Synopsis

  • This module provides declarative management of Layer-2 interface on Cisco IOS devices.

Note

This module has a corresponding action plugin.

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.
mode
string
    Choices:
  • access
  • trunk
Mode in which interface needs to be configured.
An interface whose trunk encapsulation is "Auto" can not be configured to "trunk" mode.
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 / elements=string
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 / elements=string
Pruning VLAN to be configured in trunk port. It's used as the trunk pruning VLAN ID.
voice
dictionary
Switchport mode voice command to configure the interface with a voice vlan.
vlan
integer
Configure given voice VLAN on access port. It's used as the voice VLAN ID.
running_config
string
This option is used only with state parsed.
The value of this option should be the output received from the IOS device by executing the command show running-config | section ^interface.
The state parsed reads the configuration from running_config option and transforms it into Ansible structured data as per the resource module's argspec and the value is then returned in the parsed key within the result.
state
string
    Choices:
  • merged
  • replaced
  • overridden
  • deleted
  • rendered
  • gathered
  • parsed
The state the configuration should be left in
The states rendered, gathered and parsed does not perform any change on the device.
The state rendered will transform the configuration in config option to platform specific CLI commands which will be returned in the rendered key within the result. For state rendered active connection to remote host is not required.
The state gathered will fetch the running configuration from device and transform it into structured data in the format as per the resource module argspec and the value is returned in the gathered key within the result.
The state parsed reads the configuration from running_config option and transforms it into JSON format as per the resource module parameters and the value is returned in the parsed key within the result. The value of running_config option should be the same format as the output of command show running-config | include ip route|ipv6 route executed on device. For state parsed active connection to remote host is not required.

Notes

Note

  • Tested against Cisco IOSv Version 15.2 on VIRL.
