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.
