module: junos_lldp
version_added: "2.4"
author: "Ganesh Nalawade (@ganeshrn)"
short_description: Manage LLDP configuration on Juniper JUNOS network devices
description:
  - This module provides declarative management of LLDP service
    on Juniper JUNOS network devices.
options:
  interval:
    description:
      - Frequency at which LLDP advertisements are sent (in seconds).
  transmit_delay:
    description:
      - Specify the number of seconds the device waits before sending
        advertisements to neighbors after a change is made in local system.
  hold_multiplier:
    description:
      - Specify the number of seconds that LLDP information is held before it is
        discarded. The multiplier value is used in combination with the
        C(interval) value.
  state:
    description:
      - Value of C(present) ensures given LLDP configuration
        is present on device and LLDP is enabled, for value of C(absent)
        LLDP configuration is deleted and LLDP is in disabled state.
        Value C(enabled) ensures LLDP protocol is enabled and LLDP configuration
        if any is configured on remote device, for value of C(disabled) it ensures
        LLDP protocol is disabled any LLDP configuration if any is still present.
    default: present
    choices: ['present', 'absent', 'enabled', 'disabled']
  active:
    description:
      - Specifies whether or not the configuration is active or deactivated
    default: True
    type: bool
requirements:
  - ncclient (>=v0.5.2)
notes:
  - This module requires the netconf system service be enabled on
    the remote device being managed.
  - Tested against vSRX JUNOS version 15.1X49-D15.4, vqfx-10000 JUNOS Version 15.1X53-D60.4.
  - Recommended connection is C(netconf). See L(the Junos OS Platform Options,../network/user_guide/platform_junos.html).
  - This module also works with C(local) connections for legacy playbooks.
