You can temporarily disable a VLAN attachment so that it stops forwarding
packets. Disabling an attachment can be useful if you want to test failover.
To test that a redundant connection can successfully serve traffic, disable
the primary Cross-Cloud Interconnect connection.
Console
In the Google Cloud console, go to the VLAN attachments tab.
On the VLAN attachment details page, click Disable. The attachment
stops forwarding packets within a minute or two. To re-enable the
attachment, click Enable.
