Configuring Port And System; Security - Dell PowerConnect 8024 User Configuration Manual

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 501.
The topics covered in this chapter include:
• IEEE 802.1X
• Port Security (Port-MAC Locking)
• Denial of Service
