Pop-up Windows, JavaScripts and Java Permissions
In order to use the web configurator you need to allow:
• Web browser pop-up windows from your device.
• JavaScripts (enabled by default).
• Java permissions (enabled by default).
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 Display button in the System Log field in the Management > Diagnostic screen to
check for unauthorized access to your Switch. To avoid unauthorized access, configure the
secured client setting in the Management > Access Control > Remote Management screen
for telnet, HTTP and SSH (see Section 39.10 on page 386). Computers not belonging to the
secured client set cannot get permission to access the Switch.
46.3 Switch Configuration
I lost my configuration settings after I restart the Switch.
Make sure you save your configuration into the
Switch’s nonvolatile memory each time you make
changes. Click Save at the top right corner of the
web configurator to save the configuration permanently. See also Section 38.3 on
page 360 for more information about how to save your configuration.
