Synopsis

  • This module manages Layer-2 interfaces attributes of NX-OS Interfaces.

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.
Access mode is not shown in interface facts, so idempotency will not be maintained for switchport mode access and every time the output will come as changed=True.
name
string / required
Full name of interface, i.e. Ethernet1/1.
trunk
dictionary
Switchport mode trunk command to configure the interface as a Layer-2 trunk.
allowed_vlans
string
List of allowed VLANs in a given trunk port. These are the only VLANs that will be configured on the trunk.
native_vlan
integer
Native VLAN to be configured in trunk port. It is used as the trunk native 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 NX-OS 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
  • gathered
  • rendered
  • parsed
The state of the configuration after module completion.

Notes

Note

  • Tested against NXOS 7.3.(0)D1(1) on VIRL
