Configuring The Ssh Client; Ssh Client Configuration Task List; Configuring An Ssh Client That Runs Ssh Client Software - H3C S5100-SI Operation Manual

With the filename argument specified, you can export the RSA or DSA host public key to a file so
that you can configure the key at a remote end by importing the file. If the filename argument is not
specified, this command displays the host public key information on the screen in a specified
format.
The RSA host public key format can be SSH1, SSH2 and OpenSSH, while the DSA host public key
format can be SSH2 and OpenSSH. DSA does not support the format of SSH1.

The configurations required on the SSH client are related to the authentication mode that the SSH
