Configure Vlan vtp server stp dtpIn our pervious article you learnt about the feature of switching. To read these articles you can follow these links.
In this tutorial I will demonstrate that how can you
To complete these lab either create a topology as shown in figure or download this file and load it in packet tracer
TaskYou are the administrator at ComputerNetworkingNotes.com. company have two department sales and management. You have given three pc for sales and three pc in management. You created two VLAN. VLAN 10 for sales and VLAN20 for management. For backup purpose you have interconnected switch with one extra connection. You have one router for intera VLAN communications. Let's start configuration first assign IP address to all pc's VLAN Trunking ProtocolConfigure VTP ServerWe will first create a VTP Server so it can automatically propagate VLAN information to other switch. Double click on Switch1 and select CLI. Set hostname to S1 and create VTP domain name example and set password to vinita ( Remember password is case sensitive ). Switch 1 Switch>enable Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#hostname S1 S1(config)#vtp mode server Device mode already VTP SERVER. S1(config)#vtp domain example Changing VTP domain name from NULL to example S1(config)#vtp password vinita Setting device VLAN database password to vinita Configure VTP clientsOnce you have created a VTP domain. Configure remaining Switch to Client mode. Switch 2 Switch>enable Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#hostname S2 S2(config)#vtp mode client Setting device to VTP CLIENT mode. S2(config)#vtp domain example Changing VTP domain name from NULL to example S2(config)#vtp password vinita Setting device VLAN database password to vinita S2(config)# Switch 3 Switch>enable Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#hostname S3 S3(config)#vtp mode client Setting device to VTP CLIENT mode. S3(config)#vtp domain example Changing VTP domain name from NULL to example S3(config)#vtp password vinita Setting device VLAN database password to vinita S3(config)# Dynamic Trunking ProtocolConfigure DTP portAll Switch ports remain by default in access mode. Access port can not transfer the trunk frame. Change mode to trunk on all the port those are used to interconnect the switches Switch 1 S1(config)#interface fastEthernet 0/24 S1(config-if)#switchport mode trunk %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/24, changed state to down %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/24, changed state to up S1(config-if)#exit S1(config)#interface gigabitEthernet 1/1 S1(config-if)#switchport mode trunk S1(config-if)#exit S1(config)#interface gigabitEthernet 1/2 S1(config-if)#switchport mode trunk %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/2, changed state to down %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/2, changed state to up S1(config-if)#exit S1(config)# Switch 2 S2(config)#interface gigabitEthernet 1/1 S2(config-if)#switchport mode trunk %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/1, changed state to down %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/1, changed state to up S2(config-if)#exit S2(config)#interface gigabitEthernet 1/2 S2(config-if)#switchport mode trunk S2(config-if)#exit S2(config)#interface fastEthernet 0/23 S2(config-if)#switchport mode trunk %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/23, changed state to down %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/23, changed state to up S2(config-if)#exit S2(config)#interface fastEthernet 0/24 S2(config-if)#switchport mode trunk S2(config-if)#exit Switch 3 S3(config)#interface fastEthernet 0/24 S3(config-if)#switchport mode trunk S3(config-if)#exit S3(config)#interface gigabitEthernet 1/1 S3(config-if)#switchport mode trunk S3(config-if)#exit Virtual LAN (VLAN)Create VLANAfter VTP server configuration its time to organize VLAN. We need only to create VLAN on VTP server and reset will be done by VTP Server automatically. Switch 1 S1(config)#vlan 10 S1(config-vlan)#exit S1(config)#vlan 20 S1(config-vlan)#exit S1(config)# As we have already configure VTP server in our network so we don't need to create VLAN on S2 or S3. We need only to associate VLAN with port. Assign VLAN membershipSwitch 1 S1(config)#interface fastEthernet 0/1 S1(config-if)#switchport access vlan 10 S1(config-if)#interface fastEthernet 0/2 S1(config-if)#switchport access vlan 20 Switch 2 S2(config)#interface fastEthernet 0/1 S2(config-if)#switchport access vlan 10 S2(config-if)#interface fastEthernet 0/2 S2(config-if)#switchport access vlan 20 Switch 3 S3(config)#interface fastEthernet 0/1 S3(config-if)#switchport access vlan 10 S3(config-if)#interface fastEthernet 0/2 S3(config-if)#switchport access vlan 20 Now we have two working vlan. To test connectivity do ping form 10.0.0.2 to 10.0.0.3 and 10.0.0.4. if you get successfully replay then you have successfully created VLAN and VTP server. Spanning-Tree ProtocolIn this configuration STP will block these ports F0/24 of S1 , F0/23 and F0/24 of S2 and F0/24 of S3 to avoid loop at layer to two. Verify those ports blocked due to STP functions Verify STP portsSwitch 2

You can test STP protocols status on S1 and S3also with Router on StickAt this point of configurations you have two successfully running VLAN but they will not connect each other. To make intra VLAN communications we need to configure router . To do this double click on router and select CLI. Configure intra VLANRouter Router>enable Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#interface fastEthernet 0/0 Router(config-if)#no ip address Router(config-if)#no shutdown Router(config-if)#exit Router(config)#interface fastEthernet 0/0.10 Router(config-subif)#encapsulation dot1Q 10 Router(config-subif)#ip address 10.0.0.1 255.0.0.0 Router(config-subif)#exit Router(config)#interface fastEthernet 0/0.20 Router(config-subif)#encapsulation dot1Q 20 Router(config-subif)#ip address 20.0.0.1 255.0.0.0 Router(config-subif)#exit To test connectivity between different vlan do ping form any pc to all reaming pc. it should be ping successfully. If you have error download this configured topology and cross check that where you have committed mistake. Configured VLAN VTP STP topology VLAN VTP Server STP DTP command reference sheet
