Chapter 9 Configuring Switch-Based Authentication
Configuring the Switch for Secure Shell
To disable AAA, use the no aaa new-model global configuration command. To disable authorization,
use the no aaa authorization {network | exec} method1 global configuration command.
Note To secure the switch for HTTP access by using AAA methods, you must configure the switch with the
ip http authentication aaa global configuration command. Configuring AAA authentication does not
secure the switch for HTTP access by using AAA methods.
For more information about the ip http authentication command, see the Cisco IOS Security Command
Reference, Release 12.2.
Configuring the Switch for Secure Shell

install the cryptographic (encrypted) software image on your switch. You must obtain authorization to
use this feature and to download the cryptographic software files from Cisco.com. For more information,
