To configure management ip address on the switch run the following commands.
Through router data is sent in the form of packet. While a router and a layer 3 switch can perform similar functions its important to distinguish a device doing the layer 3 routing so it would not be represented by a switch symbol. And unplug any ethernet cables that are plugged into any of them. Bridge symbols connect two ethernet networks into one larger extended ethernet network.
