This module adds shared support for Arista EOS devices using eAPI over
|
|
||||||
HTTP/S transport. It is built on module_utils/urls.py which is required
|
|
||||||
for proper operation.
|
|
||||||
|
|
||||||
In order to use this module, include it as part of a custom
|
|
||||||
module as shown below.
|
|
||||||
|
|
||||||
** Note: The order of the import statements does matter. **
|
|
||||||

||||||

||||||
from ansible.module_utils.urls import *
|
|
||||||
from ansible.module_utils.eapi import *
|
|
||||||
|
|
||||||
The eapi module provides the following common argument spec:
|
|
||||||
|
|
||||||
* host (str) - The IPv4 address or FQDN of the network device
|
|
||||||
* port (str) - Overrides the default port to use for the HTTP/S
|
|
||||||
connection. The default values are 80 for HTTP and
|
|
||||||
443 for HTTPS
|
|
||||||
* username (str) - The username to use to authenticate the HTTP/S
|
|
||||||
connection.
|
|
||||||
* password (str) - The password to use to authenticate the HTTP/S
|
|
||||||
connection.
|
|
||||||
* use_ssl (bool) - Specifies whether or not to use an encrypted (HTTPS)
|
|
||||||
connection or not. The default value is False.
|
|
||||||
* enable_mode (bool) - Specifies whether or not to enter `enable` mode
|
|
||||||
prior to executing the command list. The default value is True
|
|
||||||
* enable_password (str) - The password for entering `enable` mode
|
|
||||||
on the switch if configured.
|
|
||||||
* device (dict) - Used to send the entire set of connectin parameters
|
|
||||||
as a dict object. This argument is mutually exclusive with the
|
|
||||||
host argument
|
|
||||||
|
|
||||||
In order to communicate with Arista EOS devices, the eAPI feature
|
|
||||||
must be enabled and configured on the device.
