arista.eos.eos_l3_interfaces module – L3 interfaces resource module

Note

This module is part of the arista.eos collection (version 10.0.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install arista.eos.

To use it in a playbook, specify: arista.eos.eos_l3_interfaces.

New in arista.eos 1.0.0

Synopsis

• This module provides declarative management of Layer 3 interfaces on Arista EOS devices.

Parameters

Parameter	Comments
config list / elements=dictionary	A dictionary of Layer 3 interface options
ipv4 list / elements=dictionary	List of IPv4 addresses to be set for the Layer 3 interface mentioned in name option.
address string	IPv4 address to be set in the format <ipv4 address>/<mask> eg. 192.0.2.1/24, or dhcp to query DHCP for an IP address.
secondary boolean	Whether or not this address is a secondary address. Choices: false true
virtual boolean	Whether or not this address is a virtual address. Choices: false true
ipv6 list / elements=dictionary	List of IPv6 addresses to be set for the Layer 3 interface mentioned in name option.
address string	IPv6 address to be set in the address format is <ipv6 address>/<mask> eg. 2001:db8:2201:1::1/64 or auto-config to use SLAAC to chose an address.
name string / required	Full name of the interface, i.e. Ethernet1.
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	The state of the configuration after module completion Choices: "merged" ← (default) "replaced" "overridden" "deleted" "parsed" "gathered" "rendered"

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 ‘eos_l2_interfaces/eos_interfaces’ should be used for preparing the interfaces, before applying L3 configurations using this module (eos_l3_interfaces).

Return Values

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

Key	Description
after dictionary	The resulting configuration after module execution. Returned: when changed Sample: "This output will always be in the same format as the module argspec.\n"
before dictionary	The configuration prior to the module execution. Returned: when state is merged, replaced, overridden, deleted or purged Sample: "This output will always be in the same format as the module argspec.\n"
commands list / elements=string	The set of commands pushed to the remote device. Returned: when state is merged, replaced, overridden, deleted or purged Sample: ["interface Ethernet1", "ip address 198.51.100.14/24", "ipv6 address 2001:db8:feed::1/96"]
gathered list / elements=string	Facts about the network resource gathered from the remote device as structured data. Returned: when state is gathered Sample: ["This output will always be in the same format as the module argspec.\n"]
parsed list / elements=string	The device native config provided in running_config option parsed into structured data as per module argspec. Returned: when state is parsed Sample: ["This output will always be in the same format as the module argspec.\n"]
rendered list / elements=string	The provided configuration in the task rendered in device-native format (offline). Returned: when state is rendered Sample: ["interface Ethernet1", "ip address 198.51.100.14/24", "ipv6 address 2001:db8:feed::1/96"]
