    Posted Feb 11, 2021 08:19 AM
    Hello ,

    Iam testing the ansible with arubaoss and got stuck at error related to REST API :


    fatal: [switch1]: FAILED! => {"changed": false, "msg": "Connection failure: Remote end closed connection without response", "status": -1, "url": "http://10.100.100.238:80/rest/v6.0/login-sessions"}


    When i tried it multiple times it worked for once using the below sample playbook and got fatal error again :

    #ansible-playbook system_attributes.yml -i switch_hosts.yml


    Control Machine running on Ubuntu server 20.xx
    Python 3.8
    Ansible 2.9.6
    Aruba Switch - 2930M-48G-PoE+
    Rest Interface Enabled

    PowerArubaSW : Powershell Module to use Aruba Switch API for Vlan, VlanPorts, LACP, LLDP...

    PowerArubaCP: Powershell Module to use ClearPass API (create NAD, Guest...)

    PowerArubaCX: Powershell Module to use ArubaCX API (get interface/vlan/ports info)..

    Yes I believe alexis is correct this may be similar to the issue seen here : https://github.com/aruba/aruba-ansible-modules/issues/117

    Try updating your switch and see if the issue persists​

    Update:
    With defaulting the unit to factory , setting up the OOBM IP, and REST enabled and with SSL disabled , it worked on the same fw :WC.16.10.0011 and created 50 tasks . ( see attached)
    So this just a plain home environment without RADIUS and TACACS , 
    But i did have issues when created a mgmt vlan and tried to achieve the same , will try to update the FW and see .

    Hi Sam!

    For AOS-Switch could you please install and use the AOS-Switch Collection ? When you run the playbook you'll have to set the proper environment variables as shown here.  

    You shouldn't have to change your playbook much besides ensuring you're including the collection that's described here: https://github.com/aruba/aos-switch-ansible-collection#example-playbook

    The only other thing I could consider with this error, could you please verify the user you're using to login to the switch has the proper permissions to execute REST API commands? Such as TACACs or RADIUS? Please try that and let us know if you're still receiving that error!

    Hi Tiffany,

    i was able to configure the switch to a certain extent , thanks for the support , i got suck at dsnoop:

    ---
    -
     hosts: switch1
     tasks:
        - name: enable dsnoop
           arubaoss_dsnoop:
           dsnoop: true

        - name: add dsnoop authorized_server
          arubaoss_dsnoop:
            command: authorized_server
            server_ip: "10.100.100.100"

        - name: add dsnoop authorized_server
          arubaoss_dsnoop:
            command: authorized_server
            server_ip: "10.200.200.200"

    Thanks Sam for the update! This does look like a bug, would you be able to open an issue on our collection so I can better track this? https://github.com/aruba/aos-switch-ansible-collection/issues

    Hello Tiffany,

    quick update on the dnoop error :
    I got the dsnoop authorized_server working with the help of Aruba TAC (PR)   he had to add  "arubaoss_required_if "  arubaoss_dsnoop.py file and reinstall the module :

    cd aruba-ansible-modules/aruba_module_installer/library/modules/network/arubaoss
    sudo nano arubaoss_dsnoop.py
    sudo python3 aruba_module_installer.py --reinstall

    Thank you Alagoutte, 
    I did it ..

    One more question - how does write memory work on this thing ?
    I mean after i issue the playbook command and its done configuring the changes on the switch , will it save /wr mem automatically or do we have to do it manually ?

    Hi Sam!

    Our modules do not automatically save the configuration but we have a couple options for saving the config.

    You can you the REST API module to backup the configuration with either the arubaoss_config_bkup or arubaoss_anycli like so:
    - name: backup running configuration to flash test1
      arubaoss_config_bkup:
        file_name: test1
        config_type: CT_RUNNING_CONFIG
    
    ### ANOTHER METHOD 
    
    - name: Execute write memory using ANYCLI API
      arubaoss_anycli:
        command: "write memory"​

    Or you can use the SSH module to execute the write memory command:
    - name: Save running configuration to flash using SSH command
      arubaoss_config:
        lines:
          - write memory
    
    - name: Save running configuration to flash using SSH command
      arubaoss_config:
        lines:
          - cfg-backup running-config config test1   ​

    To see the documentation for any of these modules enter the command below in your Ansible control machine:
    ansible-doc arubanetworks.aos_switch.<module_name>
    
    ansible-doc arubanetworks.aos_switch.arubaoss_anycli
    ansible-doc arubanetworks.aos_switch.arubaoss_config
    ansible-doc arubanetworks.aos_switch.arubaoss_cfg_backup​
