为什么Mellanox 'onyx_interface‘模块失败了？

Question

我的Mellanox任务角色：

---
- name: set mellanox
  set_fact:
    ansible_network_os: 'onyx'
    ansible_connection: network_cli

- name: configure interface Eth1/2
  mellanox.onyx.onyx_interface:
    name: Eth1/2
    mtu: 1500

我的剧本：

---
- hosts: mellanox_switch
  gather_facts: no
  roles:
    - mellanox

它产生的错误(冗长的3)：

The full traceback is:
  File "/tmp/ansible_mellanox.onyx.onyx_interface_payload_8h8n_8qc/ansible_mellanox.onyx.onyx_interface_payload.zip/ansible_collections/mellanox/onyx/plugins/module_utils/network/onyx/onyx.py", line 158, in get_capabilities
    capabilities = connection.get_capabilities()

        }
    },
    "msg": "show version | json-print\r\r\n% Unrecognized command \"json-print\".\r\nType \"?\" for help.\r\n\r [standalone: master] > "
}

奇怪的是，onyx_command模块工作得很好：

---
# Mellanox management
- name: set mellanox
  set_fact:
    ansible_network_os: 'onyx'
    ansible_connection: network_cli

- name: test show version
  onyx_command:
    commands: show version

不知道是什么问题。我想这可能和安装有关。

Answer 1

需要将下列行添加到剧本中

  become: yes
  become_method: enable

Answer 2

为什么Mellanox onyx_interface模块失败了？

根据错误信息

show version | json-print
Unrecognized command "json-print"

原因似乎与模块源代码module_utils/network/onyx/onyx.py有关。

社区收藏Mellanox Onyx模块模块管理Mellanox ONYX网络设备上的接口将从他自己的模块实用程序中导入(参见modules/onyx_interface)

from ansible_collections.mellanox.onyx.plugins.module_utils.network.onyx.onyx import BaseOnyxModule
from ansible_collections.mellanox.onyx.plugins.module_utils.network.onyx.onyx import get_interfaces_config

并尝试查找远程设备的版本和功能。

它尝试将结果输出格式化为JSON

def show_cmd(module, cmd, json_fmt=True, fail_on_error=True):
    if json_fmt:
        cmd += " | json-print"
    conn = get_connection(module)

这个特定的命令| json-print不是在远程设备上不可用，就是没有功能，或者缺少权限。这也解释了为什么命令show version只起作用。

若要缩小原因，还应尝试执行
