Switch Features 61
Password-Protected Management Access
Access to the Web, CLI, and SNMP management interfaces is password
protected, and there are no default users on the system.
For information about configuring local user accounts, see "Controlling
Management Access" on page 171.
Strong Password Enforcement
The Strong Password feature enforces a baseline password strength for all
locally administered users. Password strength is a measure of the effectiveness
of a password in resisting guessing and brute-force attacks. The strength of a
password is a function of length, complexity and randomness. Using strong
passwords lowers overall risk of a security breach.
For information about configuring password settings, see "Controlling
Management Access" on page 171.
TACACS+ Client
The switch has a TACACS+ client. TACACS+ provides centralized security
for validation of users accessing the switch. TACACS+ provides a centralized
user management system while still retaining consistency with RADIUS and
other authentication processes.
For information about configuring TACACS+ client settings, see
"Controlling Management Access" on page 171.
RADIUS Support
The switch has a Remote Authentication Dial In User Service (RADIUS)
client and can support up to 32 named authentication and accounting
RADIUS servers. The switch also supports RADIUS Attribute 4, which is the
configuration of a NAS-IP address. You can also configure the switch to
accept RADIUS-assigned VLANs.
For information about configuring RADIUS client settings, see "Controlling
Management Access" on page 171.
