Configuration Steps

Step 1: Create VLANs, and add ports to the required VLANs.(Omitted)

Step 2: Configures IP addresses for the ports. (Omitted)

Step 3: Configure a local user and the related properties.

#Configure the user name and password of Device2.

Device2#configure terminal
Device2(config)#local-user admin1 class manager
Device2(config-user-manager-admin1)#service-type ssh
Device2(config-user-manager-admin1)#password 0 admin1
Device2(config-user-manager-admin1)#exit

Step 4: Enable the SSH server function of Device2.

Device2(config)#ip ssh server

Step 5: Set the login authentication mode to local authentication.

Device2(config)#line vty 0 15
Device2(config-line)#login aaa
Device2(config-line)#exit

Step 6: On Device1, log in to Device2 through SSH.

#Configure Device1 to log in to Device2 through SSH.

Device1#ssh  version 2 2.0.0.1 22 admin1 auth-method 1 admin1
The authenticity of host '2.0.0.1' can't be established
RSA key fingerprint is 7b:ed:cc:81:cf:12:36:6f:f7:ff:29:15:63:75:64:10.
Are you sure you want to continue connecting (yes/no)? yes
Device2>

Step 7: Check the result.

If the login succeeds, the shell screen of Device2 is displayed.

note


  • If the "Connection closed by foreign host" message is displayed, it indicates that the SSH service of the peer end is disabled, or the inputted user name or password is incorrect.
  • The SSH server can be configured not to use authentication. If the SSH server does not use authentication, when a client logs in, a user can use any character string as the user name and password.
