ios_l2_interfaces – Manage Layer-2 interface on Cisco IOS devices

New in version 2.9.

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.
