 Note:
z Selecting the protocol for remote connection as SSH. Usually, a client can use a
variety of remote connection protocols, such as Telnet, Rlogin, and SSH. To
establish an SSH connection, you must select SSH
z Selecting the SSH version. Since the device supports SSH2.0 now, select 2.0 or
lower for the client.
z When an S3100-SI switch acts as the SSH server, select 2.0 for the clients.
z Specifying the private key file. On the server, if public key authentication is enabled
for an SSH user and a public key is set for the user, the private key file
corresponding to the public key must be specified on the client. RSA key pairs and
DSA key pairs are generated by a tool of the client software.
