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: dot1q-tunnel access trunk fex-fabric fabricpath	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
• Unsupported for Cisco MDS
