To create access levels, see\n[Creating a custom access level](/access-context-manager/docs/create-custom-access-level).\n\nThe values you use when creating a custom access level can be whatever makes\nsense for you, but the expression for the custom access level must be: \n\n certificateBindingState(origin, device) == CertificateBindingState.CERT_MATCHES_EXISTING_DEVICE\n\nFor example, you can use the gcloud CLI to create your custom\naccess level by running the following command: \n\n gcloud access-context-manager levels create \u003cvar translate=\"no\"\u003eLEVEL_NAME\u003c/var\u003e \\\n --title=\u003cvar translate=\"no\"\u003eTITLE\u003c/var\u003e \\\n --custom-level-spec=\u003cvar translate=\"no\"\u003eFILE\u003c/var\u003e \\\n --description=\u003cvar translate=\"no\"\u003eDESCRIPTION\u003c/var\u003e \\\n --policy=\u003cvar translate=\"no\"\u003ePOLICY_NAME\u003c/var\u003e\n\nThe content of the .yaml file referenced by \u003cvar translate=\"no\"\u003eFILE\u003c/var\u003e is the\nfollowing custom expression: \n\n expression: \"certificateBindingState(origin, device) == CertificateBindingState.CERT_MATCHES_EXISTING_DEVICE\"\n\nWhat's next\n-----------\n\n- [Enable CBA with VPC Service Controls](/chrome-enterprise-premium/docs/enable-cba-vpcsc)\n- [Enable CBA with user groups](/chrome-enterprise-premium/docs/enable-cba-user-groups)"]]
