I can not seem to access any of my switches using this collection

[quistian]

When I try to do a simple "show run" "show version" I get the error:

No existing session.
I have the connection set to network_cli

Hi,

What switch firmware and model ?

Do you have check the log of the switch and also this part of doc ? https://github.com/aruba/aos-switch-ansible-collection#setting-environment-variables

show version

Image stamp: /ws/swbuildm/rel_beluru_qaoff/code/build/lvm(swbuildm_rel_beluru_qaoff_rel_beluru)
Dec 9 2021 22:37:35
WC.16.11.0003
591
Boot Image: Primary

Boot ROM Version: WC.16.01.0010
Active Boot ROM: Primary

It's a 2930F

[quistian]

And I am setting the environment variable:

ANSIBLE_NETWORK_GROUP_MODULES=arubaoss ansible-playbook
--inventory inventory.yml
-vvvv
aos-gen-temp.yml

$ grep NETWORK /etc/ansible/ansible.cfg
NETWORK_GROUP_MODULES=arubaoss

[quistian]

I can log into the switch manually using ssh.

[quistian]

I find I can use the arubaoss_vlan module as documented using both:
ansible_connection: local and network_cli.
I can also use the arubaoss_ntp module as documented.

I can't use the arubaoss_config or arubaoss_command modules as per the documentation.
My goal is to use the ansible collection and module(s) to save the running configuration to a local file for my 2930 and 2450 switches.

When I use the arubaoss_command module, with any set of commands e.g. show version
the error message is: No existing sessions.

When I use the arubaoss_config module as follows to save the running configuration:

- name: snarf running configuration
  arubaoss_config:
    backup: True
    backup_options:
      filename: "{{ inventory_hostname }}.cfg"
    save_when: always

I receive the error:

"msg": "unable to retrieve current config",
"stderr": "Unable to decode JSON from response to exec_command('show running-config'). Received 'None'.",

The test switch is as follows:

2930F-test(config)# show system

Any ideas what I can do to get the running configuration file for a AOS switch?

@quistian

ansible run on linux ? windows ? on the ansible runner, you can make ssh connection to the switch ?
do you have try to make a capture to see if there is ssh connection to the switch ?

do you have check switch log ?

[quistian]

There is definitely an ssh connection to the switch as I can perform the vlan and ntp commands fine.
I can definitely log in manually via ssh using the credentials given to ansibile.
I am currently using OpenBSD and ansible version 2.13.4

$ ansible --version
ansible [core 2.13.4]
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/russ/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.9/site-packages/ansible
  ansible collection location = /home/russ/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/local/bin/ansible
  python version = 3.9.15 (main, Oct 21 2022, 14:01:40) [Clang 13.0.0 ]
  jinja version = 3.1.2
  libyaml = True

I've now tried to use the config and command modules with ansible on an Ubuntu 20.04 machine. The same problem exists. The modules fail in a slightly different manner, but they still fail. The other modules e.g. the NTP ones work find in network_cli mode.

[tchiapuziowong]

@quistian you should be using ansible_connection: network_cli for arubaoss_command and arubaoss_config modules, all other modules (arubaoss_vlan, arubaoss_ntp) use ansible_connection: local

[quistian]

That's what I am doing i.e. using network_cli and using arubaoss_command as follows:

hosts: aos_sws
collections:
- arubanetworks.aos_switch
vars:
ansible_network_os: arubanetworks.aos_switch.arubaoss
ansible_connection: network_cli

tasks:
- name: Show running-config, show version commands output to a file
arubaoss_command:
commands:
- show run
output_file: "./config/{{ inventory_hostname }}.cfg"
tags: cmd

The error message is as follows:

aos-out.txt

Boot ROM Version: WC.16.01.0010 Active Boot ROM: Primary

Update to 16.11 or 16.10
Helped me in my case with my 2530 to from 16.01 to 16.11 in small update steps

[uoe-ahewittbell]

Do you have password configuration-control configured on the switch?

The reason I ask Is I've been having issues with running command / config ansible playbooks and got the same error above:
"stderr": "Unable to decode JSON from response to exec_command('show running-config'). Received 'None'.",

From my testing (using a radius auth user) I was able to get it working by disabling the password config-control.

This is on both 16.10 & 16.11
