Using Passwords and TACACS+ To Protect Against Unauthorized Access
Configuring Username and Password Security
Using Passwords and
TACACS+
• If incorrect passwords are entered, the TACACS+ server denies
access to the switch.
• If TACACS+ is not configured or the TACACS+ server is not accessi-
ble, the switch uses local user-name/password protection (step 1,
below).
3. If the switch has an Authorized IP Managers list (see chapter 10) , the
management station must be included in this list.
• If the station is not authorized, the switch denies access.
• If the switch has no Authorized IP Manager list, then the switch uses
TACACS+ authentication, if configured and available (step 2, below).
The preceding information outlines general access security. To understand the
options offered by each security feature, refer to the appropriate sections in
this chapter and chapter 10.
