## Synopsis

- This module provides declarative management of node system attributes on Cisco IOS devices. It provides an option to configure host system parameters or remove those parameters from the device active configuration.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
auth_pass string |  | Deprecated Starting with Ansible 2.5 we recommend using `connection: network_cli` and `become: yes` with `become_pass`. For more information please see the IOS Platform Options guide. Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_AUTH_PASS` will be used instead.
authorize boolean | Choices: no ← yes | Deprecated Starting with Ansible 2.5 we recommend using `connection: network_cli` and `become: yes`. For more information please see the IOS Platform Options guide. Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_AUTHORIZE` will be used instead.
domain_name - |  | Configure the IP domain name on the remote device to the provided value. Value should be in the dotted name form and will be appended to the `hostname` to create a fully-qualified domain name.
domain_search - |  | Provides the list of domain suffixes to append to the hostname for the purpose of doing name resolution. This argument accepts a list of names and will be reconciled with the current active configuration on the running node.
hostname - |  | Configure the device hostname parameter. This option takes an ASCII string value.
lookup_enabled boolean | Choices: no yes | Administrative control for enabling or disabling DNS lookups. When this argument is set to True, lookups are performed and when it is set to False, lookups are not performed.
lookup_source - |  | Provides one or more source interfaces to use for performing DNS lookups. The interface provided in `lookup_source` must be a valid interface configured on the device.
name_servers - |  | List of DNS name servers by IP address to use to perform name resolution lookups. This argument accepts either a list of DNS servers See examples.
provider dictionary |  | Deprecated Starting with Ansible 2.5 we recommend using `connection: network_cli`. For more information please see the IOS Platform Options guide. A dict object containing connection details.
| auth_pass string |  | Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_AUTH_PASS` will be used instead.
| authorize boolean | Choices: no ← yes | Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_AUTHORIZE` will be used instead.
| host string / required |  | Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport.
| password string |  | Specifies the password to use to authenticate the connection to the remote device. This value is used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_PASSWORD` will be used instead.
| port integer | Default: 22 | Specifies the port to use when building the connection to the remote device.
| ssh_keyfile path |  | Specifies the SSH key to use to authenticate the connection to the remote device. This value is the path to the key used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_SSH_KEYFILE` will be used instead.
| timeout integer | Default: 10 | Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.
| username string |  | Configures the username to use to authenticate the connection to the remote device. This value is used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_USERNAME` will be used instead.
state - | Choices: present ← absent | State of the configuration values in the device's current active configuration. When set to present, the values should be configured in the device active configuration and when set to absent the values should not be in the device active configuration

## Notes

Note

- Tested against IOS 15.6
- For more information on using Ansible to manage network devices see the Ansible Network Guide
- For more information on using Ansible to manage Cisco devices see the Cisco integration page.

## Examples

    - name: configure hostname and domain name
      ios_system:
        hostname: ios01
        domain_name: test.example.com
        domain_search:
          - ansible.com
          - redhat.com
          - cisco.com

    - name: remove configuration
      ios_system:
        state: absent

    - name: configure DNS lookup sources
      ios_system:
        lookup_source: MgmtEth0/0/CPU0/0
        lookup_enabled: yes

    - name: configure name servers
      ios_system:
        name_servers:
          - 8.8.8.8
          - 8.8.4.4

## Return Values

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

Key | Returned | Description
--- | --- | ---
commands list | always | The list of configuration mode commands to send to the device Sample: ['hostname ios01', 'ip domain name test.example.com']
