## Synopsis

- Manages global DLDP configuration on HUAWEI CloudEngine switches.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
auth_mode - | Choices: md5 simple sha hmac-sha256 none | Specifies authentication algorithm of DLDP.
auth_pwd - |  | Specifies authentication password. The value is a string of 1 to 16 case-sensitive plaintexts or 24/32/48/108/128 case-sensitive encrypted characters. The string excludes a question mark (?).
enable - | Choices: enable disable | Set global DLDP enable state.
reset - | Choices: enable disable | Specify whether reset DLDP state of disabled interfaces.
time_internal - |  | Specifies the interval for sending Advertisement packets. The value is an integer ranging from 1 to 100, in seconds. The default interval for sending Advertisement packets is 5 seconds.
work_mode - | Choices: enhance normal | Set global DLDP work-mode.

## Notes

Note

- The relevant configurations will be deleted if DLDP is disabled using enable=disable.
- When using auth_mode=none, it will restore the default DLDP authentication mode. By default, DLDP packets are not authenticated.
- By default, the working mode of DLDP is enhance, so you are advised to use work_mode=enhance to restore default DLDP working mode.
- The default interval for sending Advertisement packets is 5 seconds, so you are advised to use time_interval=5 to restore default DLDP interval.
- This module requires the netconf system service be enabled on the remote device being managed.
- Recommended connection is `netconf`.
- This module also works with `local` connections for legacy playbooks.

## Examples

    - name: DLDP test
      hosts: cloudengine
      connection: local
      gather_facts: no
      vars:
        cli:
          host: "{{ inventory_hostname }}"
          port: "{{ ansible_ssh_port }}"
          username: "{{ username }}"
          password: "{{ password }}"
          transport: cli

      tasks:

      - name: "Configure global DLDP enable state"
        ce_dldp:
          enable: enable
          provider: "{{ cli }}"

      - name: "Configure DLDP work-mode and ensure global DLDP state is already enabled"
        ce_dldp:
          enable: enable
          work_mode: normal
          provider: "{{ cli }}"

      - name: "Configure advertisement message time interval in seconds and ensure global DLDP state is already enabled"
        ce_dldp:
          enable: enable
          time_interval: 6
          provider: "{{ cli }}"

      - name: "Configure a DLDP authentication mode and ensure global DLDP state is already enabled"
        ce_dldp:
          enable: enable
          auth_mode: md5
          auth_pwd: abc
          provider: "{{ cli }}"

      - name: "Reset DLDP state of disabled interfaces and ensure global DLDP state is already enabled"
        ce_dldp:
          enable: enable
          reset: enable
          provider: "{{ cli }}"
