cisco.ios.ios_l2_interfaces module – Resource Module to configure L2 interfaces.

Note

This module is part of the cisco.ios collection (version 4.0.0).

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_l2_interfaces.

New in cisco.ios 1.0.0

Synopsis

  • This module provides declarative management of Layer-2 interface on Cisco IOS devices.

Parameters

Parameter

Comments

config

list / elements=dictionary

A dictionary of Layer-2 interface options

access

dictionary

Switchport mode access command to configure the interface as a layer 2 access.

vlan

integer

Configure given VLAN in access port. It’s used as the access VLAN ID.

vlan_name

string

Set VLAN when interface is in access mode.

mode

string

Mode in which interface needs to be configured.

An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode.

Choices:

  • "access"

  • "trunk"

name

string / required

Full name of the interface excluding any logical unit number, i.e. GigabitEthernet0/1.

trunk

dictionary

Switchport mode trunk command to configure the interface as a Layer 2 trunk. Note The encapsulation is always set to dot1q.

allowed_vlans

list / elements=string

List of allowed VLANs in a given trunk port. These are the only VLANs that will be configured on the trunk.

encapsulation

string

Trunking encapsulation when interface is in trunking mode.

Choices:

  • "dot1q"

  • "isl"

  • "negotiate"

native_vlan

integer

Native VLAN to be configured in trunk port. It’s used as the trunk native VLAN ID.

pruning_vlans

list / elements=string

Pruning VLAN to be configured in trunk port. It’s used as the trunk pruning VLAN ID.

voice

dictionary

Switchport mode voice command to configure the interface with a voice vlan.

vlan

integer

Configure given voice VLAN on access port. It’s used as the voice VLAN ID.

vlan_name

string

Set VLAN when interface is in access mode.

vlan_tag

string

Set VLAN Tag. dot1p (Priority tagged on PVID) none (Don’t tell telephone about voice vlan) untagged (Untagged on PVID)

Choices:

  • "dot1p"

  • "none"

  • "untagged"

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.

Choices:

  • "merged" ← (default)

  • "replaced"

  • "overridden"

  • "deleted"

  • "rendered"

  • "gathered"

  • "parsed"
