  • -r . admin-enabled=false
    • Determines whether this Attachment will carry packets. Not present for PARTNER_PROVIDER.
  • bandwidth=et
    • Provisioned bandwidth capacity for the interconnect attachment. For attachments of type DEDICATED, the user can set the bandwidth.

  • description=tempor
    • An optional description of this resource.
  • edge-availability-domain=sit
    • 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.
  • encryption=diam
    • 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 IPsec-encrypted Cloud Interconnect, the VLAN attachment must be created with this option. Not currently available publicly.
  • google-reference-id=amet.
    • [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.
  • id=vero
    • [Output Only] The unique identifier for the resource. This identifier is defined by the server.
  • interconnect=tempor
    • URL of the underlying Interconnect object that this attachment's traffic will traverse through.
  • ipsec-internal-addresses=est
    • A list of URLs of addresses that have been reserved for the VLAN attachment. Used only for the VLAN attachment that has the encryption option as IPSEC. The addresses must be regional internal IP address ranges. When creating an HA VPN gateway over the VLAN attachment, if the attachment is configured to use a regional internal IP address, then the VPN gateway's IP address is allocated from the IP address range specified here. For example, if the HA VPN gateway's interface 0 is paired to this VLAN attachment, then a regional internal IP address for the VPN gateway interface 0 will be allocated from the IP address specified for this VLAN attachment. If this field is not specified when creating the VLAN attachment, then later on when creating an HA VPN gateway on this VLAN attachment, the HA VPN gateway's IP address is allocated from the regional external IP address pool. Not currently available publicly.

    • The IEEE 802.1Q VLAN tag for this attachment, in the range 2-4094. Only specified at creation time.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional Method Properties

You may set the following properties to further configure the call. Please note that -p is followed by one or more key-value-pairs, and is called like this -p k1=v1 k2=v2 even though the listing below repeats the -p for completeness.

  • -p request-id=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).
