

• PARTNER_PROVIDER: an attachment to a Partner Interconnect, created by the partner.

• L2_DEDICATED: a L2 attachment to a Dedicated Interconnect.

Single IPv4 address + prefix length to be configured on the customer router interface for this interconnect attachment.

Maximum Transmission Unit (MTU), in bytes, of packets passing through this interconnect attachment. Valid values are 1440, 1460, 1500, and 8896. If not specified, the value will default to 1440.

This field is not available.

URL of the underlying Interconnect object that this attachment's traffic will traverse through.

Output only. [Output Only] IPv4 address + prefix length to be configured on Cloud Router Interface for this interconnect attachment.

An optional description of this resource.

Output only. [Output Only] Dataplane version for this InterconnectAttachment. This field is only present for Dataplane version 2 and higher. Absence of this field in the API output indicates that the Dataplane is version 1.

Determines whether this Attachment will carry packets. Not present for PARTNER_PROVIDER.

Output only. [Output Only] The current status of whether or not this interconnect attachment is functional, which can take one of the following values:

• OS_ACTIVE: The attachment has been turned up and is ready to use.
• OS_UNPROVISIONED: The attachment is not ready to use yet, because turnup is not complete.

A fingerprint for the labels being applied to this InterconnectAttachment, 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 error412 conditionNotMet.

To see the latest fingerprint, make a get() request to retrieve an InterconnectAttachment.

Input only. Desired availability domain for the attachment. Only available for type PARTNER, at creation time, and can take one of the following values:

• AVAILABILITY_DOMAIN_ANY
• AVAILABILITY_DOMAIN_1
• AVAILABILITY_DOMAIN_2

For improved reliability, customers should configure a pair of attachments, one per availability domain. The selected availability domain will be provided to the Partner via the pairing key, so that the provisioned circuit will lie in the specified domain. If not specified, the value will default to AVAILABILITY_DOMAIN_ANY.

Output only. [Output Only] Google reference ID, to be used when raising support tickets with Google or otherwise to debug backend connectivity issues. [Deprecated] This field is not used.

The field is set only for attachments on Cross-Cloud Interconnect connections. Its value is copied from the InterconnectRemoteLocation remoteService field.

This field is not available.

Single IPv4 address + prefix length to be configured on the cloud router interface for this interconnect attachment.

• Both candidate_cloud_router_ip_address and candidate_customer_router_ip_address fields must be set or both must be unset.
• Prefix length of both candidate_cloud_router_ip_address and candidate_customer_router_ip_address must be the same.
• Max prefix length is 31.

Indicates the user-supplied encryption option of this VLAN attachment (interconnectAttachment). Can only be specified at attachment creation for PARTNER or DEDICATED attachments. Possible values are:

• NONE - This is the default value, which means that the VLAN attachment carries unencrypted traffic. VMs are able to send traffic to, or receive traffic from, such a VLAN attachment.
• IPSEC - The VLAN attachment carries only encrypted traffic that is encrypted by an IPsec device, such as an HA VPN gateway or third-party IPsec VPN. VMs cannot directly send traffic to, or receive traffic from, such a VLAN attachment. To use HA VPN over Cloud Interconnect, the VLAN attachment must be created with this option.
