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 37.10 on page 354 ). Computers not belonging to the secured client set
cannot get permission to access the Switch.

at the top right corner of the Web Configurator to save the
configuration permanently. See also
Section 36.6 on page 331
for more information about how to save your configuration.
