The page includes the following fields:
System Configuration
Object Description
Indicates
if NAS is globally enabled or disabled on the switch. If globally disabled,
all ports are allowed forwarding of frames.
ï‚· Mode
If checked, successfull
y authenticated supplicants/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 or if a supplicant is no longer attached.
ï‚· Reauthentication
Enabled
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.
