ansible - cisco IOS and "reload" command

Question

I would like to send command "reload in " to Cisco IOS, but that specific command needs to be confirmed like below:

#reload in 30
Reload scheduled in 30 minutes by admin on vty0 (192.168.253.15)
Proceed with reload? [confirm]

It semms like ios_command module doesn't handle such case. My configuration:

 tasks:
   - name: do reload in case of "catting off"
     ios_command:
      commands: reload in 30
      commands: y
      provider: "{{ cli }}"

And response from playbook:

How can I handle this?

updated:

If I try to use expect module in YAML file like this:

 name: some tests
  hosts: sw-test
  gather_facts: False
#  connection: local

  tasks:
  - name: do reload in case of "catting off"
    expect:
     command: reload in 30
     responses:
      'Reload scheduled in 30 minutes by admin on vty0 (192.168.253.20)\nProceed with reload? \[confirm\]' : y
     echo: yes

But there is a problem with connection:

UPDATED

I've installed ansible 2.3 and tried as follows:

  tasks:
    - name: do reload in case of "catting off"
      ios_command:
       commands:
        - reload in 30
        - y
       wait_for:
       - result[0] contains "Proceed with reload"
       provider: "{{ cli }}"

But still, I get an error. I think that this is because ios module always wait for a promt as a response. And additionaly confirmation of reload command is without "Enter" after pressing "y" so this could be another problem.

Can anyone have any idea how to resolve that problem in ansible or maby the only way is to use pure python script or write own ansible module?

Answer 1

You can use:

- name: reload device
  ios_command:
    commands:
      - "reload in 1\ny"
    provider: "{{ cli }}"

This will reload the device in 1 minute and the reload prompt gets accepted. It works well for ansible because the default prompt of ios will come back (reload gets triggered in 1 minute).

Regards, Simon

Answer 2

Ansible 2.2 only

You could use something like this:

  - name: send reload command inc confirmation
    ios_command:
      commands: 
        - reload in 30
        - y
      wait_for: 
        - result[0] contains "Proceed with reload" 
      provider: "{{ cli }}"

Not tested but similar to last example for ios_command module.

Take care with Ansible 2.2 though, it's not released yet and new releases of Ansible can have significant regressions.

Ansible 2.0+ includes the expect module but that requires Python on the remote device, so it won't work on IOS or similar devices.

Answer 3

commands parameter of ios_command module expects a YAML formated list of commands. However in the code example provided commands parameter is set multiple times. Try the ios_command task like this:

- name: do reload in case of "catting off"
  ios_command:
    commands:
      - reload in 30
      - y
  provider: "{{ cli }}"

Answer 4

It appears that the simplest method would be to use the 'raw' module to send raw SSH commands to the device.

This avoids having to use expect and having to play around with the ios_command module.

The raw module will run the commands without caring what responses or prompts the device.

Answer 5

Below worked for me with ansible-playbook 2.9.0 and Python 3.7. Please note that, on line with - command , make sure to use double quote " instead of single one ' . And don't forget to put \\n at the end of command.

    - name: Reloading switch using ios_command.
      ios_command:
        commands: 
          - command: "reload\n"
            prompt: 'Proceed with reload? [confirm]'
            answer: "\r"

Answer 6

I have simiar problem. Need to reload cisco device and then getting prompts:

1. save?
2. [confirm]

How to answer that correctly?

• name: Reloading in 1 min if not online cisco.ios.ios_command: commands: - command: reload in 1 prompt: 'System configuration has been modified. Save? [yes/no]:' answer: 'n' answer: 'y'
