Abstract
A method of managing network traffic. The method includes initializing a database in communication with a network device. The database includes a number of MAC address entries and a network flooding entry associated with each of the number of MAC address entries. Each of the number of MAC address entries is associated with a station known to the network. The method also includes receiving network traffic at the network device. The network traffic is associated with a MAC source address. The method further includes determining whether the MAC source address is included in the database, automatically learning a location associated with the MAC source address, and forwarding the network traffic over the network if the MAC source address is included in the database. Additionally, the method includes dropping or trapping the network traffic if the MAC source address is not included in the database. Dropping the network traffic is performed without interaction with a CPU.
