Command Line Interface
4-38

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.
