Synopsis

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

Note

This module has a corresponding action plugin.

Parameters

Parameter Choices/Defaults 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
    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.
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.
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.
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 IOSv Version 15.6.

  • Using deleted state without config will delete all l3 attributes from all the interfaces.
