arista.eos.eos_l2_interfaces module – L2 interfaces resource module

Note

This module is part of the arista.eos collection (version 5.0.1).

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 arista.eos.

To use it in a playbook, specify: arista.eos.eos_l2_interfaces.

New in arista.eos 1.0.0

Synopsis

  • This module provides declarative management of Layer-2 interface on Arista EOS 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.

mode

string

Mode in which interface needs to be configured.

Access mode is not shown in interface facts, so idempotency will not be maintained for switchport mode access and every time the output will come as changed=True.

Choices:

  • "access"

  • "trunk"

name

string / required

Full name of interface, e.g. Ethernet1.

trunk

dictionary

Switchport mode trunk command to configure the interface as a Layer 2 trunk.

native_vlan

integer

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

trunk_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.

running_config

string

This option is used only with state parsed.

The value of this option should be the output received from the EOS 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 of the configuration after module completion

Choices:

  • "merged" ← (default)

  • "replaced"

  • "overridden"

  • "deleted"

  • "parsed"

  • "rendered"

  • "gathered"

Notes

Note

  • Tested against Arista EOS 4.24.6F

  • This module works with connection network_cli. See the EOS Platform Options.
