Command Descriptions

• 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 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.
