DESCRIPTION
Services you may use to access the switch are listed here.
Select this option for the corresponding services that you want to allow to access the
switch.
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.
Type how many minutes (between 1 and 255) 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.
Click Apply to save your changes back to the switch.
Click Cancel to begin configuring this screen afresh.
