eos_hostname

Collection Note

This module is part of the arista.eos collection. To install the collection, use:

ansible-galaxy collection install arista.eos
Added in version 4.1.0.

Synopsis

  • This module configures and manages the attribute of hostname on Arista EOS platforms.

Parameters

Parameter Defaults / Choices Comments
config
dict
A dictionary of hostname options
config.hostname The system's hostname
running_config
str
This option is used only with state I(parsed).
The value of this option should be the output received from the EOS device by executing the command B(show running-config | section hostname).
The state I(parsed) reads the configuration from C(running_config) option and transforms it into Ansible structured data as per the resource module's argspec and the value is then returned in the I(parsed) key within the result.
state
str
Default: merged
Choices: deleted, merged, overridden, replaced, gathered, rendered, parsed
The state the configuration should be left in.
The states I(rendered), I(gathered) and I(parsed) does not perform any change on the device.
The state I(rendered) will transform the configuration in C(config) option to platform specific CLI commands which will be returned in the I(rendered) key within the result. For state I(rendered) active connection to remote host is not required.
The states I(merged), I(replaced) and I(overridden) have identical behaviour for this module.
The state I(gathered) will fetch the running configuration from device and transform it into structured data in the format as per the resource module argspec and the value is returned in the I(gathered) key within the result.
The state I(parsed) reads the configuration from C(running_config) option and transforms it into JSON format as per the resource module parameters and the value is returned in the I(parsed) key within the result. The value of C(running_config) option should be the same format as the output of command I(show running-config | section ^hostname) executed on device. For state I(parsed) active connection to remote host is not required.

Notes

Note

  • Tested against Arista EOS 4.24.60M
  • This module works with connection C(network_cli). See the L(EOS Platform Options,eos_platform_options).
