Understanding J-Web User Interface Sessions
You establish a J-Web session with the switch through an HTTP-enabled or HTTPS-enabled Web browser. To use HTTPS, you must have installed a certificate on the switch and enabled HTTPS. See Generating SSL Certificates to Be Used for Secure Web Access (EX Series Switch).
When you attempt to log in through the J-Web interface, the switch authenticates your username with the same methods used for Telnet and SSH.
If the switch does not detect any activity through the J-Web interface for 15 minutes, the session times out and is terminated. You must log in again to begin a new session.
To explicitly terminate a J-Web session at any time, click Logout in the top pane.
