Handling multiple device types
In a world where we are not locked into a single vendor, it is important to know how we might handle the different network devices in an infrastructure. We established in the previous chapter that for different infrastructure providers, a similar process was established for each one in terms of getting Ansible to interact with it. This can be a little different with switches as not all command-line switch interfaces are created the same. Some, such as on a Cumulus Networks switch, can make use of straightforward SSH connectivity, meaning that everything we have learned about in this book so far on connecting to an SSH-capable device still applies.
However, other devices, such as F5 BIG-IP, do not use such an interface and therefore require the module to be run from the Ansible host. The configuration parameters must be passed to the module directly as opposed to using simple connection-related host variables such as ansible_user. ...
