Practical Network Automation - Second Edition

Section 2 – defining what to execute (define the task)

This is the critical section where we use a specific module of Ansible (ios_command) to define what to execute on the network devices:

tasks:  - name: run ping for the host      ios_command:        commands: ping 8.8.8.8 repeat 1      register: trace_result    - name: Debug registered variables      debug: var=trace_result

We define a ping 8.8.8.8 repeat 1 command and capture the result in a variable called trace_result, which is defined using the register keyword.

Finally, using the debug keyword, the output captured in the trace_result variable is displayed onscreen.

For further information about ios_module, you can refer to Ansible's online documentation at https://docs.ansible.com/ansible/2.5/modules/ios_command_module.html ...
