◆

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.
