CHAPTER 10: SECURITY
FIGURE 10-5. NETWORK ACCESS SERVER CONFIGURATION
PARAMETER DESCRIPTION
System Configuration
Mode: on or off. Indicates if IEEE 802.1X is globally enabled or disabled on the switch. If globally disabled, all ports are allowed to
forward frames.
Reauthentication Enabled: If checked, successfully authenticated supplicants/clients are reauthenticated after the interval specified
by the Reauthentication Period. Reauthentication for 802.1X-enabled ports can be used to detect if a new device is plugged into a
switch port or if a supplicant is no longer attached.
For MAC-based ports, reauthentication is only useful if the RADIUS server configuration has changed. It does not involve
communication between the switch and the client, and therefore doesn’t imply that a client is still present on a port (see Aging
Period below).
Reauthentication Period: Determines the period, in seconds, after which a connected client must be reauthenticated. This is only
active if the Reauthentication Enabled checkbox is checked. Valid values are in the range 1 to 3600 seconds.
EAPOL Timeout: Determines the time for retransmission of Request Identity EAPOL frames.
Valid values are in the range 1 to 65535 seconds. This has no effect for MAC-based ports.
Aging Period: This setting applies to the following modes, i.e. modes using the Port Security functionality to secure MAC addresses:
• Single 802.1X
• Multi 802.1X
• MAC-Based Auth.
