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. 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.
Valid values are in the range [1; 4094].
Max. Reauth. Count:
The number of times the switch transmits an EAPOL Request Identity frame without response before considering entering
the Guest VLAN is adjusted with this setting. The value can only be changed if the Guest VLAN option is globally enabled.
