The following table describes the labels in this screen.
Service Port For Telnet, SSH, FTP, HTTP or HTTPS services, you may change the default service
port by typing the new port number in the Server Port field. If you change the default
port number then you will have to let people (who wish to use the service) know the
new port number for that service.
Timeout Type how many minutes a management session (via the web configurator) can be left
idle before the session times out. After it times out you have to log in with your
password again. Very long idle timeouts may have security risks.
Apply Click Apply to save your changes back to the switch.
