module: ce_ntp_auth
version_added: "2.4"
short_description: Manages NTP authentication configuration on HUAWEI CloudEngine switches.
description:
- Manages NTP authentication configuration on HUAWEI CloudEngine switches.
author:
- Zhijin Zhou (@QijunPan)
notes:
- If C(state=absent), the module will attempt to remove the given key configuration.
If a matching key configuration isn't found on the device, the module will fail.
- If C(state=absent) and C(authentication=on), authentication will be turned on.
- If C(state=absent) and C(authentication=off), authentication will be turned off.
options:
key_id:
description:
- Authentication key identifier (numeric).
required: true
auth_pwd:
description:
- Plain text with length of 1 to 255, encrypted text with length of 20 to 392.
auth_mode:
description:
- Specify authentication algorithm.
choices: ['hmac-sha256', 'md5']
auth_type:
description:
- Whether the given password is in cleartext or
has been encrypted. If in cleartext, the device
will encrypt it before storing it.
default: encrypt
choices: ['text', 'encrypt']
trusted_key:
description:
- Whether the given key is required to be supplied by a time source
for the device to synchronize to the time source.
default: 'disable'
choices: ['enable', 'disable']
authentication:
description:
- Configure ntp authentication enable or unconfigure ntp authentication enable.
choices: ['enable', 'disable']
state:
description:
- Manage the state of the resource.
default: present
choices: ['present','absent']
