带有 cisco ios 开关的 ansible-expect 模块

Question

如果我尝试在 YAML 文件中使用 expect 模块，如下所示：

   name: some tests
      hosts: sw-test
      gather_facts: False

      tasks:
      - name: do reload in case of "catting off"
        expect:
         command: reload in 30
         responses:
          'Reload scheduled in 30 minutes by admin on vty0 (192.168.253.20)\nProceed with reload? \[confirm\]' : y
         echo: yes

但是连接有问题：

是否可以将expect模块与cisco ios switch一起使用？ 当我使用例如“ios_command”模块时，我没有这样的问题。

Answer 1

我猜，你在这里不走运，因为你需要 expect 模块：

要求（在执行模块的主机上）
蟒蛇> = 2.6
pexpect >= 3.3

而且您的 IOS 交换机上几乎没有任何 python 和 pexpect。
