2.2.2 SSH
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.
