I have a use case where I have set of hosts in my inventory file say inventory.txt as
[ios]
a.b.c.d
s.i.s.i
x.x.c.c
I need to check if vstack is enabled in each of these hosts, if enabled I need to disable it as a self healing process.
My Playbook :
---
- hosts: all
connection: network_cli
become: true
become_method: enable
tasks:
- name: Verify whether vstack feature is enabled
ios_command:
commands:
- show vstack config | incl Role
vars:
ansible_command_timeout: 30
register: showvstack
- debug:
var: showvstack.stdout
# when: showvstack.stdout is regex("'Role.*'")
#- name: set regex pattern
# set_fact:
# regex_pattern: "^.*Client (SmartInstall enabled).*$"
- name: Check with when condition
debug:
msg: "Vstack Enabled!!!!"
when: showvstack.stdout | join('') | match('Client (SmartInstall enabled)') or showvstack.stdout | join('') | match('Client')
- name: If vstack is enabled on switch disable vstack
ios_config:
lines:
- no vstack
when: showvstack.stdout | join('') | search('Client')

Since some cisco switches gives Role: Client and some cisco switches gives Role: Client Smart Install enabled, the above play will print vstack present even for switch which do not have vstack in it as I am searching for Client and it also takes Role: Client Smartinstall Disabled as Client string is present in it. My question is there a better way to print msg saying Vstack is present even when I have a condition saying Role: Client Smartinstall Disabled
