Table 3-2 Configure and destroy RSA key-pairs 

Operation 

Command 

Generate RSA key-pairs

 

Destroy the RSA key-pairs

 

 

An essential operation underlying a successful SSH login is generating local RSA key-pairs. Before 
performing any other SSH configuration tasks, you must generate a local key-pair by configuring the rsa 
local-key-pair create command. 
It is only necessary for you to execute this command once and you do not have to execute it again after 
rebooting the router. 

Only SSH users can pass the SSH authentication. There are two SSH authentication 

modes: password authentication and RSA authentication.  You can use both at the 

same time. 

When configuring the SSH user, you must set the SSH user’s rights (Administrator, 

Operator or Guest) and    specify the authentication mode.   

Perform the following configuration in system view.

 

Table 3-3 Configure authentication type for an SSH user 

Operation 

Command 

Configure an SSH user 

local-user username service-type ssh { administrator | operator | 
guest } password { simple | cipher } password 

Configure an authentication type for 
an SSH user

 

ssh user username authentication-type 

{ password | RSA | all } 

Remove the authentication type set 
for the specified SSH user

 

undo ssh user username authentication-type

 

By default, login authentication type is not specified for users.  Login requests are 

refused.

 

Perform this task to set a server key-pair updating interval for securing the SSH 

connections to the system.

   

Perform the following configuration in system view.
