## Synopsis

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

## Parameters

Parameter | Choices/Defaults | 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.
| 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 |  | List of allowed VLANs in a given trunk port. These are the only VLANs that will be configured on the trunk.

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.
