module: aci_tenant_ep_retention_policy
short_description: Manage End Point (EP) retention protocol policies on Cisco ACI fabrics (fv:EpRetPol)
description:
- Manage End Point (EP) retention protocol policies on Cisco ACI fabrics.
- More information from the internal APIC class I(fv:EpRetPol) at
  U(https://developer.cisco.com/docs/apic-mim-ref/).
author:
- Swetha Chunduri (@schunduri)
version_added: '2.4'
notes:
- The C(tenant) used must exist before using this module in your playbook.
  The M(aci_tenant) module can be used for this.
options:
  tenant:
    description:
    - The name of an existing tenant.
    aliases: [ tenant_name ]
  epr_policy:
    description:
    - The name of the end point retention policy.
    aliases: [ epr_name, name ]
  bounce_age:
    description:
    - Bounce Entry Aging Interval (range 150secs - 65535secs)
    - 0 is used for infinite.
    default: 630
  bounce_trigger:
    description:
    - Determines if the bounce entries are installed by RARP Flood or COOP Protocol.
    - The APIC defaults new End Point Retention Policies to C(coop).
    default: coop
  hold_interval:
    description:
    - Hold Interval (range 5secs - 65535secs).
    default: 300
  local_ep_interval:
    description:
    - Local end point Aging Interval (range 120secs - 65535secs).
    - 0 is used for infinite.
    default: 900
  remote_ep_interval:
    description:
    - Remote end point Aging Interval (range 120secs - 65535secs).
    - O is used for infinite.
    default: 300
  move_frequency:
    description:
    - Move frequency per second (range 0secs - 65535secs).
    - 0 is used for none.
    default: 256
  description:
    description:
    - Description for the End point rentention policy.
    aliases: [ descr ]
  state:
    description:
    - Use C(present) or C(absent) for adding or removing.
    - Use C(query) for listing an object or multiple objects.
    choices: [ absent, present, query ]
    default: present
