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 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 switch. If the key is successfully downloaded, the certificate
authentication will be preferred for SSH access to the switch.
