Caution:
z For a successful SSH login, you must generate a local RSA key pair first.
z You just need to execute the command once, with no further action required even
after the system is rebooted.
z If you use this command to generate an RSA key provided an old one exits, the
system will prompt you to replace the previous one or not.
z Because multiple devices form a fabric, you need to manually configure the rsa
local-key-pair create command to ensure all devices in the fabric have the same
RSA local key pair.
 Note:
With the rsa local-key-pair create command configured:
z When the switch works in the SSHv1.x compatible mode, if you execute the display
rsa local-key-pair public command, two public keys are displayed. They are
Quidway_Host and Quidway_Server.
z When the switch works in the SSHv2.0 mode, if you execute the display rsa
local-key-pair public command, only one public key is displayed. It is Quidway_
Host.
