    简介

    本文描述如何生成证书签名请求(CSR)和安装是结果为了用在Firepower可扩展操作系统的身份证书(FXO)机箱管理器上在Firepower 4100和9300系列设备。

    先决条件

    要求

    Cisco 建议您了解以下主题：

    • 配置从Line命令的FXO
    • 请使用CSR
    • 专用密钥基础设施(PKI)概念

    使用的组件

    本文档中的信息基于以下软件和硬件版本：

      • Firepower 4100和9300系列硬件
      • FXO版本1.1和2.0

    本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络实际，请保证您了解所有命令潜在影响。

    背景信息

    在初始配置以后，一自已签署的SSL证书生成为了用在机箱管理器Web应用程序上。因为该证书自已签署的，不会由客户端浏览器自动信任。第一次那新的客户端浏览器第一次访问机箱管理器Web接口，浏览器投掷SSL警告类似于您的连接，不私有并且要求用户接受证书，在您访问机箱管理器前。此进程允许能允许客户端浏览器委托连接的委托签字的证书认证机关将安装，并且启动Web接口没有警告。

    配置

    Note:现在没有办法生成在机箱管理器GUI的CSR。必须通过line命令执行它。

    生成 CSR

    执行这些步骤为了获取包含设备(IP地址或完全合格的域名(FQDN)允许客户端浏览器适当地识别服务器)的证书：

    • 创建钥匙圈并且选择模数大小专用密钥。

    Note:钥匙圈名称可以是所有输入。在这些示例中，使用firepower_cert。

    fp4120# scope security
fp4120 /security # create keyring firepower_cert
fp4120 /security/keyring* # set modulus <size>
fp4120 /security/keyring* # commit-buffer
    • 配置CSR字段。CSR可以生成与基本选项类似a subject-name。这提示输入证书请求密码。
    fp4120 /security/keyring # create certreq subject-name fp4120.test.local
    Certificate request password:
    Confirm certificate request password:
    • CSR可能也生成与允许信息类似在证书和组织将嵌入的现场的高级选项。
    fp4120 /security/keyring # create certreq 
fp4120 /security/keyring/certreq* # set country US
fp4120 /security/keyring/certreq* # set state California
fp4120 /security/keyring/certreq* # set locality "San Jose"
fp4120 /security/keyring/certreq* # set org-name "Cisco Systems"
fp4120 /security/keyring/certreq* # set org-unit-name TAC
fp4120 /security/keyring/certreq* # set subject-name fp4120.test.local
fp4120 /security/keyring/certreq* # commit-buffer
    • 导出CSR提供给您认证机关。复制开始的输出(和包括)-----开始证书请求----- 末端与(和包括)-----END证书请求-----.。

    导入认证机关证书链

    Note:所有证书必须在将导入的Base64格式到FXO。如果从或一系列接收的证书认证机关在一个不同的格式，您必须用一个SSL工具首先转换它例如Openssl。

    • 创建一新的信任点拿着证书链。

    Note:信任点名称名称可以是所有输入。在示例中使用firepower_chain。
