Parameter
None
Description
Use the rsa local-key-pair create command to generate RSA key pairs, including the
host key pair and the server key pair.
z The name of the host key pair is in the format of switch name plus _Host, for
example, 3Com_Host.
z The name of the server key pair is in the format of switch name plus _Server, for
example, 3Com_Server.
Note:
z Server key pair (3Com_Server) is not used in SSHv2.0; therefore, when the rsa
local-key-pair create command is executed, the system only prompts you the host
RSA key pair (3Com_Host) is generated, and does not inform you the information
about the server key pair even if the server key pair is generated in the background
for the purpose of SSHv1.x compatibility. You can use the display rsa
local-key-pair public command to display the generated key pairs.
After you configure the rsa local-key-pair create command, the system prompts you
to define the key length.
z In SSHv1.x, the key length is in the range of 512 to 2,048 (bits).
z In SSHv2.0, the key length is in the range of 768 to 2048 (bits).
z If you use this command to generate an RSA key provided an old one exists, the
system will prompt you to replace the previous one or not.
