Ansible 2.2 思科 ios 模块出现故障，并显示消息"Failed to connect to the host via ssh"

Question

我无法在 Ansible 2.1 中运行ios_command模块来在我的思科路由器上执行命令。

我编写了一本用于在思科路由器上测试ios_command模块的手册。

以下是我写的剧本

---
  - hosts: router2
   tasks:
     - ios_command:
        username: cisco
        password: cisco
#         host: router2.3node.example.com
        commands:
          - show version
        register: output
     - debug: msg="Hello World! {{ output.stdout }}"

但剧本失败，并显示以下消息：

fatal: [router2.3node.example.com]: UNREACHABLE! => {"changed": false, 
"msg": "Failed to connect to the host via ssh.", "unreachable": true}

和价值unreachable=1

还可以在调试模式下运行时找到输出：

TASK [setup] 
*******************************************************************
Using module file /home/cisco/ansible_dev/ansible/lib/ansible/modules
/core/system/setup.py
<router2.3node.example.com> ESTABLISH SSH CONNECTION FOR USER: None

-o ControlPersist=60s -o KbdInteractiveAuthentication=no -o

keyex,hostbased,publickey -o PasswordAuthentication=no -o

fatal: [router2.3node.example.com]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh.", "unreachable": true}

如果有人尝试过相同的方法并解决了这个问题，请告诉我。
