Chapter 5: Configuring the Switch through the Web Utility
Security
24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet
802.1xPort Conf.
When 802.1X is enabled, you need to configure the parameters for the authentication process that runs between
the client and the switch (that is, authenticator), as well as the client identity lookup process that runs between
the switch and authentication server. These parameters are described in this section.
Modify the parameters required using the drop-down menus and textfields provided, and click Submit.
Max-Req. Sets the maximum number of times the switch port will retransmit an EAP request packet to the client
before it times out the authentication session. (Range: 1-10; Default 2)
Quiet Period. Sets the time that a switch port waits after the Max Request Count has been exceeded before
attempting to acquire a new client. (Range: 1-65535 seconds; Default: 60 seconds)
Re-authen Period. Sets the time period after which a connected client must be re-authenticated. (Range: 1-
65535 seconds; Default: 3600 seconds)
TX Period. Sets the time period during an authentication session that the switch waits before re-transmitting an
EAP packet. (Range: 1-65535; Default: 30 seconds)
Supplicant. This Indicates the MAC address of a connected client.
Radius Server
Remote Authentication Dial-in User Service (RADIUS) and Terminal Access Controller Access Control System Plus
(TACACS+) are logon authentication protocols that use software running on a central server to control access to
RADIUS-aware or TACACS-aware devices on the network. An authentication server contains a database of
multiple user name/password pairs with associated privilege levels for each user that requires management
access.
RADIUS and TACACS+ logon authentication assign a specific privilege level for each user name/password pair.
The user name, password, and privilege level must be configured on the authentication server.
To configure local or remote authentication preferences, specify the authentication sequence (that is, one to three
methods), fill in the parameters for RADIUS or TACACS+ authentication if selected.
Secret Text String. Encryption key used to authenticate logon access for client. Do not use blank spaces in the
string. (Maximum length: 20 characters)
