Cisco Switch Configuration for 2940, 2950, 2960, etc.

by KX5DX

I decided to go with a Cisco switch even though I have a Netgear 108E already. After trying to do a custom setup, on the Netgear I found the GUI to be clunky and cumbersome as it can get. So went ahead and configured my station's Cisco 2950 24 port for my AREDN setup(work in progress). I figured that there might be a lot of people that will not try a Cisco switch due to the CLI. So here is a "copy and paste" configuration to ease the pain.

There are 2940s on ebay going for $25, and I was just able to buy an 8 port 2960 for $40 shipped. I found the 2940 to be outdated for my taste but it still works for AREDN.

This configuration is for a 3 band hub site with one LAN port for each device and internet access to all 3 devices. It should work for any "fixed" interface Cisco switch, 2940, 2950, 2960, etc. If using a gigabit switch, or different port numbers on a 24 or 48 port switch, rename the interfaces accordingly.
