I'd like to know if it is possible, via port-security, to block access to a system based on a MAC address range. In this particular instance, a client of mine wants to prevent patients from bring in gaming consoles (such as PS3 or XBox). However, these patients are allowed to bring in laptops. The prefix for Sony Computer Entertainment is 00041F and Microsoft uses 0050F2 for the XBox so is there a way to say, with port-security, do not allow any MAC beginning with 00:04:1F or 00:50:F2?
I am looking forward to hearing if any one knows a better solution. For example, can the switch auto matically learn the MAC and save them to the MAC table. A ACL applies to a Vlan interface or each switch port to only allow the laptops with the MAC listed on the switch MAC table.
