4.4.2 SSL Config

SSL (Secure Sockets Layer), a security protocol, is to provide a secure connection for the
application layer protocol (e.g. HTTP) communication based on TCP. SSL is widely used to secure
the data transmission between the Web browser and servers. It is mainly applied through
ecommerce and online banking.
SSL mainly provides the following services:
1. Authenticate the users and the servers based on the certificates to ensure the data are
transmitted to the correct users and servers;
2. Encrypt the data transmission to prevent the data being intercepted;
3. Maintain the integrality of the data to prevent the data being altered in the transmission.
Adopting asymmetrical encryption technology, SSL uses key pair to encrypt/decrypt information. A
key pair refers to a public key (contained in the certificate) and its corresponding private key. By
default the switch has a certificate (self-signed certificate) and a corresponding private key. The
Certificate/Key Download function enables the user to replace the default key pair.
After SSL is effective, you can log on to the Web management page via https://192.168.0.1. For
the first time you use HTTPS connection to log into the switch with the default certificate, you will
be prompted that "The security certificate presented by this website was not issued by a trusted
certificate authority" or "Certificate Errors". Please add this certificate to trusted certificates or
continue to this website.
On this page you can configure the SSL function.
Choose the menu System→Access Security→SSL Config to load the following page.
The field can be available for configuration only when Port-based
mode is selected. Only the users connected to these ports you set
here are allowed for login.
If you do nothing with the Web management page within the
timeout time, the system will log out automatically. If you want to
reconfigure, please login again.
Select Enable/Disable the Number Control function.
Enter the maximum number of the users logging on to the Web
management page as Admin.
Enter the maximum number of the users logging on to the Web
management page as Guest.
