module: ce_dldp_interface
short_description: Manages interface DLDP configuration on HUAWEI CloudEngine switches.
description:
- Manages interface DLDP configuration on HUAWEI CloudEngine switches.
author:
- Zhou Zhijin (@QijunPan)
notes:
- If C(state=present, enable=disable), interface DLDP enable will be turned off and
related interface DLDP configuration will be cleared.
- If C(state=absent), only local_mac is supported to configure.
- This module requires the netconf system service be enabled on the remote device being managed.
- Recommended connection is C(netconf).
- This module also works with C(local) connections for legacy playbooks.
options:
interface:
description:
- Must be fully qualified interface name, i.e. GE1/0/1, 10GE1/0/1, 40GE1/0/22, 100GE1/0/1.
required: true
enable:
description:
- Set interface DLDP enable state.
choices: ['enable', 'disable']
mode_enable:
description:
- Set DLDP compatible-mode enable state.
choices: ['enable', 'disable']
local_mac:
description:
- Set the source MAC address for DLDP packets sent in the DLDP-compatible mode.
The value of MAC address is in H-H-H format. H contains 1 to 4 hexadecimal digits.
reset:
description:
- Specify whether reseting interface DLDP state.
choices: ['enable', 'disable']
state:
description:
- Manage the state of the resource.
default: present
choices: ['present','absent']
