4.2.4.3 SSH Config
As stipulated by IFTF (Internet Engineering Task Force), SSH (Secure Shell) is a security protocol established on application
and transport layers. SSH-encrypted-connection is similar to a Telnet connection, but essentially the old Telnet remote
management method is not safe, because the password and data transmitted with plain text can be easily intercepted. SSH can
provide information security and powerful authentication when you log on to the Managed Switch remotely through an insecure
network environment. It can encrypt all the transmission data and prevent the information in a remote management being
leaked. Comprising server and client, SSH has two versions, V1 and V2, which are not compatible with each other. In the
communication, SSH server and client can auto-negotiate the SSH version and the encryption algorithm. After getting a
successful negotiation, the client sends authentication request to the server for login, and then the two can communicate with
each other after successful authentication.
This Managed Switch supports SSH server and you can log on to the switch via SSH connection using SSH client software.
SSH key can be downloaded into the Managed Switch. If the key is successfully downloaded, the certificate authentication will
be preferred for SSH access to the Managed Switch.The screen in Figure 4-2-19 appears.
