INSTALLATION AND OPERATION MANUAL

TECH SUPPORT: 1.888.678.9427
Label
Description
Mode
Indicates if 802.1X and MAC-based authentication is globally enabled or disabled on
the switch. If globally disabled, all ports are allowed forwarding of frames.
Reauthentication
Enabled
If checked, 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.
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 Age 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.
Age Period
This setting applies to the following modes, i.e. modes using the Port Security
functionality to secure MAC addresses:
• 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.
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:
• 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.
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.
Port
The port number for which the configuration below applies.
