3 Authentication and Data Transmission
After the identification is verified and data encryption activated, a secure tunnel is
established between the client and the server. The client then sends its authentication
information (user name and password) to the server to log in to the server.
22.7 SSH Implementation on the Switch
Your switch supports SSH version 2 using RSA authentication and three encryption methods
(DES, 3DES and Blowfish). The SSH server is implemented on the switch for remote
management and file transfer on port 22. Only one SSH connection is allowed at a time.
22.7.1 Requirements for Using SSH
You must install an SSH client program on a client computer (Windows or Linux operating
system) that is used to connect to the switch over SSH.
22.7.2 SSH Login Example
You can use an SSH client program to access the switch. The following figure shows an
example using a text-based SSH client program. Refer to the documentation that comes with
your SSH program for information on using it.
