任务 3：熟悉基本的 show 命令
步骤 1：在初始化提示中选择 NO，直接进入命令行界面
Would you like to enter the initial configuration dialog? [yes/no]: no Would you like to terminate autoinstall? [yes]: 按下回车 Press RETURN to get started!
步骤 2：进入交换机的特权模式
Switch>enable Switch#
步骤 3：使用 show version 命令，可以检查交换机平台和版本信息

问题：粗体标记的内容分别描述了什么？
步骤 4：使用 show interface status，可以看到所有接口的状态列表 备注：该命令PT模拟不支持
步骤 5：使用 show running-config 可以看到交换机当前运行的配置
