Nesta página, descrevemos como receber as chaves MACsec para
o MACsec para o Cloud Interconnect.
O MACsec para o Cloud Interconnect gera valores de chave de associação de conectividade (CAK, na sigla em inglês) do GCM-AES-256 e valores de nome de chave de associação de conectividade (CKN, na sigla em inglês). Você usa os valores que o MACsec para o Cloud Interconnect gera quando configura seu roteador local. É possível conseguir os valores a qualquer momento depois de configurar as chaves pré-compartilhadas na sua conexão do Cloud Interconnect.
Se você optar por usar papéis personalizados, verifique se o papel personalizado para
administrar o MACsec para o Cloud Interconnect inclui a
permissão compute.interconnects.getMacsecConfig do IAM.
Receber chaves pré-compartilhadas
Selecione uma das seguintes opções:
Console
No console do Google Cloud, acesse a guia Conexões
físicas do Cloud Interconnect.
Na guia MACsec, acesse a seção Chaves pré-compartilhadas, encontre o
nome da chave pré-compartilhada e clique em Visualizar. Uma janela exibe a chave de associação de conectividade (CAK) e o nome da chave de associação de conectividade (CKN). Clique no botão Copy para copiar cada valor para a
área de transferência do computador.

You\nuse the values that MACsec for Cloud Interconnect generates when you\nconfigure your on-premises router. You can get the values at any time after\nconfiguring pre-shared keys on your Cloud Interconnect connection.\n\nFor more information, see\n[Configure your on-premises router](/network-connectivity/docs/interconnect/how-to/macsec/set-up-macsec#configure-your-on-premises-router).\n\nRequired roles\n--------------\n\n\nTo get the permissions that\nyou need to retrieve MACsec keys,\n\nask your administrator to grant you the\n\n\n[Compute Network Admin](/iam/docs/roles-permissions/compute#compute.networkAdmin) (`roles/compute.networkAdmin`)\nIAM role on your project.\n\n\nFor more information about granting roles, see [Manage access to projects, folders, and organizations](/iam/docs/granting-changing-revoking-access).\n\n\nYou might also be able to get\nthe required permissions through [custom\nroles](/iam/docs/creating-custom-roles) or other [predefined\nroles](/iam/docs/roles-overview#predefined).\n\nIf you choose to use custom roles, ensure that your custom role for\nadministrating MACsec for Cloud Interconnect includes the\n`compute.interconnects.getMacsecConfig` IAM permission.\n\nGet pre-shared keys\n-------------------\n\nSelect one of the following options: \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. Select the connection that you want to view.\n\n3. On the **MACsec** tab, go to the **Pre-shared keys** section and find the\n name of the pre-shared key, and then click **View** . A window displays the\n connectivity association key (**CAK** ) and the connectivity association\n key name (**CKN** ). Click the **Copy** button to copy each value to your\n computer's clipboard.\n\n4. Click **Close**.\n\n### gcloud\n\nRun the following command: \n\n gcloud compute interconnects macsec get-config \u003cvar translate=\"no\"\u003eINTERCONNECT_CONNECTION_NAME\u003c/var\u003e\n\nReplace \u003cvar translate=\"no\"\u003eINTERCONNECT_CONNECTION_NAME\u003c/var\u003e with the name of your\nCloud Interconnect connection.\n\nThe output is similar to the following: \n\n preSharedKeys:\n - cak: 0123456789abcdef...0123456789abcdef\n ckn: 0101016789abcdef...0123456789abcdef\n name: key1\n startTime: 2023-07-01T21:00:01.000Z\n\nWhat's next?\n------------\n\n- [Rotate MACsec\n keys](/network-connectivity/docs/interconnect/how-to/macsec/rotate-macsec-keys)\n- [View MACsec status](/network-connectivity/docs/interconnect/how-to/macsec/view-macsec-status)\n- [Troubleshoot MACsec](/network-connectivity/docs/interconnect/how-to/macsec/troubleshoot-macsec)"]]
