Port Access Control
Authenticator Options
The fields in this section can be changed only when the selected port is configured as an authenticator port (that is, the PAE
Capabilities field is set to Authenticator.
Control Mode
The port-based access control mode on the port, which is one of the following:
Auto – The port is unauthorized until a successful authentication exchange has taken
place.
Force Unauthorized – The port ignores supplicant authentication attempts and does not
provide authentication services to the client.
Force Authorized – The port sends and receives normal traffic without client port-based
authentication.
MAC-Based – This mode allows multiple supplicants connected to the same port to each
authenticate individually. Each host connected to the port must authenticate separately
in order to gain access to the network. The hosts are distinguished by their MAC
addresses.
Quiet Period
The number of seconds that the port remains in the quiet state following a failed
authentication exchange.
Transmit Period
The value, in seconds, of the timer used by the authenticator state machine on the port to
determine when to send an EAPOL EAP Request/Identity frame to the supplicant.
Guest VLAN ID
The VLAN ID for the guest VLAN. The guest VLAN allows the port to provide a distinguished
service to unauthenticated users. This feature provides a mechanism to allow users access
to hosts on the guest VLAN. When this field is 0, the guest VLAN facility is disabled.
Guest VLAN Period
The value, in seconds, of the timer used for guest VLAN authentication.
Unauthenticated VLAN ID
The VLAN ID of the unauthenticated VLAN. Hosts that fail the authentication might be denied
access to the network or placed on a VLAN created for unauthenticated clients. This VLAN
might be configured with limited network access. To set the unauthenticated VLAN ID, click
the
Edit
icon associated with the field and specify the ID value in the available field. To reset
the unauthenticated VLAN ID to the default value, click the Reset icon associated with the
field and confirm the action.
Supplicant Timeout
The amount of time that the port waits for a response before retransmitting an EAP request
frame to the client.
Server Timeout
The amount of time the port waits for a response from the authentication server.
MAB Mode
The MAC-based Authentication Bypass (MAB) mode on the port, which can be enabled or
disabled.
Maximum Requests
The maximum number of times that the port sends an EAP request frame (assuming that no
response is received) to the client before restarting the authentication process.
Re-Authentication Period
The amount of time that clients can be connected to the port without being reauthenticated.
If this field is disabled, connected clients are not forced to reauthenticate periodically. To
change the value, click the
Edit
icon associated with the field and specify a value in the
available field. To reset the reauthentication period to the default value, click the Reset icon
associated with the field and confirm the action.
