## Synopsis

- This module provides declarative management of Layer-2 interface on Cisco IOS 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 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 |  | List of allowed VLANs in a given trunk port. These are the only VLANs that will be configured on the trunk.
|  | encapsulation string | Choices: dot1q isl negotiate | Trunking encapsulation when interface is in trunking mode.
|  | native_vlan integer |  | Native VLAN to be configured in trunk port. It's used as the trunk native VLAN ID.
|  | pruning_vlans list |  | Pruning VLAN to be configured in trunk port. It's used as the trunk pruning VLAN ID.
state string | Choices: merged ← replaced overridden deleted | The state of the configuration after module completion

## Notes

Note

- Tested against Cisco IOSv Version 15.2 on VIRL

- This module works with connection `network_cli`. See IOS Platform Options.
