Table 4-78: Network Access Server Configuration Parameters
System Configuration
Mode Indicates if NAS is globally enabled or disabled on the switch If globally
disabled, all ports are allowed forwarding of 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.
When the NAS module uses the Port Security module to secure MAC
addresses, the Port Security module needs to check for activity on the
MAC address in question at regular intervals and free resources if no
activity is seen within a given period of time. This parameter controls
exactly this period and can be set to a number between 10 and
1000000 seconds.
If reauthentication is enabled and the port is in an 802.1X-based mode,
this is not so critical, since supplicants that are no longer attached to
the port will get removed upon the next reauthentication, which will fail.
But if reauthentication is not enabled, the only way to free resources is
by aging the entries.
For ports in MAC-based Auth. mode, reauthentication doesn't cause
direct communication between the switch and the client, so this will not
detect whether the client is still attached or not, and the only way to
free any resources is to age the entry.
