Synopsis 

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

Note

This module has a corresponding action plugin.

Parameters 

Parameter	Comments
config list / elements=dictionary	A dictionary of Layer-3 interface options
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	Enable dhcp. Choices: no yes
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	Configures the IP address as a secondary address. Choices: no yes
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	Configure as an anycast Choices: no yes
autoconfig dictionary	Obtain address using auto-configuration.
default boolean	Insert default route. Choices: no yes
enable boolean	enable auto-configuration. Choices: no yes
cga boolean	Use CGA interface identifier Choices: no yes
dhcp dictionary	Obtain a ipv6 address using DHCP.
enable boolean	Enable dhcp. Choices: no yes
rapid_commit boolean	Enable Rapid-Commit. Choices: no yes
eui boolean	Use eui-64 interface identifier Choices: no yes
link_local boolean	Use link-local address Choices: no yes
segment_routing dictionary	Segment Routing submode
default boolean	Set a command to its defaults. Choices: no yes
enable boolean	Enable segmented routing. Choices: no yes
ipv6_sr boolean	Set ipv6_sr. Choices: no yes
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	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. Choices: merged ← (default) replaced overridden deleted rendered gathered parsed

Notes 

Note

Tested against Cisco IOSv Version 15.6.
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

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”
