“Each of the tools I mentioned before, only have the
ability to manage devices in their realm. Func supports Linux
devices and Cisco LMS supports only Cisco devices.“his tool has one goal. And that is to update your devices with
out deploying any software to your remote devices. All you need is
either telnet or ssh access to your devices and Python2.4 or better
with Pexpect installed. Once you have those 2 requirements
fullfilled, then you are pretty much ready to go.”
