Switch Configuration - ZyXEL Communications GS1900-8 User Manual

I cannot see some of Advanced Application submenus at the bottom of the navigation
panel.
The recommended screen resolution is 1024 by 768 pixels. Adjust the value in your computer and
then you should see the rest of Advanced Application submenus at the bottom of the navigation
panel.
There is unauthorized access to my Switch via telnet, HTTP and SSH.
Click the Maintenance > Diagnostics screen to check for unauthorized access to your Switch. To
avoid unauthorized access, configure the secured client setting in the Configuration >
Management > Remote Access Control screen for telnet, HTTP and SSH (see
page 211). Computers not belonging to the secured client set cannot get permission to access the
Switch.
