M4100 Series Managed Switch
The Authentication List field displays the authentication list that HTTP is using.
8. Select the HTTP Access Disable or Enable radio button.
This specifies whether the switch can be accessed from a web browser. If you choose to
enable web mode, you can manage the switch from a web browser. The factory default is
enabled.
9. Select the Java Mode Disable or Enable radio button.
This disables or enables the Java applet that displays a picture of the switch in the Device
view tab of the System tab. If you run the applet, you can click the picture of the switch to
select configuration screens instead of using the navigation tree on the left side of the
screen. The factory default is Enable.
10. In the HTTP Session Soft Timeout (Minutes) field, set the inactivity time-out for HTTP
sessions.
The value must be in the range of 1 to 60 minutes. The default value is 60 minutes. The
currently configured value is shown when the screen displays.
11. In the HTTP Session Hard Timeout (Hours) field, set the hard time-out for HTTP sessions.
This time-out is unaffected by the activity level of the session. The value must be in the
range of 1 to 168 hours. The default value is 24 hours. The currently configured value is
shown when the screen is displayed.
12. In the Maximum Number of HTTP Sessions field, set the maximum allowable number of
HTTP sessions.
The value must be in the range of 0 to 16. The default value is 16. The currently
configured value is shown when the screen is displayed.
Configure HTTPS Settings
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.
You can configure the settings for HTTPS communication between the management station
and the switch.
To configure HTTPS settings:
1. Prepare your computer with a static IP address in the 169.254.100.0 subnet, for
example, 169.254.100.201.
2. Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on
the switch.
3. Launch a web browser.
4. Enter the IP address of the switch in the web browser address field.
The default IP address of the switch is 169.254.100.100.
