Recently a student assigned a static IP to their personal device connected to our network. The IP they chose was the default gateway IP of the vlan. This caused alot of problems as there was now an IP conflict.
I was wondering what kind of configuration I could put on my extreme 440/450s on the edge to prevent this. On reddit someone said on cisco this would be called " ip arp inspection and ip source guard". I looked on Gtac and saw something like this. If this is a solution, could I see an sample configuration to stop an edge port from using a static IP of say 10.18.96.1?
