Description
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 does not cause direct
communications 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 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
Admin State
If NAS is globally enabled, this selection controls the port’s authentication mode.
The following modes are available:
Force Authorized
In this mode, the switch will send one EAPOL Success frame when the port
link is up, and any client on the port will be allowed network access without
authentication.
Force Unauthorized
In this mode, the switch will send one EAPOL Failure frame when the port link is
up, and any client on the port will be disallowed network access.
Port-based 802.1X
In an 802.1X network environment, the user is called the supplicant, the switch
is the authenticator, and the RADIUS server is the authentication server. The
authenticator acts as the man-in-the-middle, forwarding requests and responses
between the supplicant and the authentication server. Frames sent between the
supplicant and the switch are special 802.1X frames, known as EAPOL (EAP Over
LANs) frames which encapsulate EAP PDUs (RFC3748).
