module: junos_interface
version_added: "2.4"
author: "Ganesh Nalawade (@ganeshrn)"
short_description: Manage Interface on Juniper JUNOS network devices
description:
- This module provides declarative management of Interfaces
on Juniper JUNOS network devices.
options:
name:
description:
- Name of the Interface.
required: true
description:
description:
- Description of Interface.
enabled:
description:
- Configure interface link status.
speed:
description:
- Interface link speed.
mtu:
description:
- Maximum size of transmit packet.
duplex:
description:
- Interface link status.
default: auto
choices: ['full', 'half', 'auto']
tx_rate:
description:
- Transmit rate in bits per second (bps).
- This is state check parameter only.
- Supports conditionals, see L(Conditionals in Networking Modules,../network/user_guide/network_working_with_command_output.html)
rx_rate:
description:
- Receiver rate in bits per second (bps).
- This is state check parameter only.
- Supports conditionals, see L(Conditionals in Networking Modules,../network/user_guide/network_working_with_command_output.html)
neighbors:
description:
- Check the operational state of given interface C(name) for LLDP neighbor.
- The following suboptions are available.
suboptions:
host:
description:
- "LLDP neighbor host for given interface C(name)."
port:
description:
- "LLDP neighbor port to which given interface C(name) is connected."
delay:
description:
- Time in seconds to wait before checking for the operational state on remote
device. This wait is applicable for operational state argument which are
I(state) with values C(up)/C(down), I(tx_rate) and I(rx_rate).
default: 10
aggregate:
description: List of Interfaces definitions.
state:
description:
- State of the Interface configuration, C(up) idicates present and
operationally up and C(down) indicates present and operationally C(down)
default: present
choices: ['present', 'absent', 'up', 'down']
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.
