将 Cisco FC 交换机重置为出厂默认设置

在安装新的软件版本和 RCF 之前，必须清除 Cisco 交换机配置并执行基本配置。

1. 将交换机重置为出厂默认设置：
   1. 擦除现有配置：write erase
   2. 重新加载交换机软件：reload
      系统将重新启动并进入配置向导。在引导过程中，如果收到提示 Abort Auto Provisioning and continue with normal setup?(yes/no)[n]，应回答 yes 以继续。
   3. 在配置向导中，输入基本交换机设置：
      • 管理员密码
      • 交换机名称
      • 带外管理配置
      • 默认网关
      • SSH 服务（RSA）
      完成配置向导后，交换机将重新启动。
   4. 出现提示时，输入用户名和密码以登录交换机。

   以下示例显示了配置交换机时的提示和系统响应。尖括号（<<<）显示输入信息的位置。

   ---- System Admin Account Setup ----
   Do you want to enforce secure password standard (yes/no) [y]:y  <<<
   
       Enter the password for "admin": password  <<<
     Confirm the password for "admin": password  <<<
            ---- Basic System Configuration Dialog VDC: 1 ----
   
   This setup utility will guide you through the basic configuration of
   the system. Setup configures only enough connectivity for management
   of the system.
   
   Please register Cisco Nexus3000 Family devices promptly with your
   supplier. Failure to register may affect response times for initial
   service calls. Nexus3000 devices must be registered to receive
   entitled support services.
   
   Press Enter at anytime to skip a dialog. Use ctrl-c at anytime
   to skip the remaining dialogs.
   
   
   

   可以在下一组提示中输入基本信息，包括交换机名称、管理地址和网关，然后选择 RSA 类型的 SSH。

   Would you like to enter the basic configuration dialog (yes/no): yes
     Create another login account (yes/no) [n]:
     Configure read-only SNMP community string (yes/no) [n]:
     Configure read-write SNMP community string (yes/no) [n]:
     Enter the switch name : switch-name <<<
     Continue with Out-of-band (mgmt0) management configuration? (yes/no) [y]:
       Mgmt0 IPv4 address : management-IP-address  <<<
       Mgmt0 IPv4 netmask : management-IP-netmask  <<<
     Configure the default gateway? (yes/no) [y]: y <<<
       IPv4 address of the default gateway : gateway-IP-address  <<<
     Configure advanced IP options? (yes/no) [n]:
     Enable the telnet service? (yes/no) [n]:
     Enable the ssh service? (yes/no) [y]: y  <<<
       Type of ssh key you would like to generate (dsa/rsa) [rsa]: rsa <<<
       Number of rsa key bits <1024-2048> [1024]:
     Configure the ntp server? (yes/no) [n]:
     Configure default interface layer (L3/L2) [L2]:
     Configure default switchport interface state (shut/noshut) [noshut]: shut <<<
     Configure CoPP system profile (strict/moderate/lenient/dense) [strict]:
   
   

   最后一组提示即完成配置：

   The following configuration will be applied:
     password strength-check
     switchname IP_switch_A_1
   vrf context management
   ip route 0.0.0.0/0 10.10.99.1
   exit
     no feature telnet
     ssh key rsa 1024 force
     feature ssh
     system default switchport
     system default switchport shutdown
     copp profile strict
   interface mgmt0
   ip address 10.10.99.10 255.255.255.0
   no shutdown
   
   Would you like to edit the configuration? (yes/no) [n]:
   
   Use this configuration and save it? (yes/no) [y]:

2. 保存配置：

   IP_switch_A_1# copy running-config startup-config
   
3. 重新启动交换机并等待交换机重新加载：

   IP_switch_A_1# reload
   
4. 在 MetroCluster 光纤网配置中的其他三台交换机上重复上述步骤。
