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 32.7 on page 290 ). Computers not belonging to the secured client set
cannot get permission to access the Switch.
39.3 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 31.5 on
page 279 for more information about how to save your configuration.
