Description
Factory Default
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 determines 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.
Unclicked
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; 4095].
1
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. Valid values are in the range [1; 255].
2
Allow Guest VLAN if
EAPOL Seen
The switch remembers if an EAPOL frame has been received on the port
for the life-time of the port. Once the switch considers whether to enter the
Guest VLAN, it will first check if this option is enabled or disabled. If
disabled (unchecked; default), the switch will only enter the Guest VLAN
if an EAPOL frame has not been received on the port for the life-time of
the port. If enabled (checked), the switch will consider entering the Guest
VLAN even if an EAPOL frame has been received on the port for the life-
time of the port. The value can only be changed if the Guest VLAN option
is globally enabled.
Unclicked
Port Configuration
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 comes 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 comes up, and any client on the port will be disallowed network
access.
Port-based 802.1X
In the 802.1X-world, 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. EAPOL frames encapsulate
EAP PDUs (RFC3748). Frames sent between the switch and the RADIUS
server are RADIUS packets. RADIUS packets also encapsulate EAP
PDUs together with other attributes like the switch's IP address, name, and
the supplicant's port number on the switch. EAP is very flexible, in that it
allows for different authentication methods, like MD5-Challenge, PEAP,
