Secure Shell Commands
The Berkley-standard includes remote access tools originally designed for Unix
systems. Some of these tools have also been implemented for Microsoft Windows
and other environments. These tools, including commands such as
rsh (remote
shell), and rexec (remote execute), are not secure from hostile attacks.
The Secure Shell (SSH) includes server/client applications intended as a secure
replacement for the older Berkley remote access tools. SSH provides remote
management access via encrypted paths between the switch and SSH-enabled
management station clients. The commands described in this section show how to
configure the SSH server. However, you also need to install a SSH client on the
management station when using this protocol to configure the switch. When the
client contacts the switch via the SSH protocol, the switch generates a public-key
that the client uses along with a local user name and password for access
authentication.
Note: The switch supports only SSH Version 1.5.
ip ssh server
Use this command to enable the Secure Shell (SSH) server on this switch. Use the
no form to disable this service.
