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:

This field shows one of the following port states:
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:

Restart:

Click one of the following buttons to reauthenticate or reinitialize the post:
Reauthenticate: Schedules a reauthentication whenever the quiet-period of the port runs out (EAPOL-based authentication). For MAC-based

authentication, reauthentication will be attempted immediately. This button only has effect for successfully authenticated clients on the port
and will not cause the clients to get temporarily unauthorized.
Reinitialize: Forces a reinitialization of the clients on the port and thereby a reauthentication immediately. The clients will transfer to the unau-

thorized state while the reauthentication is in progress.
These buttons are only enabled when authentication is globally enabled and the port's Admin State is in an EAPOL-based or MAC-based mode.
Clicking these buttons will not cause settings changed on the page to take effect.
MGS3600-24F/XGS3600-26F/XGS3600-28F
NAS is globally disabled.
The port is in a multi-supplicant mode. Currently X clients are authorized and Y are unauthorized.
