Chapter 18 Port Authentication Table 43 Advanced Application > Port Authentication > 802.1x (continued) LABEL DESCRIPTION Reauth Specify if a subscriber has to periodically re-enter his or her username and password to stay connected to the port. Reauth-period Specify the length of time required to pass before a client has to re-enter his or her username and password to stay connected to the port. Quiet-period Specify the number of seconds the port remains in the HELD state and rejects further authentication requests from the connected client after a failed authentication exchange. Tx-period Specify the number of seconds the Switch waits for client's response before re-sending an identity request to the client. Supp-Timeout Specify the number of seconds the Switch waits for client's response to a challenge request before sending another request. Apply Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. Cancel Click Cancel to begin configuring this screen afresh. 18.2.2 Guest VLAN When 802.1x port authentication is enabled on the Switch and its ports, clients that do not have the correct credentials are blocked from using the port(s). You can configure your Switch to have one VLAN that acts as a guest VLAN. If you enable the guest VLAN (102 in the example) on a port (2 in the example), the user (A in the example) that is not IEEE 802.1x capable or fails to enter the correct username and password can still access the port, but traffic from the user is forwarded to the guest VLAN. That is, unauthenticated users can have access to limited network resources in the same guest VLAN, such as the Internet. The rights granted to the Guest VLAN depends on how the network administrator configures switches or routers with the guest network feature.
