NAME
gcloud alpha compute interconnects attachments l2-forwarding describe-mapping - describe a Compute Engine L2 forwarding interconnect attachment
SYNOPSIS
gcloud alpha compute interconnects attachments l2-forwarding describe-mapping NAME --vlan-key=VLAN_KEY [--region=REGION] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) gcloud alpha compute interconnects attachments l2-forwarding describe-mapping displays all data associated with Compute Engine interconnect attachment in a project.
POSITIONAL ARGUMENTS
NAME
Name of the interconnect attachment to describe.
REQUIRED FLAGS
--vlan-key=VLAN_KEY
Desired VLAN key for L2 forwarding mapping for the attachment. If not supplied, all mappings will be displayed.
OPTIONAL FLAGS
--region=REGION
Region of the interconnect attachment to describe. If not specified, you might be prompted to select a region (interactive mode only).

To avoid prompting when this flag is omitted, you can set the compute/region property: 

gcloud config set compute/region REGION

A list of regions can be fetched by running: 

gcloud compute regions list

To unset the property, run: 

gcloud config unset compute/region

Alternatively, the region can be stored in the environment variable CLOUDSDK_COMPUTE_REGION.

GCLOUD WIDE FLAGS
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.

Run $ gcloud help for details.

NOTES
This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist.
