I want to use my raspberry pi as a way of configuring my switch.
My switch is a Netgear brand switch.
The issue I have is that the network itself is not connected to the internet and the RPI is connected to the switch only via an Ethernet cable.
Is this possible? Or should I look for a different approach.
I don’t know your switch but it must have an interface for manageing it, sometimes with an extra serial connection, but mostly with a connection through any of its ethernet ports. You should always find a text console on the management connection but most modern switches also provide a http interface that you can use with an internet browser. With the RasPi connected to the switch you should be able to use the text console of the switch with telnet, or ssh. To use the http interface just put the initial ip address of the switch into the internet browser address line and connect. Details about these connections, e.g. initial ip address, telnet and ssh password etc. you should find in the manual of the switch.
