There is unauthorized access to my Switch through telnet, HTTP and SSH.
Go to the MONITOR > System Log screen to check for logs of unauthorized access to your Switch. To
avoid unauthorized access, configure the secured client setting in the SECURITY > Access Control >
Remote Management screen for telnet, HTTP and SSH (see Section 66.3 on page 444). Computers not
belonging to the secured client set cannot get permission to access the Switch.
80.3 Switch Configuration
I lost my configuration settings after I restart the Switch.
Make sure you save your configuration into the Switch’s non-volatile memory
each time you make changes. Click Save at the top right of the Web Configurator
to save the configuration permanently. See also Section 78.12 on page 546 for
more information about how to save your configuration.
I accidentally unplugged the Switch. I am not sure which configuration file will be loaded.
If you plug the power cable back to the Switch, it will reboot and load the configuration file that was
used the last time. For example, if Config 1 was used on the Switch before you accidentally unplugged
the Switch, Config 1 will be loaded when rebooting.
