– DSA (Version 2) key type.
•
rsa
– RSA (Version 1) key type.
Default Setting

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.
Example
Console#delete public-key admin dsa
Console#
Console#ip ssh crypto host-key generate dsa
Console#
