Unable to run sh run playbook on cisco_csr

chinmasw · February 19, 2024, 10:36am

I can run other sh commands like sh version, sh ip int brief but the sh run doesn’t work on the cisco CSR. What I am missing here?

@chinmasw Hello.

The user who login to devices does not have privilege permission.

Maybe you can execute show version not show running-config.

You should use a privilege user or privilege escalation to execute show running-config.

@chinmasw

As per the error message can not use content with a dir as dest, you should specify file path to dest option of copy module.

akira6592 · February 19, 2024, 1:13pm

@chinmasw

For example, how about the following.

- name: Save output to ~/ansible/backups
  copy:
    content: "{{ config.stdout[0] }}"
    dest: "~/ansible/backups/{{ hostvars.cisco_csr.DTG }}/show_running-config.txt"

In this case the dest option needs a file path.

Your Awesome it works. As a extension to the playbook, I am adding some of the show commands output. l guess I need to use some template like j2 for storing multiple sh commands output as the .txt you can only save 1 show command output. Is there a way out of not using j2?

akira6592 · February 20, 2024, 12:16pm

@chinmasw

There are two ways to store the results of multiple show commands.

Store one result to per file.
like show_running-config.txt, show_version.txt and so on.
Store multiple results to one file.

Which way do you like?

chinmasw · February 21, 2024, 3:58am

Option 2 storing in 1 file with multiple results.

akira6592 · February 21, 2024, 1:06pm

@chinmasw

There are several ways to do it… How about this one?

  tasks:
    - name: show run on device
      ios_command:
        commands:
          - show running-config
          - show version
      register: config

    - name: Save output to ~/ansible/backups
      blockinfile:
        path: "~/ansible/backups/{{ hostvars.cisco_csr.DTG }}/show_results.txt"
        block: "{{ item }}"
        marker: "======================================" # separator
        create: true
      loop: "{{ config.stdout }}"
      loop_control:
        label: " " # suppressing log output

Works perfectly. Thank you for your help
