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.
