eos_l2_interfaces

Collection Note

This module is part of the arista.eos collection. To install the collection, use:

ansible-galaxy collection install arista.eos
Added in version 1.0.0.

Synopsis

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

Parameters

Parameter Defaults / Choices Comments
config
list / elements=dict
A dictionary of Layer-2 interface options
config.access Switchport mode access command to configure the interface as a layer 2 access.
config.mode Choices: access, trunk 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.
config.name Full name of interface, e.g. Ethernet1.
config.trunk Switchport mode trunk command to configure the interface as a Layer 2 trunk.
running_config
str
This option is used only with state I(parsed).
The value of this option should be the output received from the EOS device by executing the command B(show running-config | section ^interface).
The state I(parsed) reads the configuration from C(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 I(parsed) key within the result.
state
str
Default: merged
Choices: merged, replaced, overridden, deleted, parsed, rendered, gathered
The state of the configuration after module completion

Notes

Note

  • Tested against Arista EOS 4.24.6F
  • This module works with connection C(network_cli). See U(https://docs.ansible.com/ansible/latest/network/user_guide/platform_eos.html)
