Configuring Switch-Based Authentication
This chapter describes how to configure switch-based authentication on the IE 3000 switch.
It consists of these sections:
• Preventing Unauthorized Access to Your Switch, page 11-1
• Protecting Access to Privileged EXEC Commands, page 11-2
• Controlling Switch Access with TACACS+, page 11-10
• Controlling Switch Access with RADIUS, page 11-17
• Configuring the Switch for Local Authentication and Authorization, page 11-32
• Configuring the Switch for Secure Shell, page 11-33
• Configuring the Switch for Secure Socket Layer HTTP, page 11-37
• Configuring the Switch for Secure Copy Protocol, page 11-44
Preventing Unauthorized Access to Your Switch
You can prevent unauthorized users from reconfiguring your switch and viewing configuration
information. Typically, you want network administrators to have access to your switch while you restrict
access to users who dial from outside the network through an asynchronous port, connect from outside
the network through a serial port, or connect through a terminal or workstation from within the local
network.
To prevent unauthorized access into your switch, you should configure one or more of these security
features:
• At a minimum, you should configure passwords and privileges at each switch port. These passwords
are locally stored on the switch. When users attempt to access the switch through a port or line, they
must enter the password specified for the port or line before they can access the switch. For more
information, see the
“Protecting Access to Privileged EXEC Commands” section on page 11-2.
• For an additional layer of security, you can also configure username and password pairs, which are
locally stored on the switch. These pairs are assigned to lines or ports and authenticate each user
before that user can access the switch. If you have defined privilege levels, you can also assign a
specific privilege level (with associated rights and privileges) to each username and password pair.
For more information, see the
“Configuring Username and Password Pairs” section on page 11-6.
