Hi Frank
In order for us to help you, please post the entire configuration file of the switch.
You have to login via console to the switch, acces the CLI (if the menu appears, use option 5) and issue the following command:
Switch# show config
As for the /24 part of the ip address it represents the netmask. /24 stands for 255.255.255.0
192.168.10.2 / 24 is the same thing as 192.168.10.2 / 255.255.255.0
24 bits are used to create the netmask and you get a type C IP address.
