Hi,

I have a problem with the ios_command and the C9200L switch when updating the IOS-XE. One step of the upgrade is

On step is to remove inactive IOS versions:

install remove inactive
(…)
Do you want to remove the above files? [y/n]

the part of the playbook looks like:

Error output is:

The full traceback is:

The value of prompt option is a python regex hence either handle special character in prompt correctly by using escape character or remove those characters from prompt completely.

For example:

  • name: remove old OS files
    ios_command:
    commands:
  • command: install remove inactive
    prompt: Do you want to remove above files
    answer: y

Still the same problem (timeout). I copied the string direct from the switch. Any idea how to debug this in deep?

Solution: Do not forget the ticks around the ‘y’.

  • name: remove old OS files
    ios_command:
    commands:
  • command: install remove inactive
    prompt: Do you want to remove the above files
    answer: ‘y’
    vars:
    ansible_command_timeout: 180
