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. extends_documentation_fragment: nxos options: 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: no 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 """ EXAMPLES = """ # Note: examples below use the following provider dict to handle # transport and authentication to the node. vars: cli: host: "{{ inventory_hostname }}" username: admin password: admin -
