On a dlink dgs 1500 switch, we want to restrict access to only a range of IP Addresses. This will allow us to block any outsiders who plug into the network and get an IP address through DHCP. I did the ACL wizard on the switch, but it didn’t work, didn’t block anything. I’m trying to allow network traffic on this switch only to devices with ip address from 10.2.1.0 to 10.2.1.254. How do I do this?
