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://192.168.1.1. 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.
22
SSL:
Select Enable/Disable the SSL function on the switch.
Certificate File:
Select the desired certificate to download to the switch. The
certificate must be BASE64 encoded.
Key File:
Select the desired SSL key to download to the switch. The key
must be BASE64 encoded.
Choose the menu System→Access Security→SSL Config to load the following page.

The following entries are displayed on this screen:

Certificate Download
Key Download
Note:
1. The SSL certificate and key downloaded must match each other; otherwise the HTTPS
connection will not work.
2. The SSL certificate and key downloaded will not take effect until the switch is rebooted.
3. To establish a secured connection using https, please enter https:// into the URL field of the
browser.
4. It may take more time for https connection than that for http connection, because https
connection involves authentication, encryption and decryption etc.
4.4.3 SSH Config
As stipulated by IFTF (Internet Engineering Task Force), SSH (Secure Shell) is a security protocol
established on application and transport layers. SSH-encrypted-connection is similar to a telnet
connection, but essentially the old telnet remote management method is not safe, because the
password and data transmitted with plain-text can be easily intercepted. SSH can provide
information security and powerful authentication when you log on to the switch remotely through
an insecure network environment. It can encrypt all the transmission data and prevent the
information in a remote management being leaked.
23
SSH:
Select Enable/Disable SSH function.
Protocol V1:
Select Enable/Disable SSH V1 to be the supported protocol.
Protocol V2:
Select Enable/Disable SSH V2 to be the supported protocol.
Idle Timeout:
Specify the idle timeout time. The system will automatically
release the connection when the time is up. The default time is
120 seconds.
Max Connect:
Specify the maximum number of the connections to the SSH
server. No new connection will be established when the number
of the connections reaches the maximum number you set. The
default value is 5.
Key Type:
Select the type of SSH key to download. The switch supports
three types: SSH-1 RSA, SSH-2 RSA and SSH-2 DSA.
Key File:
Select the desired key file to download.
Comprising server and client, SSH has two versions, V1 and V2 which are not compatible with
each other. In the communication, SSH server and client can auto-negotiate the SSH version and
the encryption algorithm. After getting a successful negotiation, the client sends authentication
request to the server for login, and then the two can communicate with each other after successful
authentication. This switch supports SSH server and you can log on to the switch via SSH
connection using SSH client software.
SSH key can be downloaded into the switch. If the key is successfully downloaded, the certificate
authentication will be preferred for SSH access to the switch.
Choose the menu System→Access Security→SSH Config to load the following page.

Download:
Click the Download button to down the desired key file to the
switch.
Note:
1. Please ensure the key length of the downloaded file is in the range of 256 to 3072 bits.
2. After the key file is downloaded, the user’s original key of the same type will be replaced. The
wrong uploaded file will result in the SSH access to the switch via Password authentication.
Application Example 1 for SSH:
Network Requirements
1. Log on to the switch via password authentication using SSH and the SSH function is enabled
on the switch.
2. PuTTY client software is recommended.
Configuration Procedure
1. Open the software to log on to the interface of PuTTY. Enter the IP address of the switch into
Host Name field; keep the default value 22 in the Port field; select SSH as the Connection
type.
2. Click the Open button in the above figure to log on to the switch. Enter the login user name and
password, and then you can continue to configure the switch.
