Chapter 38 Access Control

GS1920 Series User’s Guide

321

It relies upon certificates, public keys, and private keys.

HTTPS on the Switch is used so that you may securely access the Switch using the web
configurator. The SSL protocol specifies that the SSL server (the Switch) must always authenticate
itself to the SSL client (the computer which requests the HTTPS connection with the Switch),
whereas the SSL client only should authenticate itself when the SSL server requires it to do so.
Authenticating client certificates is optional and if selected means the SSL-client must send the
Switch a certificate. You must apply for a certificate for the browser from a Certificate Authority
(CA) that is a trusted CA on the Switch.

Please refer to the following figure.

HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the
Switch’s WS (web server).

HTTP connection requests from a web browser go to port 80 (by default) on the Switch’s WS (web
server).

Figure 235

HTTPS Implementation

Note:

If you disable HTTP in the Service Access Control screen, then the Switch blocks all

HTTP connection attempts.

38.7.2.1

HTTPS Example

If you haven’t changed the default HTTPS port on the Switch, then in your browser enter “https://
Switch IP Address/” as the web site address where “Switch IP Address” is the IP address or domain
name of the Switch you wish to access.

Internet Explorer Warning Messages

When you attempt to access the Switch HTTPS server, a Windows dialog box pops up asking if you
trust the server certificate.

You see the following Security Alert screen in Internet Explorer. Select Yes to proceed to the web
configurator login screen; if you select No, then web configurator access is blocked.
