LABEL DESCRIPTION
Services Services you may use to access the Switch are listed here.
Active Select this option for the corresponding services that you want to allow to access the
Switch.
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 to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click Cancel to begin configuring this screen afresh.
