Command Usage
• This command stores the host key pair in memory (i.e., RAM). Use the
ip ssh save host-key command to save the host key pair to flash
memory.
• Some SSH client programs automatically add the public key to the
known hosts file as part of the configuration process. Otherwise, you
must manually create a known hosts file and place the host public key
in it.
• The SSH server uses this host key to negotiate a session key and
encryption method with the client trying to connect to it.
