A Cross-Site Interconnect\nconnection is a global resource. A global outage can prevent the diagnostics for\nCloud Interconnect from functioning properly.\n\nDiagnostics during provisioning\n-------------------------------\n\nViewing diagnostics provides you with the information required to troubleshoot\nand fix problems in your on-premises router configuration, which can be helpful\nif your Cross-Site Interconnect connection fails to progress\nthrough the provisioning process.\n\nThe diagnostics results contain different data depending on [what\nstage](#provisioning-stages) in the provisioning process your\nCross-Site Interconnect connection is in. The major and minor\nsteps are listed in the next section. This diagnostic information provides you\nwith possible next steps\nto take to help ensure that the provisioning process progresses without further\nissues.\n\nUse the [command output reference](#output-reference) to interpret diagnostic\ncommand results or the information provided in the Google Cloud console.\n\n### Provisioning stages\n\nThe Cross-Site Interconnect connection provisioning process\noccurs in the following stages. You must meet the requirements in stage 1\nbefore you can move on to stage 2:\n\n- **Stage 1, circuit connection**\n\n - The optical power state is `OK` for each link in the connection.\n- **Stage 2, production configuration**\n\n - The optical power state is `OK` for each link in the connection.\n - A temporary IP address is assigned to the untagged bundle interface. Google Cloud verifies connectivity through a ping. The test IP address is removed when the activation process is complete.\n\nUse diagnostics\n---------------\n\nTo see diagnostics information for the Cross-Site Interconnect\nconnection, follow these steps.\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.use`\n\n**Roles**\n\n- Compute Network Admin (`roles/compute.networkAdmin`) \n\n### Console\n\n1. In the Google Cloud console, go to the **Interconnect** page.\n\n\n [Go to Interconnect](https://console.cloud.google.com/hybrid/interconnects/list)\n\n \u003cbr /\u003e\n\n2. On the **Physical connections** tab, select the name of a\n Cross-Site Interconnect connection.\n\n3. Diagnostics information is in the following locations on the connection\n details page:\n\n - For warnings or errors, see the **Status** field.\n - For the provisioned capacity of the Cross-Site Interconnect, see the **Provisioned capacity** field.\n - For additional details, such as link status and light levels, see the **Link circuit info** section.\n - For details such as the effective capacity of the connection or status of its wire groups, see the **Wire groups** section.\n\n### gcloud\n\nUse the [`gcloud beta compute interconnects get-diagnostics` command](/sdk/gcloud/reference/beta/compute/interconnects/get-diagnostics): \n\n```\ngcloud beta compute interconnects get-diagnostics NAME \\\n --project=PROJECT_ID\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003eNAME\u003c/var\u003e: the name of the Cross-Site Interconnect connection in your project\n- \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e: the ID of the Google Cloud project\n\n### API\n\nUse the [`interconnects.getDiagnostics`\nmethod](/compute/docs/reference/rest/beta/interconnects/getDiagnostics): \n\n```\nGET https://compute.googleapis.com/compute/beta/projects/PROJECT_ID/global/interconnects/NAME/getDiagnostics\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e: the ID of the Google Cloud project\n- \u003cvar translate=\"no\"\u003eNAME\u003c/var\u003e: the name of the Cross-Site Interconnect connection in your project\n\nIf this command succeeds, it returns `InterconnectDiagnostics` output. To interpret the output, see the\n[command output reference](#output-reference) later in this document.\n\nCommand output reference\n------------------------\n\nThe definitions for the output parameters for the `gcloud` commands and the\n[`interconnects.getDiagnostics`](/compute/docs/reference/rest/beta/interconnects/getDiagnostics)\nAPI are listed in the following table.\n| **Note:** If you want to trigger on-premises warnings for the value of the transmitting and receiving optical power, you can take a known good optical value, give it a 10% margin, and trigger warnings relative to that value. In general, a `-7dBm` warning and a `-11dBm` alarm are good optical value estimates for most links.\n\nWhat's next\n-----------\n\n- To create a Cross-Site Interconnect connection, see the\n [Cross-Site Interconnect provisioning overview](/network-connectivity/docs/interconnect/how-to/cross-site/provisioning-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)."]]
