module: nxos_nxapi
version_added: "2.1"
author: "Chris Houseknecht (@chouseknecht)"
author: "Peter Sprygada (@privateip)"
short_description: Manage NXAPI configuration on an NXOS device.
description:
- Use to enable or disable NXAPI access, set the port and state
of http and https servers, and enable or disable the sandbox.
- When enabling NXAPI access the default is to enable HTTP on port
80, enable HTTPS on port 443, and enable the web based UI sandbox.
Use the options below to override the default configuration.
- Configures the NXAPI feature on devices running Cisco NXOS. The
NXAPI feature is absent from the configuration by default. Since
this module manages the NXAPI feature it only supports the use
of the C(Cli) transport.

state:
description:
- Set to started or stopped. A state of started will
enable NXAPI access, and a state of stopped will
disable or shutdown all NXAPI access.

http_port:
description:
- Configure the port with which the HTTP server will listen on
for requests. By default, NXAPI will bind the HTTP service
to the standard HTTP port 80. This argument accepts valid
port values in the range of 1 to 65535.
required: false
default: 80
http:
description:
- Controls the operating state of the HTTP protocol as one of the
underlying transports for NXAPI. By default, NXAPI will enable
the HTTP transport when the feature is first configured. To
disable the use of the HTTP transport, set the value of this
argument to False.
required: false
default: yes
choices: ['yes', 'no']
aliases: ['enable_http']
https_port:
description:
- Configure the port with which the HTTPS server will listen on
for requests. By default, NXAPI will bind the HTTPS service
to the standard HTTPS port 443. This argument accepts valid
port values in the range of 1 to 65535.
required: false
default: 443
https:
description:
- Controls the operating state of the HTTPS protocol as one of the
underlying transports for NXAPI. By default, NXAPI will disable
the HTTPS transport when the feature is first configured. To
enable the use of the HTTPS transport, set the value of this
argument to True.
required: false
default: yes
choices: ['yes', 'no']
aliases: ['enable_https']
sandbox:
description:
- The NXAPI feature provides a web base UI for developers for
entering commands. This feature is initially disabled when
the NXAPI feature is configured for the first time. When the
C(sandbox) argument is set to True, the developer sandbox URL
will accept requests and when the value is set to False, the
sandbox URL is unavailable.
required: false
default: no
choices: ['yes', 'no']
aliases: ['enable_sandbox']
config:
description:
- The C(config) argument provides an optional argument to
specify the device running-config to used as the basis for
configuring the remote system. The C(config) argument accepts
a string value that represents the device configuration.
required: false
default: null
version_added: "2.2"
state:
description:
- The C(state) argument controls whether or not the NXAPI
feature is configured on the remote device. When the value
is C(present) the NXAPI feature configuration is present in
the device running-config. When the values is C(absent) the
feature configuration is removed from the running-config.
choices: ['present', 'absent']
required: false
default: present
