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.
 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 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.
When unchecked, RADIUS-server assigned VLAN is disabled on all ports.
 Guest VLAN Enabled :
A Guest VLAN is a special VLAN - typically with limited network access - on which
802.1X-unaware clients are placed after a network administrator-defined timeout. The
switch follows a set of rules for entering and leaving the Guest VLAN as listed below.
The "Guest VLAN Enabled" checkbox provides a quick way to globally enable/disable
Guest VLAN functionality. When checked, the individual ports' ditto setting determines
whether the port can be moved into Guest VLAN. When unchecked, the ability to move to
the Guest VLAN is disabled on all ports.
 Guest VLAN ID :
This is the value that a port's Port VLAN ID is set to if a port is moved into the Guest VLAN.
It is only changeable if the Guest VLAN option is globally enabled.
