1. Configure the IP address of each PC
Click "PC0" in Packet Tracer, select the "IP Address Configuration" option under the "Desktop" tab in the pop-up window, the window shown below will appear, then set PC0 to "Automatically obtain", and finally follow the same steps method to set up PC1.
2. Configure switch VLAN parameters
Step 1: Enable the routing function of the Layer 3 switch.
S3560(config)#ip routing
Step 2: Establish vlan and assign ports.
S3560(config)#vlan 10
S3560(config-vlan)#name tech
S3560(config-vlan)#exit
S3560(config)#vlan 20
S3560(config-vlan)#name business
S3560(config-vlan)#exit
S3560(config)#int f0/10
S3560(config-if)#switchport mode access
S3560(config-if)#switchport access vlan 10
S3560(config-if)#exit
S3560(config)#int f0/20
S3560(config-if)#switchport mode access
S3560(config-if)#switchport access vlan 20
S3560(config-if)#exit
Step 3: Configure the routing function of the Layer 3 switch port
S3560(config)#int vlan 10
S3560(config-if)#ip address 192.168.10.1 255.255.255.0
S3560(config-if)#no shutdown
S3560(config-if)#exit
S3560(config)#int vlan 20
S3560(config-if)#ip address 192.168.20.1 255.255.255.0
S3560(config-if)#no shutdown
S3560(config-if)#exit
Step 4: View the routing table.
3. Configure the switch DHCP service
Step 1: Configure the routing function of the Layer 3 switch port.
S3560(config)#ip dhcp pool tech
S3560(dhcp-config)#network 192.168.10.0 255.255.255.0
S3560(dhcp-config)#default-router 192.168.10.1
S3560(dhcp-config)#dns-server 202.103.224.68
S3560(dhcp-config)#exit
S3560(config)#ip dhcp pool business
S3560(dhcp-config)#network 192.168.20.0 255.255.255.0
S3560(dhcp-config)#default-router 192.168.20.1
S3560(dhcp-config)#dns-server 202.103.224.68
S3560(dhcp-config)#end
Step 2: View DHCP information.
Step 3: Test the DHCP function of the layer 3 switch.
