使用junos_vlan时ncclient超时

Question

我使用ansible来实现网络自动化。通常情况下，一切都很正常，但当尝试在特定的Juniper交换机上创建虚拟局域网时，我得到了ncclient timed out while waiting for an rpc reply错误。我使用junos_vlan模块。

我尝试延长ansible.cfg的超时时间，将ansible_connection从network_cli切换到netconf，等等，但都没有效果。

从服务器端或交换机端都能做些什么吗？

我读到一个人找到了编辑模块文件的变通方法：Ansible, Juniper CLI commands. Timeout Error?

我能用同样的方法达到预期的效果吗？

我使用ansible 2.8.1和python 3.6.3。设备具有JUNOS 14.1X53-D47.3固件。

有什么建议吗？

以下是失败的输出：

一个家伙在这里给了我一个解决方案，我想这可能会影响到你们更多的人(https://www.reddit.com/r/ansible/comments/cq7joa/help_ncclient_timed_out_while_waiting_for_rpc/)

实际上，帮助我的是一个建议，将我的Ansible服务器中的ncclient版本从0.6.6降低到0.6.4，并将ansible.cfg中的超时值延长到至少120。

所以我得救了。谢谢!
