## Synopsis

- This module manages the interface attributes of Arista EOS interfaces.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
config list |  | The provided configuration
| description string |  | Interface description
| duplex string |  | Interface link status. Applicable for Ethernet interfaces only. Values other than `auto` must also set speed. Ignored when speed is set above `1000`.

enabled
boolean

Choices:
- no
- yes ←

Administrative state of the interface.
Set the value to `true` to administratively enable the interface or `false` to disable it.

| mtu integer |  | MTU for a specific interface. Must be an even number between 576 and 9216. Applicable for Ethernet interfaces only.
| name string / required |  | Full name of the interface, e.g. GigabitEthernet1.
| speed string |  | Interface link speed. Applicable for Ethernet interfaces only.

state
string

Choices:
- merged ←
- replaced
- overridden
- deleted

The state of the configuration after module completion.

## Notes

Note

- Tested against Arista EOS 4.20.10M
- This module works with connection `network_cli`. See the EOS Platform Options.

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
after dictionary | when changed | The configuration as structured data after module completion. Sample: The configuration returned will always be in the same format of the parameters above.
before dictionary | always | The configuration as structured data prior to module invocation. Sample: The configuration returned will always be in the same format of the parameters above.
commands list | always | The set of commands pushed to the remote device. Sample: ['interface Ethernet2', 'shutdown', 'speed 10full']

## Status

- This module is not guaranteed to have a backwards compatible interface. [preview]
- This module is maintained by the Ansible Network Team. [network]
