One common solution is a router acting as a terminal server, which uses reverse telnet to remotely console into devices using the console or aux ports however, the total cost of such a project easily can be hundreds of dollars and can be difficult for somebody new to Cisco devices to configure.Ĭisco’s AutoInstall feature provides a convenient automation solution to this issue while minimizing expensive hardware purchases.
The process of plugging in a console cable, erasing the contents of the NVRAM, reloading the device, then initially configuring the device so that you can remotely access it is bearable for a single device, but most networking homelabs have six devices, sometimes more! Modern Cisco devices solve this issue with dedicated management interfaces that retain their configuration even after a write erase command, but these devices tend to be outside the budget of somebody studying for their CCNA or CCNP. Let’s face it: resetting Cisco devices in your homelab to factory defaults is painful.
