Guest VLAN Configuration

Remember, to set a guest 802.1x VLAN, the user must first configure a normal VLAN which can be enabled here for Guest
VLAN status. To view this window, click Security Management > Port Access Entity > RADIUS Server > Guest VLAN,
which will display the following window for the user to configure.
The following fields may be modified to enable the guest 802.1x VLAN:
Parameter Description
VLAN Name Enter the pre-configured VLAN name to create as a guest 802.1x VLAN.
Operation Allows the user to enable or disable ports for the guest 802.1x VLAN, using the Port List stated

Access Authentication Control

The TACACS/XTACACS/TACACS+/RADIUS
TACACS/XTACACS/TACACS+/RADIUS protocols. When a user logs in to the Switch or tries to access the administrator level
privilege, he or she is prompted for a password. If TACACS/XTACACS/TACACS+/RADIUS authentication is enabled on the
Switch, it will contact a TACACS/XTACACS/TACACS+/RADIUS server to verify the user. If the user is verified, he or she is
granted access to the Switch.
There are currently three versions of the TACACS security protocol, each a separate entity. The Switch's software supports the
following versions of TACACS:
•
TACACS (Terminal Access Controller Access Control System) - Provides password checking and authentication, and
notification of user actions for security purposes utilizing via one or more centralized TACACS servers, utilizing the
UDP protocol for packet transmission.
•
Extended TACACS (XTACACS) - An extension of the TACACS protocol with the ability to provide more types of
authentication requests and more types of response codes than TACACS. This protocol also uses UDP to transmit
packets.
•
TACACS+ (Terminal Access Controller Access Control System plus) - Provides detailed access control for
authentication for network devices. TACACS+ is facilitated through Authentication commands via one or more
centralized servers. The TACACS+ protocol encrypts all traffic between the Switch and the TACACS+ daemon, using
the TCP protocol to ensure reliable delivery
