Security Configuration
This chapter describes the Security Configuration set of commands and how to use them.
Overview of Security Methods
The following security methods are available for controlling which users are allowed to access,
monitor, and manage the switch.
• Login user accounts and passwords – used to log in to the CLI via a Telnet connection or local
COM port connection. For details, refer to “ Setting User Accounts and Passwords ” on
page 3 ‐ 1.
• Host Access Control Authentication (HACA) – authenticates user access of Telnet
management, console local management and WebView via a central RADIUS Client/Server
application. When RADIUS is enabled, this essentially overrides login user accounts. When
HACA is active per a valid RADIUS configuration, the user names and passwords used to
access the switch via Telnet, SSH, WebView, and COM ports will be validated against the
configured RADIUS server. Only in the case of a RADIUS timeout will those credentials be
compared against credentials locally configured on the switch. For details, refer to
“ Configuring RADIUS ” on page 18 ‐ 3.
• SNMP user or community names – allows access to the SecureStack C2 switch via a network
SNMP management application. To access the switch, you must enter an SNMP user or
community name string. The level of management access is dependent on the associated
access policy. For details, refer to Chapter 6 .
• 802.1X Port Based Network Access Control using EAPOL (Extensible Authentication
Protocol) – provides a mechanism via a RADIUS server for administrators to securely
