Step 2: Verify connectivity between PCs on the same network.
- PC1 can ping PC4
- PC2 can ping PC5
- PC3 can ping PC6
Part 2: Configure VLANs
Step 1: Create and name VLANs on S1.
• VLAN 10: Faculty/Staff
S1#(config)# vlan 10 S1#(config-vlan)# name Faculty/Staff
• VLAN 20: Students
• VLAN 30: Guest(Default)
• VLAN 99: Management&Native
• VLAN 150: VOICE
S1(config-vlan)#vlan 20 S1(config-vlan)#name Students S1(config-vlan)#vlan 30 S1(config-vlan)#name Guest(Default) S1(config-vlan)#vlan 99 S1(config-vlan)#name Management&Native S1(config-vlan)#vlan 150 S1(config-vlan)#name VOICE
Step 2: Verify the VLAN configuration.

150 VOICE active
1002 fddi-default active
1003 token-ring-default active
1004 fddinet-default active
1005 trnet-default active
Step 3: Create the VLANs on S2 and S3.
S2
S2(config)#vlan 10 S2(config-vlan)#name Faculty/Staff S2(config-vlan)#vlan 20 S2(config-vlan)#name Students S2(config-vlan)#vlan 30 S2(config-vlan)#name Guest(Default) S2(config-vlan)#vlan 99 S2(config-vlan)#name Management&Native S2(config-vlan)#vlan 150 S2(config-vlan)#name VOICE
S3
S3(config)#vlan 10 S3(config-vlan)#name Faculty/Staff S3(config-vlan)#vlan 20 S3(config-vlan)#name Students S3(config-vlan)#vlan 30 S3(config-vlan)#name Guest(Default) S3(config-vlan)#vlan 99 S3(config-vlan)#name Management&Native S3(config-vlan)#vlan 150 S3(config-vlan)#name VOICE
Step 4: Verify the VLAN configuration.

Part 3: Assign VLANs to Ports
• VLAN 10: FastEthernet 0/11
S2(config)# interface f0/11 S2(config-if)# switchport mode access S2(config-if)# switchport access vlan 10
• VLAN 20: FastEthernet 0/18
• VLAN 30: FastEthernet 0/6
S2(config-if)#interface f0/18 S2(config-if)#switchport mode access S2(config-if)#switchport access vlan 20 S2(config-if)#interface f0/6 S2(config-if)#switchport mode access S2(config-if)#switchport access vlan 30 S2(config-if)#
Step 2: Assign VLANs to the active ports on S3.
• VLAN 10: FastEthernet 0/11
• VLAN 20: FastEthernet 0/18
• VLAN 30: FastEthernet 0/6
S3(config)#interface f0/11 S3(config-if)#switchport mode access S3(config-if)#switchport access vlan 10 S3(config-if)#interface f0/18 S3(config-if)#switchport mode access S3(config-if)#switchport access vlan 20 S3(config-if)#interface f0/6 S3(config-if)#switchport mode access S3(config-if)#switchport access vlan 30
Step 3: Assign the VOICE VLAN to FastEthernet 0/11 on S3.
S3(config)# interface f0/11 S3(config-if)# mls qos trust cos S3(config-if)# switchport voice vlan 150
Step 4: Verify loss of connectivity.
