Table 275: Port Access Control—Port Configuration Fields
Field
Description
Administrative Mode
Select
Enable
or
Disable
802.1x mode on the switch. The default is Disable. This
feature permits port-based authentication on the switch.
VLAN Assignment Mode
If enabled, when a supplicant is authenticated by a authentication server, the
port that the supplicant is connected to is placed in a particular VLAN specified
by the
server. VLAN Assignment mode controls if the switch is allowed
to place a port in a RADIUS-assigned VLAN. A port’s VLAN assignment is
determined by the first supplicant that is authenticated on the port.
Dynamic VLAN Creation Mode Select
Enable
to allow the switch to dynamically create a RADIUS-assigned
VLAN if it does not already exist in the VLAN database.
Monitor Mode
The administrative mode of the Monitor Mode feature on the device. Monitor
mode is a special mode that can be enabled in conjunction with port-based
access control. Monitor mode provides a way for network administrators to
identify possible issues with the port-based access control configuration on the
device without affecting the network access to the users of the device. It allows
network access even in cases where there is a failure to authenticate, but it logs
the results of the authentication process for diagnostic purposes. If the device
fails to authenticate a client for any reason (for example, RADIUS access reject
from the RADIUS server, RADIUS timeout, or the client itself is 802.1X unaware),
the client is authenticated and is undisturbed by the failure condition(s). The
reasons for failure are logged and buffered into the local logging database for
tracking purposes.
EAPOL Flood Mode
The administrative mode of the Extensible Authentication Protocol (EAP) over
LAN (EAPOL) flood support on the device. EAPOL Flood Mode can be enabled
when Admin Mode and Monitor Mode are disabled.
If you change any of the parameters, click
Submit
to apply the changes to the system. If you want the
switch to retain the new values across a power cycle, you must save the configuration.
