short_description: Manages Layer 2 switchport interfaces.
description:
- Manages Layer 2 interfaces
- Manages Layer 2 interfaces
author: Jason Edelman (@jedelman8)
notes:
- When C(state=absent), VLANs can be added/removed from trunk links and
the existing access VLAN can be 'unconfigured' to just having VLAN 1
on that interface.
- When working with trunks VLANs the keywords add/remove are always sent
in the `switchport trunk allowed vlan` command. Use verbose mode to see
commands sent.
- When C(state=unconfigured), the interface will result with having a default
Layer 2 interface, i.e. vlan 1 in access mode.
