Items Description
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:
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.
Hold Time 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.
If a client is denied access - either because the RADIUS server denies
the client access or because the RADIUS server request times out
(according to the timeout specified on the
"Configuration→Security→AAA" page) - the client is put on hold in
the Unauthorized state. The hold timer does not count during an on-
going authentication.
In MAC-based Auth. mode, the switch will ignore new frames coming
from the client during the hold time.
The Hold Time can be set to a number between 10 and 1000000
seconds.
RADIUS-Assigned
QoS Enabled RADIUS-assigned QoS provides a means to centrally control the traffic
class to which traffic coming from a successfully authenticated
supplicant is assigned on the switch. The RADIUS server must be
configured to transmit special RADIUS attributes to take advantage of
this feature (see RADIUS-Assigned QoS Enabled below for a detailed
description).
The "RADIUS-Assigned QoS Enabled" checkbox provides a quick way
to globally enable/disable RADIUS-server assigned QoS Class
functionality. When checked, the individual ports' ditto setting
determine whether RADIUS-assigned QoS Class is enabled on that
port. When unchecked, RADIUS-server assigned QoS Class is disabled
on all ports
RADIUS-Assigned
VLAN Enabled RADIUS-assigned VLAN provides a means to centrally control the
VLAN on which a successfully authenticated supplicant is placed on
the switch. Incoming traffic will be classified to and switched on the
RADIUS-assigned VLAN. The RADIUS server must be configured to
transmit special RADIUS attributes to take advantage of this feature
(see RADIUS-Assigned VLAN Enabled below for a detailed
description).
The "RADIUS-Assigned VLAN Enabled" checkbox provides a quick way
to globally enable/disable RADIUS-server assigned VLAN
functionality. When checked, the individual ports' ditto setting
determine whether RADIUS-assigned VLAN is enabled on that port.
