Synopsis

• This module provides declarative management of hostname on Cisco IOS devices.

Parameters

Parameter		Choices/Defaults	Comments
config dictionary			A dictionary of hostname options
	hostname string		set hostname for IOS
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 ^hostname. 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 states merged, replaced and overridden have identical behaviour for this module. 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 ^hostname 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.
• This module works with connection network_cli.

Examples

# Using state: merged

# Before state:
# -------------

# router-ios#show running-config | section ^hostname
# hostname Router

# Merged play:
# ------------

- name: Apply the provided configuration
  cisco.ios.ios_hostname:
    config:
      hostname: Router1
    state: merged

# Commands Fired:
# ---------------

# "commands": [
#         "hostname Router1",
# ],

# After state:
# ------------

# router-ios#show running-config | section ^hostname
# hostname Router1

# Using state: deleted

# Before state:
# -------------

# router-ios#show running-config | section ^hostname
# hostname RouterTest

# Deleted play:
# -------------

- name: Remove all existing configuration
  cisco.ios.ios_hostname:
    state: deleted

# Commands Fired:
# ---------------

# "commands": [
#     "no hostname RouterTest",
# ],

# After state:
# ------------

# router-ios#show running-config | section ^hostname
# hostname Router

# Using state: overridden

# Before state:
# -------------

# router-ios#show running-config | section ^hostname
# hostname Router

# Overridden play:
# ----------------

- name: Override commands with provided configuration
  cisco.ios.ios_hostname:
    config:
      hostname: RouterTest
    state: overridden

# Commands Fired:
# ---------------
# "commands": [
#       "hostname RouterTest",
#     ],

# After state:
# ------------

# router-ios#show running-config | section ^hostname
# hostname RouterTest

# Using state: replaced

# Before state:
# -------------

# router-ios#show running-config | section ^hostname
# hostname RouterTest

# Replaced play:
# --------------

- name: Replace commands with provided configuration
  cisco.ios.ios_hostname:
    config:
      hostname: RouterTest
    state: replaced

# Commands Fired:
# ---------------

# "commands": [],

# After state:
# ------------

# router-ios#show running-config | section ^hostname
# hostname RouterTest

# Using state: gathered

# Before state:
# -------------

# router-ios#show running-config | section ^hostname
# hostname RouterTest

# Gathered play:
# --------------

- name: Gather listed hostname config
  cisco.ios.ios_hostname:
    state: gathered

# Module Execution Result:
# ------------------------

#   "gathered": {
#      "hostname": "RouterTest"
#     },

# Using state: rendered

# Rendered play:
# --------------

- name: Render the commands for provided configuration
  cisco.ios.ios_hostname:
    config:
      hostname: RouterTest
    state: rendered

# Module Execution Result:
# ------------------------

# "rendered": [
#     "hostname RouterTest",
# ]

# Using state: parsed

# File: parsed.cfg
# ----------------

# hostname RouterTest

# Parsed play:
# ------------

- name: Parse the provided configuration with the existing running configuration
  cisco.ios.ios_hostname:
    running_config: "{{ lookup('file', 'parsed.cfg') }}"
    state: parsed

# Module Execution Result:
# ------------------------

#  "parsed": {
#     "hostname": "RouterTest"
# }

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: ['hostname Router1']
gathered list	when state is gathered	Facts about the network resource gathered from the remote device as structured data. Sample: This output will always be in the same format as the module argspec.
parsed list	when state is parsed	The device native config provided in running_config option parsed into structured data as per module argspec. Sample: This output will always be in the same format as the module argspec.
rendered list	when state is rendered	The provided configuration in the task rendered in device-native format (offline). Sample: ['hostname Switch1']
