You can view a list of all the VLAN attachments in your project and the details about each one. For example, you can view the name of an attachment, whether it's an attachment for Dedicated Interconnect or Partner Interconnect, and its associated Cloud Router. You can also check its Dataplane version.
View VLAN attachments and their details
Console
In the Google Cloud console, go to the Cloud Interconnect VLAN attachments tab.
Select a VLAN attachment to view its details.
gcloud
List all VLAN attachments that are in your project:
gcloud compute interconnects attachments list
Output:
NAME: my-attachment REGION: us-east1 TYPE: PARTNER INTERCONNECT: some-partner-interconnect ROUTER: my-router NAME: my-second-attachment REGION: us-west1 TYPE: DEDICATED INTERCONNECT: some-dedicated-interconnect ROUTER: my-second-router ...
Describe the VLAN attachment to view more information about it:
gcloud compute interconnects attachments describe my-attachment

Check the Dataplane version of an attachment
After you create a VLAN attachment, you can check the Dataplane version for the attachment.
You can only check the Dataplane version of a VLAN attachment with the Google Cloud CLI and the Compute Engine API. The Dataplane version of an attachment does not appear in the Google Cloud console.
You might need to verify that your attachment is using Dataplane v2 before you enable specific features such as Bidirectional Forwarding Detection (BFD).
gcloud
To check the Dataplane version of the attachment, run the following command:
gcloud compute interconnects attachments describe ATTACHMENT_NAME
Replace ATTACHMENT_NAME
with the name
of the attachment you are checking.
In the output, look for the dataplaneVersion
field with a value of 2
.
If the dataplaneVersion
field does not appear in the output,
the VLAN attachment is using version 1.
The following example output shows a VLAN attachment that uses Dataplane v2.
adminEnabled: true bandwidth: BPS_10G cloudRouterIpAddress: 169.254.132.105/29 creationTimestamp: '2022-03-04T10:08:11.526-08:00' customerRouterIpAddress: 169.254.132.106/29 dataplaneVersion: 2 id: '8542849272424426340' interconnect: https://www.googleapis.com/compute/v1/projects/customer-project/global/interconnects/my-interconnect kind: compute#interconnectAttachment mtu: 1460 name: my-attachment operationalStatus: OS_ACTIVE privateInterconnectInfo: tag8021q: 1100 region: https://www.googleapis.com/compute/v1/projects/customer-project/regions/us-west1 router: https://www.googleapis.com/compute/v1/projects/customer-project/regions/us-west1/routers/ipv6-cf-test-1 selfLink: https://www.googleapis.com/compute/v1/projects/customer-project/regions/us-west1/interconnectAttachments/my-attachment state: ACTIVE type: DEDICATED vlanTag8021q: 1100
API
Use the
interconnectAttachments.get
method to obtain the value of the dataplaneVersion
field.
GET https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/regions/REGION/interconnectAttachments/ATTACHMENT_NAME
Replace the following:
PROJECT_ID
: the project that contains the VLAN attachmentREGION
: the region where the VLAN attachment is locatedATTACHMENT_NAME
: the name of the VLAN attachment
In the output, look for the dataplaneVersion
field with a value of 2.
If the dataplaneVersion
field does not appear in the output, the
VLAN attachment is using version 1.
