Locked Port Support
Locked Port increases network security by limiting access on a specific port to
users with specific MAC addresses. These addresses are either manually
defined or learned on that port. When a frame is received on a locked port,
and the frame source MAC address is not tied to that port, the protection
mechanism is invoked.
For more information, see Port Security.
RADIUS Client
RADIUS is a client/server-based protocol. A RADIUS server maintains a user
database that contains per-user authentication information, such as user
name, password, and accounting information.
For more information, see RADIUS.
RADIUS Accounting
This feature enables recording device management sessions (Telnet, serial,
and WEB but not SNMP) and/or 802.1x authentication sessions.
The 802.1x Monitor mode enables applying 802.1x functionality to the
switch, with all necessary RADIUS and/or domain servers active, without
actually taking any action that may cause unexpected behavior. In this way,
the user can test the 802.1x setup before actually applying it.
For more information, see RADIUS.
TACACS+
TACACS+ provides centralized security for validation of users accessing the
device. TACACS+ provides a centralized, user management system, while
still retaining consistency with RADIUS and other authentication processes.
For more information, see TACACS+.

Password Management

Password management provides increased network security and improved
password control. Passwords for SSH, Telnet, HTTP, HTTPS, and SNMP
access are assigned security features.
