CCNA -: VLAN & VTP .:-

                                    -: VLAN:-

Togging: - This is trademark of VLAN, Let we have VLAN them for define all VLAN. We give togging.

EX:-                           VLAN –  1 -     by default

                                   VLAN – 2 -

                                   VLAN – 3 -      togging no.

Switch#show vlan

Switch(config)#vlan 10

Switch(config)#name sales

Switch(config)#exit

Switch#show vlan

                                     How to use VLAN?

Firstly we connect two pc from CISCO switch from eth0/3 and give the ip address on both pc same IP address scheme then both pc ping each other without any problem.

1. Now we want both pc will not ping each other.
2. So we will create VLAN on CISCO Switch.

VLAN: - VLAN stands for Virtual LAN its utility that use for safe IP address for waisting.

In this situation pc will be ping normally.

Switch(config)#interface F0/2

Switch(config)#switch port access vlan10

Switch(config)#no shutdown

Switch(config)#exit

Switch#wr

Now in this situation PC – A & PC – B cannot ping each other.

                                                      -: VTP:-

VTP stands for Virtual Trunking Protocol: - In this practical we create VLAN other client switch at the one location.

-: Switch 1:-

S₁(config)#vtp mode server

S₁(config)#vtp domain hcl.com

S₁(config)#int F_0/11

S₁(config)# switchport mode trunk

S₁(config)#no shutdown

S₁(config)#exit

S₁(config)#int F_0/2

S₁(config)#switchport mode trunk

S₁(config)#no shutdown

S₁(config)#exit

Switch1#show vtp status

-: Switch 2:-

S₂(config)#vtp mode client

S₂(config)#vtp domain hcl

S₂(config)#int F­_0/11

S₂(config)#switchport mode trunk

S₂(config)#no shutdown

S₂(config)#exit

Switch₂#show vtp status

-: Switch 3:-

S₃(config)#vtp mode client

S₃(config)#vtp domain hcl

S₃(config)#int F_0/1

S₃(config)#swticport mode trunk

S₃(config)#no shutdown

S₃(config)#exit

Swich₃#show vtp status

-: Switch 1:-

S₁(config)#vlan 10

S₁(config)#vlan 20

Port no 11 will be in VLAN 10

S₁(config)#int F_0/11

S₁(config)#switchport access vlan 10

S₁(config)#no shutdown

PC – 1             ping 10.10.10.1

                  ping 10.10.10.1

                        ping 10.10.10.1

                        ping 10.10.10.1

                            -: How to configure VTP client and Server:-

VTP(VLAN Trunking Protocol) is the protocol that propagate the information about which VLAN’s, exit from one switch to another switch. If VTP did not provide this information VLAN’s would have to be created on all switch individually in the network VTP is CISCO Propriety. The default mode of a switch is configuring as VTP Server in any case. The Server services are turned off.

             -:Use following command to turn it back on as VTP Server:-

Switch#vlan database

Switch(vlan)#vtp server

Switch(vlan)#exit

First create multiple VLAN with name assign multiple ports to them. Then create 802.1q trunk link between the two switches to allow communication between VLAN.

-: VTP client and server configuration:-

                                                    -: How to create VLAN:-

First enter global configuration mode to run the following command.

-: How to create VLAN₂ & VLAN₃ on a switch A:-

VTP Server:-

Switch(config)#vlan2   -        defining VLAN2

Switch(config)#vlan2 name<marketing>

Switch(config)#vlan3

Switch(config)#vlan3 name<management>

Switch(config)#exit

Switch#exit

Now assign the port2 and 3 to VLAN2. It must be done from the interface mode. Enter the following command to add port2 and 3 to VLAN2.

Switch(config)#int F_o/2

Switch(config)#switchprt access vlan2

Switch(config)#exit

Switch(config)#int F_0/3

Switch(config)#switchport access vlan2

Switch(config)#exit

Now assign the port 4 & 5 to VLAN3. Enter the following commands to add port 4 & 5 to VLAN3.

Switch(config)#int F_0/4

Switch(config)#switchport access vlan3

Switch(config)#exit

Switch(config)#int F_0/5

Switch(config)#switchport access vlan3

Switch(config)#exit

-: Configuration of VTP client on Switch B:-

Switch#vlan database

Switch#vtp client

Switch#vtp domain group1

Switch#exit

Trunking with 802.1q:-

Now create 802.1q trunk link between the two switches to allow communication between VLAN. On both switch (switch A & switch B). Type the following command with 802.1q at the fast Ethernet 0/1 interface.

SwitchA#int F_0/1

SwitchA(config)#switchport mode trunk

SwitchA(config)#switchport trunk encapsulation dot 1q

SwitchA(config)#exit

SwitchA#int F_0/1

SwitchB(config)#switchport mode trunk

SwitchB(config)#switchport trunk encapsulation dot 1q

SwitchB(config)#exit

SwitchB#int F_0/2

SwitchB(config)#switchport access vlan2

SwitchB(config)#exit

SwitchB#int F_0/3

SwitchB(config)#switchport access vlan2

SwitchB(config)#exit

SwitchB#int F_0/4

SwitchB(config)#switchport access vlan3

SwitchB(config)#exit

SwitchB#int F_0/5

SwitchB(config)#switchport access vlan3

SwitchB(config)#exit
