在MDS 9000交换机上配置信任点和安装证书

简介

本文档介绍在MDS交换机中配置信任点和证书的配置步骤。

背景信息

公共密钥基础设施(PKI)支持为Cisco多层导向器交换机(MDS)9000系列交换机提供获取和使用数字证书的方法，以便在网络中实现安全通信。PKI支持为IP安全(IPsec)、互联网密钥交换(IKE)和安全外壳(SSH)提供可管理性和可扩展性。

先决条件

如果尚未配置交换机主机名和IP域名，则必须配置它们。

switch# configuration terminal
switch(config)# switchname <switchName> 
SwitchName(config)# ip domain-name example.com 

注意：生成证书后更改IP主机名或IP域名可能会使证书失效。

了解几个相关关键字

信任点：本地配置的对象，包含有关受信任证书颁发机构(CA)的信息，包括本地RSA密钥对、CA公共证书和CA向交换机颁发的身份证书。  可以配置多个信任点，以注册来自多个CA的交换机身份证书。  信任点中的完整身份信息可以导出到受密码保护的PKCS12标准格式的文件。以后可将其导入同一台交换机（例如，在系统崩溃后）或替换交换机。PKCS12文件中的信息包括RSA密钥对、身份证书和CA证书（或链）。 

CA证书(CA Certificate)：这是证书颁发机构(CA)针对其自身颁发的证书。设置中可能有中间或从属CA。  在这种情况下，这也可能指中间或从属CA公共证书。

证书颁发机构(CA)：管理证书请求并向主机、网络设备或用户等实体颁发身份证书的设备。CA为此类实体提供集中密钥管理。

RSA密钥对：在交换机中通过cli生成并与信任点关联。  对于交换机上配置的每个信任点，您必须生成一个唯一的RSA密钥对并将其与信任点关联。 

认证签名请求(CSR)这是从交换机生成并发送到CA以签名的请求。CA根据此CSR发回身份证书。

身份证书：这是证书颁发机构为生成CSR的交换机签名和颁发的证书。  将CSR提交到CA后，CA或管理员会通过电子邮件或Web浏览器提供身份证书。  要将身份证书粘贴到MDS信任点，该信任点必须为标准PEM(base64)格式。

要求

根 CA.

子CA证书（如果身份证书由子CA签名）在这种情况下，还需要在交换机中添加子CA的CA证书。

身份证书

配置

第 1 步

生成RSA密钥对

switchName# configure terminal 
switchName(config)# crypto key generate rsa label <rsaKeyPairName> exportable modulus xxx  

(有效模数值为（默认）512、768、1024、1536、2048和4096)

步骤 2

创建CA信任点并将RSA密钥对与信任点关联

在生成密钥对期间未指定任何密钥时，交换机FQDN用作默认密钥标签。

switchName(config)# crypto ca trustpoint <trustpointName>
switchName(config-trustpoint)# enroll terminal 
switchName(config-trustpoint)# rsakeypair <rsaKeyPairName>

步骤 3

对信任点证书颁发机构进行身份验证

如果进行身份验证的CA不是自签名CA，则在CA身份验证步骤中需要输入证书链中所有CA的完整CA证书列表。这称为要进行身份验证的CA的CA证书链。CA证书链中的最大证书数为10。

当只有根CA

switchName# configure terminal

switchName(config)# crypto ca authenticate <trustpointName> 

input (cut & paste) CA certificate (chain) in PEM format;

质询密码不随配置一起保存。如果证书需要撤销，则需要此密码，因此您必须记住此密码。

注意：请勿使用“$”字符作为密码。  这会导致CSR失败。

从以下位置开始复制

-----BEGIN CERTIFICATE REQUEST-----

直到

-----END CERTIFICATE REQUEST-----

将此项保存在交换机外部。这需要通过邮件或其他方法转发到根CA或子CA（无论哪个标志）。  CA返回签名身份证书。

NX-OS 8.4(1)及更高版本。

作为Cisco Bug ID CSCvo43832的修复程序，在NX-OS 8.4(1)中更改了注册提示。

默认情况下，Subject Name与交换机名称相同。

注册提示还允许使用备用主题名称和多个DN字段。

注意：以数字作为示例的DN字段提示可以接受具有该字符范围的任何字符串。  例如，State DN提示符显示：

输入State[1-128]:

它采用1到128个字符之间的任意字符串。

switchName# configure terminal
