24.7 Introduction to HTTPS

HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web protocol that
encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-level protocol that enables secure
transactions of data by ensuring confidentiality (an unauthorized party cannot read the transferred data),
authentication (one party can identify the other party) and data integrity (you know if data has been changed).
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 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.
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.

If you disable HTTP in the Service Access Control screen, then the switch blocks all HTTP
24.7.1 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.
The HTTPS proxy server listens on port 443 by default. If you change the HTTPS proxy server port to a different
number on the switch, for example 8443, then you must notify people who need to access the switch web
configurator to use "https:// switch IP Address:8443" as the URL.
