Command Usage

•This command stores the host key pair in memory (i.e., RAM). Use the ip ssh save host-keycommand 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.
