Problems with ios_command and prompt '[y/n]'

[Heinz Meier]

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:

---
- hosts: cisco
  tasks:

    - name: Upgrade IOS-XE
      block:

      - name: remove old OS files
        ios_command:
          commands:
            - command: install remove inactive
              prompt: '[y/n]'
              answer: 'y'
        vars:
          ansible_command_timeout: 180

      when: (ansible_net_version != compliant_ios_version) and
            (ansible_net_model is regex("9200"))

Anytime I run this playbook this tasks fails with the timeout. 180 sec should be enough time to delete the files.

I tried to prolong the timeout value, and all combinations of the full text of the question and backslashes in front of the brackets and the forward slash.

Always timeout.

Any ideas?

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
