Command Usage
• The switch uses only RSA Version 1 for SSHv1.5 clients and DSA Version 2 for SSHv2 clients.
• 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.
