20 Configuring Port and System Security This chapter describes how to configure port-based security features, which control access to the network through the switch ports, and the denial of service (DoS) feature. Port-based security includes IEEE 802.1X authentication and port MAC locking. • IEEE 802.1X provides an authentication mechanism to devices connected to the switch. Network access is permitted only to authorized devices (clients). • Port MAC locking is used to enable security on a per-port basis. When a port is locked, only packets with allowable source MAC addresses can be forwarded. All other packets are discarded. Port-MAC locking allows a configurable limit to the number of source MAC addresses that can be learned on a port. NOTE: Port-based security can also be accomplished by using Access Control Lists (ACLs). For information about configuring ACLs, see "Configuring Access Control Lists" on page 513. The topics covered in this chapter include: • IEEE 802.1X • Port Security (Port-MAC Locking) • Denial of Service Configuring Port and System Security 469
