I think you just need to set

`gather_facts: yes`

otherwise host-related variables, such as  
`inventory_hostname`

won’t exist when you come to use them later in your playbook.

Hope this helps,

Jon

Hi jon,

I think that’s not the reason. i can debug my variable used with register command. indeed i can debug the variable.

it seems now i have issue with regular expression and i am try to find good source how to use regular expr.

I have never used ios\_command, but my guess is that version.stdout[0] is a string not dictionary with the key Version in it.
