networking - 使用 junos_vlan 时 ncclient 超时

问题描述

我使用 ansible 进行网络自动化。通常一切都很好，但是当尝试在特定的瞻博网络交换机上创建 vlan 时，我得到了ncclient timed out while waiting for an rpc reply错误。我使用junos_vlan模块。

我尝试延长超时时间ansible.cfg，ansible_connection从network_cli到netconf等，但这些都没有帮助。

可以从服务器端或交换机端做些什么吗？

我读到一个人找到了编辑模块文件的解决方法： Ansible，Juniper CLI 命令。超时错误？

我可以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。设备有 JUNOS 14.1X53-D47.3固件。

有什么建议么？

这是失败的输出：

解决方案

一个人在这里为我提供了一个解决方案，我认为这可能会影响到你们中的更多人（https://www.reddit.com/r/ansible/comments/cq7joa/help_ncclient_timed_out_while_waiting_for_rpc/）

帮助我的实际上是一个建议，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！
