YAML loop is giving me error: unable to open shell // NX_OS and IOS modules

Hi there,

I am building a virtual lab to test Ansible network modules against, Cisco Nexus and IOS devices.

I am running ansible with version 2.3.2 on Ubuntu server 16.04.3

root@ubuntu:/etc/ansible# ansible --version
ansible 2.3.2.0
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides
python version = 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609]

root@ubuntu:/etc/ansible# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04

The playbook that I am running is following:

  • hosts: ios
    tasks:
  • name: Bring down an interface
    ios_config:
    lines: no shutdown
    parents: interface {{ item }}
    with_items:
  • Ethernet1/5
  • Ethernet1/6
  • Ethernet1/7

Hostfile:

[all_routers:children]
ios
nexus

[ios]
Test-IOS-01 ansible_host=10.10.0.12
#Test-IOS-02 ansible_host=10.10.0.13

[nexus]
Test-Nexus-01 ansible_host=10.10.0.10 ansible_port=22
Test-Nexus-02 ansible_host=10.10.0.11 ansible_port=22

[all_routers:vars]
ansible_user=admin
ansible_password=admin
ansible_connection=local

Playbook:

  • hosts: ios
    tasks:
  • name: Bring down an interface
    ios_config:
    lines: shutdown
    parents: interface {{ item }}
    match: none
    with_items:
  • Ethernet1/5
  • Ethernet1/6
  • Ethernet1/7

I have tried several different network modules ( IOS and NEXUS ) against 2 different virtual hosts.

When I run the playbook, I get error everytime on the second loop variable. The first one works always fine.

root@ubuntu:/etc/ansible# ansible-playbook bring_down_interface.yaml

PLAY [ios] *********************************************************************

TASK [Gathering Facts] *********************************************************

with ansible-playbook bring_down_interface.yaml -vvvv, I can see

open_shell() returned 255 failed to connect to control socket

}
to retry, use: --limit @/etc/ansible/bring_down_interface.retry

Do you have some ideas how can I fix this matter?
