eos_system – Manage the system attributes on Arista EOS devices¶
Synopsis¶
- This module provides declarative management of node system attributes on Arista EOS devices. It provides an option to configure host system parameters or remove those parameters from the device active configuration.
Parameters¶
| Parameter | Choices/Defaults | Comments | |
|---|---|---|---|

For more information please see the EOS Platform Options guide. Specifies the password to use if required to enter privileged mode on the remote device.  If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable  ANSIBLE_NET_AUTH_PASSwill be used instead. | ||
| authorize

 | Deprecated Starting with Ansible 2.5 we recommend using  connection: network_cliandbecome: yes.This option is only required if you are using eAPI. For more information please see the EOS Platform Options guide. Instructs the module to enter privileged mode on the remote device before sending any commands.  If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable  ANSIBLE_NET_AUTHORIZEwill be used instead. | |
