For example, if you have a play to upgrading router images, you want to include a step to make sure the new router image is on the device before you move on to the next play of rebooting the router.
In this section, we will discuss the when clause, which is supported for all modules, as well as unique conditional states that are supported in Ansible networking command modules. Some of the conditions are as follows:
- Equal to (
eq) - Not equal to (
neq) - Greater than (
gt) - Greater than or equal to (
ge) - Less than (
lt) - Less than or equal to (
