5.2.3 SSH
5.2.3.1 Introduction to SSH
SSH (Secure Shell) is a protocol which ensures a secure remote access connection to network
devices. It is based on the reliable TCP/IP protocol. By conducting the mechanism such as key
distribution, authentication and encryption between SSH server and SSH client, a secure connection is
established. The information transferred on this connection is protected from being intercepted and
decrypted. The switch meets the requirements of SSH2.0. It supports SSH2.0 client software such as
SSH Secure Client and putty. Users can run the above software to manage the switch remotely.
The switch presently supports RSA authentication, 3DES cryptography protocol and SSH user
password authentication etc.
