reauthenticated. This is only active if the Reauthentication Enabled checkbox is
checked. Valid values are in the range 1 to 3600 seconds.
Determines the time between retransmission of Request Identity
Valid values are in the range 1 to 255 seconds. This has no effect for MAC-based
ports.
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 a 802.1X-based mode, this is not so
criticial, 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.
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 Un-authorized 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.
