## 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
| 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_client integer |  | 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
|  | 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.

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.
| name string / required |  | Full name of the interface excluding any logical unit number, i.e. GigabitEthernet0/1.

state
string

Choices:
- merged ←
- replaced
- overridden
- deleted

The state of the configuration after module completion
