Port security is enabled on most ports, meaning that users are not permitted to attach a switch to the network and must pay for new connections for all devices. While the $20/month fee for gigabit connectivity is generally thought to be reasonable, many department networks require them to evade this restriction through the use of NAT routing, ARP proxies, and/or NDP proxies. For most public portals, MAC address registration is often required, although some department ports are known to not carry this restriction.
