cisco.ios.ios_l3_interfaces

Resource module to configure L3 interfaces.

Version added: 1.0.0

Synopsis

• This module provides declarative management of Layer-3 interface on Cisco IOS devices.

Parameters

Parameter				Choices/Defaults	Comments
config list / elements=dictionary					A dictionary of Layer-3 interface options
	autostate boolean			Choices: no yes	Enable autostate determination for VLAN.
	ipv4 list / elements=dictionary				IPv4 address to be set for the Layer-3 interface mentioned in name option. The address format is <ipv4 address>/<mask>, the mask is number in range 0-32 eg. 192.168.0.1/24.
		address string			Configures the IPv4 address for Interface.
		dhcp dictionary			IP Address negotiated via DHCP.
			client_id string		Specify client-id to use.
			enable boolean	Choices: no yes	Enable dhcp.
			hostname string		Specify value for hostname option.
		dhcp_client string			Configures and specifies client-id to use over DHCP ip. Note, This option shall work only when dhcp is configured as IP. GigabitEthernet interface number This option is DEPRECATED and is replaced with dhcp which accepts dict as input this attribute will be removed after 2023-08-01.
		dhcp_hostname string			Configures and specifies value for hostname option over DHCP ip. Note, This option shall work only when dhcp is configured as IP. This option is DEPRECATED and is replaced with dhcp which accepts dict as input this attribute will be removed after 2023-08-01.
		pool string			IP Address auto-configured from a local DHCP pool.
		secondary boolean		Choices: no yes	Configures the IP address as a secondary address.
		source_interface dictionary			Enable IP processing without an explicit address
			name string		Interface name
			point_to_point boolean	Choices: no yes	Enable point-to-point connection
			poll boolean	Choices: no yes	Enable IP connected host polling
	ipv6 list / elements=dictionary				IPv6 address to be set for the Layer-3 interface mentioned in name option. The address format is <ipv6 address>/<mask>, the mask is number in range 0-128 eg. fd5d:12c9:2201:1::1/64
		address string			Configures the IPv6 address for Interface.
		anycast boolean		Choices: no yes	Configure as an anycast
		autoconfig dictionary			Obtain address using auto-configuration.
			default boolean	Choices: no yes	Insert default route.
			enable boolean	Choices: no yes	enable auto-configuration.
		cga boolean		Choices: no yes	Use CGA interface identifier
		dhcp dictionary			Obtain a ipv6 address using DHCP.
			enable boolean	Choices: no yes	Enable dhcp.
			rapid_commit boolean	Choices: no yes	Enable Rapid-Commit.
		enable boolean		Choices: no yes	Enable IPv6 on interface
		eui boolean		Choices: no yes	Use eui-64 interface identifier
		link_local boolean		Choices: no yes	Use link-local address
		segment_routing dictionary			Segment Routing submode
			default boolean	Choices: no yes	Set a command to its defaults.
			enable boolean	Choices: no yes	Enable segmented routing.
			ipv6_sr boolean	Choices: no yes	Set ipv6_sr.
	mac_address string				Manually set interface MAC address.
	name string / required				Full name of the interface excluding any logical unit number, i.e. GigabitEthernet0/1.
running_config string					This option is used only with state parsed. The value of this option should be the output received from the IOS 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 rendered gathered parsed	The state the configuration should be left in The states rendered, gathered and parsed does not perform any change on the device. The state rendered will transform the configuration in config option to platform specific CLI commands which will be returned in the rendered key within the result. For state rendered active connection to remote host is not required. The state gathered will fetch the running configuration from device and transform it into structured data in the format as per the resource module argspec and the value is returned in the gathered key within the result. The state parsed reads the configuration from running_config option and transforms it into JSON format as per the resource module parameters and the value is returned in the parsed key within the result. The value of running_config option should be the same format as the output of command show running-config | section ^interface executed on device. For state parsed active connection to remote host is not required.

Notes

Note

- Tested against Cisco IOSXE Version 17.3 on CML. - Using deleted state without config will delete all l3 attributes from all the interfaces. - This module works with connection network_cli. See https://docs.ansible.com/ansible/latest/network/user_guide/platform_ios.html - The module examples uses callback plugin (stdout_callback = yaml) to generate task output in yaml format.

Return Values

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: ['ip address 192.168.0.3 255.255.255.0', 'ipv6 address dhcp rapid-commit', 'ipv6 address fd5d:12c9:2201:1::1/64 anycast']
