Under Protocol options, select 2 from Preferred SSH protocol version. Then, click Open. If the
connection is normal, you will be prompted to enter the user name hello and the password. Once
authentication succeeds, you will log in to the server. The level of commands that you can access after
login is authorized by the CAMS server. You can specify the level by setting the EXEC Privilege Level
argument in the Add Account window shown in
Figure 1-16.
1.1.2 When Switch Acts as Server for Password and HWTACACS Authentication
Network requirements
As shown in Figure 1-19, an SSH connection is required between the host (SSH client) and the switch
(SSH server) for secure data exchange. Password and HWTACACS authentication is required.
z The host runs SSH2.0 client software to establish a local connection with the switch.
z The switch cooperates with an HWTACACS server to authenticate SSH users.
