This section describes how to configure the Secure Shell (SSH) feature. To use this feature, you must
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,
see the release notes for this release.

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, page 7-37
• Limitations, page 7-38
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.
