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.
To secure the switch for HTTP access by using AAA methods, you must configure the switch with the
Note
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 12.4.

For SSH configuration examples, see the "SSH Configuration Examples" section in the "Configuring
Secure Shell" section in the "Other Security Features" chapter of the Cisco IOS Security Configuration
Guide, Cisco IOS Release 12.4.
SSH functions the same in IPv6 as in IPv4. For IPv6, SSH supports IPv6 addresses and enables secure,
encrypted connections with remote IPv6 nodes over an IPv6 transport.

Understanding SSH
SSH is a protocol that provides a secure, remote connection to a device. SSH provides more security for
remote connections than Telnet does by providing strong encryption when a device is authenticated. This
software release supports SSH Version 1 (SSHv1) and SSH Version 2 (SSHv2).
This section consists of these topics:

SSH Servers, Integrated Clients, and Supported Versions
The SSH feature has an SSH server and an SSH integrated client, which are applications that run on the
switch. You can use an SSH client to connect to a switch running the SSH server. The SSH server works
with the SSH client supported in this release and with non-Cisco SSH clients. The SSH client also works
with the SSH server supported in this release and with non-Cisco SSH servers.
The switch supports an SSHv1 or an SSHv2 server.
