Traffic isn't disrupted.\n\n- If you increase the number of circuits, you follow a process similar to\n [creating a connection](/network-connectivity/docs/interconnect/how-to/dedicated/provisioning-overview).\n Google sends you an LOA-CFA with your requested changes. You send this\n document to your vendor to grant them authorization to complete the work. New\n circuits aren't usable until they are provisioned and\n [tested](/network-connectivity/docs/interconnect/how-to/dedicated/testing-connections).\n\n- If you decrease the number of circuits, Google removes the requested number of\n ports from the bundle and notifies you which circuits to remove. You then\n need to contact your vendor to remove those Dedicated Interconnect connections.\n\nThe following items can't be modified for existing Dedicated Interconnect connections:\n\n- The link type on a Dedicated Interconnect connection. For example, changing the\n circuit from 10 Gpbs to 100 Gbps. If you want to migrate to\n 100 Gbps, you must first provision a new 100‑Gbps Dedicated Interconnect\n connection alongside your existing 10‑Gbps connection, and then\n migrate the traffic onto the 100‑Gbps connection.\n\n- Requested features, such as MACsec. For more information, see [MACsec\n support on existing Cloud Interconnect\n connections](/network-connectivity/docs/interconnect/concepts/macsec-overview#macsec-support-existing-connections).\n\n#### Permissions required for this task\n\nTo perform this task, you must have been granted the following permissions\n*or* the following Identity and Access Management (IAM) roles.\n\n**Permissions**\n\n- `compute.interconnects.get`\n- `compute.interconnects.update`\n\n**Roles**\n\n- `roles/owner`\n- `roles/editor`\n- `roles/compute.networkAdmin` \n\n### Console\n\n1. In the Google Cloud console, go to the Cloud Interconnect **Physical\n connections** tab.\n\n [Go to Physical connections](https://console.cloud.google.com/hybrid/interconnects/list?tab=interconnects)\n2. For the Dedicated Interconnect connection that you want to modify, select it.\n\n3. On the connection's detail page, click **Edit**.\n\n4. Modify your Dedicated Interconnect connection:\n\n - **Description**: Information about the connection.\n - **Capacity**: The total capacity of your connection, which is\n determined by the number and size of the circuits that you order.\n\n | **Note:** You can view the estimated cost of your choice in the upper-right corner of the Google Cloud console page.\n\n Select *one* of the following options:\n - 1 x 10‑Gbps circuit in 10‑Gbps increments up to 8 x 10‑Gbps (80 Gbps) circuits\n - 1 x 100‑Gbps (100 Gbps) circuit\n - 2 x 100‑Gbps (200 Gbps) circuits\n - **Technical contact**: An email address where notifications\n about this connection are sent. You don't need to enter your own\n address; you are included in all notifications. You can\n specify only one address.\n\n5. Click **Save**.\n\n6. To confirm your changes, click **Done**.\n\n### gcloud\n\nModify an existing Dedicated Interconnect connection by running the following command: \n\n```\ngcloud compute interconnects update INTERCONNECT_NAME \\\n --description=UPDATED_DESCRIPTION \\\n --noc-contact-email=UPDATED_EMAIL_CONTACT \\\n --requested-link-count=UPDATED_COUNT\n```\n\nReplace \u003cvar translate=\"no\"\u003eUPDATED_COUNT\u003c/var\u003e with the total number of circuits\nof type `link-type`.\n\nFor example, if you have a 20‑Gbps Dedicated Interconnect connection and want\nto make it 40 Gbps, use `--requested-link-count=4`.\n\nBilling for new circuits starts after they're ready to use (all\n[tests](/network-connectivity/docs/interconnect/how-to/dedicated/testing-connections)\nhave passed) or 30 days after your order is received. You aren't charged\nbefore then. You can cancel your order by reverting to the original number of\ncircuits. Billing for removed circuits stops when the LACP bundle is resized.\n\nWhat's next\n-----------\n\n- To create a Dedicated Interconnect connection, see the\n [Dedicated Interconnect provisioning overview](/network-connectivity/docs/interconnect/how-to/dedicated/provisioning-overview).\n\n- To learn more about Cloud Interconnect options, see the\n [Cloud Interconnect overview](/network-connectivity/docs/interconnect/concepts/overview).\n\n- To help you solve common issues that you might encounter when using\n Cloud Interconnect, see\n [Troubleshooting](/network-connectivity/docs/interconnect/support/troubleshooting)."]]
