Global Config - TP-Link T2600G-28TS User Manual

3. Quiet-period timer (Quiet Period): This timer sets the quiet-period. When a supplicant
system fails to pass the authentication, the switch quiets for the specified period before it
processes another authentication request re-initiated by the supplicant system.
Guest VLAN

Guest VLAN function enables the supplicants that do not pass the authentication to access the
specific network resource.
By default, all the ports connected to the supplicants belong to a VLAN, i.e. Guest VLAN. Users
belonging to the Guest VLAN can access the resources of the Guest VLAN without being
authenticated. But they need to be authenticated before accessing external resources. After
passing the authentication, the ports will be removed from the Guest VLAN and be allowed to
access the other resources.
With the Guest VLAN function enabled, users can access the Guest VLAN to install 802.1X client
program or upgrade their 802.1x clients without being authenticated. If there is no supplicant past
the authentication on the port in a certain time, the switch will add the port to the Guest VLAN.
With 802.1X function enabled and Guest VLAN configured, after the maximum number retries
have been made to send the EAP-Request/Identity packets and there are still ports that have not
sent any response back, the switch will then add these ports into the Guest VLAN according to
their link types. Only when the corresponding user passes the 802.1X authentication, the port will
be removed from the Guest VLAN and added to the specified VLAN. In addition, the port will back
to the Guest VLAN when its connected user logs off.
The 802.1X function is implemented on the Global Config and Port Config pages.
