Command Descriptions

outlined below.

This option is only available for EAPOL-based modes, i.e.:

• Port-based 802.1X

• Single 802.1X

• Multi 802.1X

For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN

Membership and VLAN Port" pages. These pages show which modules have

(temporarily) overridden the current Port VLAN configuration.

Guest VLAN Operation:

When a Guest VLAN enabled port's link comes up, the switch starts transmitting

EAPOL Request Identity frames. If the number of transmissions of such frames

exceeds Max. Reauth. Count and no EAPOL frames have been received in the

meanwhile, the switch considers entering the Guest VLAN. The interval between

transmission of EAPOL Request Identity frames is configured with EAPOL Timeout. If

Allow Guest VLAN if EAPOL Seen is enabled, the port will now be placed in the Guest

VLAN. If disabled, the switch will first check its history to see if an EAPOL frame has

previously been received on the port (this history is cleared if the port link goes down

or the port's Admin State is changed), and if not, the port will be placed in the Guest

VLAN. Otherwise it will not move to the Guest VLAN, but continue transmitting

EAPOL Request Identity frames at the rate given by EAPOL Timeout.

Once in the Guest VLAN, the port is considered authenticated, and all attached clients

on the port are allowed access on this VLAN. The switch will not transmit an EAPOL

Success frame when entering the Guest VLAN.

While in the Guest VLAN, the switch monitors the link for EAPOL frames, and if one

such frame is received, the switch immediately takes the port out of the Guest VLAN

and starts authenticating the supplicant according to the port mode. If an EAPOL

frame is received, the port will never be able to go back into the Guest VLAN if the

"Allow Guest VLAN if EAPOL Seen" is disabled.

Port State

The current state of the port. It can undertake one of the following values:

Globally Disabled: NAS is globally disabled.

Link Down: NAS is globally enabled, but there is no link on the port.

Authorized: The port is in Force Authorized or a single-supplicant mode and the

supplicant is authorized.

Unauthorized: The port is in Force Unauthorized or a single-supplicant mode and the

supplicant is not successfully authorized by the RADIUS server.

X Auth/Y Unauth: The port is in a multi-supplicant mode. Currently X clients are

authorized and Y are unauthorized.
