我正在使用 Ansible 中的 networktocode ntc-ansible 模块来控制 Cisco IOS 设备(目前是交换机)。我可以成功地使用 ntc_show_Command 来获取“show version”和“show ip int brief”并将结果放入本地文件中。但是当我在 ansible-playbook 命令末尾使用 -vvv 时,我会在终端中看到结构化的 JSON 输出。如何从 ntc_show_command 访问“module_args”和“响应”,即。如果我使用“show ip int brief”并且我想知道 int gi1/0/5 的状态。我怎样才能访问它?然后......我会/可以使用什么剧本命令来获取我正在寻找的特定数据?
这是我在使用 -vvv 运行剧本时可以看到的输出,但我不知道如何访问结构化数据

这是本地文件中 Show ip int brief 的输出。
Interface IP-Address OK? Method Status
Protocol
Vlan1 172.16.x.xxx YES NVRAM administratively down down
Vlan2 192.168.x.xxx YES NVRAM up up
Vlan10 10.10.yy.xxx YES NVRAM administratively down down
这是我的戏...

更新我根据以下建议更新了代码:
我取得了进步,但我似乎仍然错过了一些重要的事情。我的第一个调试语句(如下)正在输出完整的输出(此处未显示),它有效。我可以成功地将 set_fact 设置为“接口”。我可以遍历 interfaces 变量并使用 when 语句检测条件集,我将其更改为查找所有 up/up 接口。但是...我的输出(如下所示未显示您显示的详细信息。我的显示 (item=None) 对所有符合条件的项目显示为 OK,但不是您的输出显示的详细信息(您的第二个代码块在原始答案)。
更新- 我将调试变量修改为“item.intf”,现在我得到了 intf 名称,但仍然不是所有详细信息。
**问题:如何获取仅显示符合条件的接口的输出?可以将这些结构化数据保存到文件中吗?
更新 2::: 我能够使用复制模块将 {{ interfaces }} 作为结构化数据复制到文件中,但是当我尝试只显示接口而不是其余数据时,而是使用 {{ interfaces .intf }} 我得到一个错误。(见下文)
问题:如何获得仅显示接口名称的输出/文件?
问题:如何获得仅显示启动/启动的接口名称的输出/文件?
我的第二个调试语句(如下)正在输出这个,它标识了 up/up 接口: UPDATED。
