The following entries are displayed on this screen:

 Global Config

SSL: Select Enable/Disable the SSL function on the switch.

 Certificate Download

Certificate File: Select the desired certificate to download to the switch. The

certificate must be BASE64 encoded.

 Key Download

Key File: Select the desired SSL Key to download to the switch. The key

must be BASE64 encoded.

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.

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.
