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 40.11 on page 323). Computers not belonging to the secured client set
cannot get permission to access the Switch.
47.3 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 39.3 on page 295 for more information about how to
save your configuration.
