Let me talk about the problem I encountered when logging in: I created a Cisco account, but the Cisco software cannot log in to
Sorry, we can't find a NetAcad account associated with this Cisco account. Let us help you get back on track. If you already have a NetAcad account, please log out and log back in with the email address you used for Networking Academy. If this doesn't work, please visit the login help page for tips and to get support. To learn more about Cisco Networking Academy and to create an account, please visit at our home page.
So I searched for the answer, the reason is:
Cisco also has a network academy, the software requires the Cisco account and the network academy account to be bound to the Cisco software to log in normally. The solution is attached below.
The difference between 7.0 and 6.2 is that when the installation is complete and the PT is opened, the login interface of Cisco Network Academy will appear. Here users can choose two login methods. The first is the normal user name login, and the other is the guest login. It should be noted here that you cannot use PT without logging in, and the program will automatically exit.
I don't recommend using tourists to log in. It is recommended to register for a Cisco Network Academy account. The guest login has the following problems:
1. The login interface of the Cisco Network Academy will appear every time the PT is turned on.
2. It is said that the visitor login method is used. Although PT can be used, the official limits the number of times the topology can be saved. It's very upset to think about it!
I have seen a lot of people on the Internet reporting the problem of failed login to the Cisco Cyber Academy account. There is one thing that everyone does not know, that is, the Cisco account and the Cisco Network Academy account are registered separately and cannot be mixed.
The following are the respective registration methods:
1: Cisco account registration: https://www.cisco.com
2: Cisco Netacad account registration: Cisco Netacad official website https://www.netacad.com/
