Question

我对ansible很陌生。我正在尝试使用直接连接GNS3模拟的cisco路由器的virtualbox（仅主机适配器）来自动化cisco路由器/交换机（当前尝试使用Cisco C3600）的原型。运行装有Ansible版本2.6.2.cp的Ubuntu Server 16.04的Virtualbox

我正在尝试运行一些基本的show命令，并使用剧本将其保存到ubuntu服务器，但是我一直收到Unknown type错误。我可以使用Ansible ad hoc命令运行show命令。

ansible 192.168.56.111 -m ios_command -a "commands='show version'" -c local -u <u_name> -k

有人可以告诉我我的剧本怎么了吗？

您应该从剧本中删除主机名，用户名和密码，并将其放入清单文件中。

[all:vars]
ansible_connection=local
ansible_python_interpreter=/usr/bin/python
#ansible_ssh_common_args='-o UserKnownHostsFile=/dev/null'
ansible_ssh_common_args='-o UserKnownHostsFile=~/.ssh/known_hosts'
ansible_ssh_common_args='-o StrictHostKeyChecking=no'
ansible_ssh_user=ciscoadmin
ansible_ssh_pass=CiScO123
device_type=cisco_ios

[learn]
192.168.56.111

接下来，更正您在剧本中的主持人陈述。

更改

hosts: 192.168.56.11

到

hosts: learning

其他一切看起来都不错。如果仍然出现错误，请确保可以从主机SSH到路由器。还要使用-vvvv来运行ansible-playbook，以获取详细信息。
