eos_l2_interfaces – Manages Layer-2 interface attributes of Arista EOS devices

New in version 2.9.

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
List of allowed VLANs in a given trunk port. These are the only VLANs that will be configured on the trunk.
state
string
    Choices:
  • merged ←
  • replaced
  • overridden
  • deleted
The state of the configuration after module completion

Notes

Note

  • Tested against Arista EOS 4.20.10M
  • This module works with connection network_cli. See the EOS Platform Options.
