SYNOPSIS
gcloud alpha compute interconnects attachments l2-forwarding update-mapping NAME --vlan-key=VLAN_KEY [--appliance-ip-address=ADDRESSES] [--appliance-name=APPLIANCE_NAME] [--inner-vlan-to-appliance-mappings=[innerApplianceIpAddress=INNERAPPLIANCEIPADDRESS],[innerVlanTags=INNERVLANTAGS]] [--region=REGION] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) gcloud alpha compute interconnects attachments l2-forwarding update-mapping update vlan to ip mapping rule to an L2-forwarding attachment.
POSITIONAL ARGUMENTS
NAME
Name of the interconnect attachment to create.
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
--appliance-ip-address=ADDRESSES
A single IPv4 or IPv6 address used as the destination IP address for ingress packets that match on a VLAN tag, but do not match a more specific inner VLAN tag.
--appliance-name=APPLIANCE_NAME
The name of the L2 appliance mapping rule.
--inner-vlan-to-appliance-mappings=[innerApplianceIpAddress=INNERAPPLIANCEIPADDRESS],[innerVlanTags=INNERVLANTAGS]
A list of mapping rules from inner VLAN tags to IP addresses. If the inner VLAN is not explicitly mapped to an IP address range, the applianceIpAddress is used.
--region=REGION
Region of the interconnect attachment to create. 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.
