Synopsis

• This module provides declarative management of Layer-2 interface on Arista EOS 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.
	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, e.g. Ethernet1.
	trunk dictionary			Switchport mode trunk command to configure the interface as a Layer 2 trunk.
		native_vlan integer		Native VLAN to be configured in trunk port. It is used as the trunk native VLAN ID.
		trunk_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.
running_config string				This option is used only with state parsed. The value of this option should be the output received from the EOS 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 parsed rendered gathered	The state of the configuration after module completion

Notes

Note

• Tested against Arista EOS 4.24.6F
• This module works with connection network_cli. See https://docs.ansible.com/ansible/latest/network/user_guide/platform_eos.html

Common return values are documented here, the following are the fields unique to this module:

Key	Returned	Description
after dictionary	when changed	The resulting configuration after module execution. Sample: This output will always be in the same format as the module argspec.
before dictionary	when state is merged, replaced, overridden, deleted or purged	The configuration prior to the module execution. Sample: This output will always be in the same format as the module argspec.
commands list	when state is merged, replaced, overridden, deleted or purged	The set of commands pushed to the remote device. Sample: ['interface Ethernet1', 'switchport mode trunk', 'switchport access vlan 20']
gathered list	when state is gathered	Facts about the network resource gathered from the remote device as structured data. Sample: This output will always be in the same format as the module argspec.
parsed list	when state is parsed	The device native config provided in running_config option parsed into structured data as per module argspec. Sample: This output will always be in the same format as the module argspec.
rendered list	when state is rendered	The provided configuration in the task rendered in device-native format (offline). Sample: ['interface Ethernet1', 'switchport mode trunk', 'switchport access vlan 20']
