cisco.ios.ios_interfaces module – Resource module to configure interfaces.

Note

This module is part of the cisco.ios collection (version 3.3.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install cisco.ios.

To use it in a playbook, specify: cisco.ios.ios_interfaces.

New in version 1.0.0: of cisco.ios

Synopsis

  • This module manages the interface attributes of Cisco IOS network devices.

Parameters

Parameter

Comments

config

list / elements=dictionary

A dictionary of interface options

description

string

Interface description.

duplex

string

Interface link status. Applicable for Ethernet interfaces only, either in half duplex, full duplex or in automatic state which negotiates the duplex automatically.

Choices:

  • full

  • half

  • auto

enabled

boolean

Administrative state of the interface.

Set the value to true to administratively enable the interface or false to disable it.

Choices:

  • no

  • yes ← (default)

mtu

integer

MTU for a specific interface. Applicable for Ethernet interfaces only.

Refer to vendor documentation for valid values.

name

string / required

Full name of interface, e.g. GigabitEthernet0/2, loopback999.

speed

string

Interface link speed. Applicable for Ethernet interfaces only.

running_config

string

This option is used only with state parsed.

The value of this option should be the output received from the IOS device by executing the command show running-config | section ^interface.

The state parsed reads the configuration from running_config option and transforms it into Ansible structured data as per the resource module’s argspec and the value is then returned in the parsed key within the result.

state

string

The state the configuration should be left in

The states rendered, gathered and parsed does not perform any change on the device.

The state rendered will transform the configuration in config option to platform specific CLI commands which will be returned in the rendered key within the result. For state rendered active connection to remote host is not required.

The state gathered will fetch the running configuration from device and transform it into structured data in the format as per the resource module argspec and the value is returned in the gathered key within the result.

The state parsed reads the configuration from running_config option and transforms it into JSON format as per the resource module parameters and the value is returned in the parsed key within the result. The value of running_config option should be the same format as the output of command show running-config | include ip route|ipv6 route executed on device. For state parsed active connection to remote host is not required.

The state purged negates virtual/logical interfaces that are specified in task from running-config.

Choices:

  • merged ← (default)

  • replaced

  • overridden

  • deleted

  • rendered

  • gathered

  • purged

  • parsed
