Secure HTTP Configuration
Secure HTTP enables the transmission of HTTP over an encrypted Secure Sockets Layer
(SSL) or Transport Layer Security (TLS) connection. When you manage the switch by using a
Web interface, secure HTTP can help ensure that communication between the management
system and the switch is protected from eavesdroppers and man-in-the-middle attacks.
Use the Secure HTTP Configuration page to configure the settings for HTTPS
commu
nication between the management station and the switch.
To display the Secure HTTP Configuration page, click Se
curity  Access, and then click the
HTTPS
