VLAN Trunking Protocol (VTP) – The Good VS the Bad Part 2:

Taking after are the parameters needed for the VTP gadgets to impart:

1-VTP Domain name

2-VTP Password: VTP uphold confirmation utilizing passed which is hashed as MD5 and utilized within VTP commercials over the system.

It would be ideal if you note that the Domain name and Password must match on the VTP empowered switches or VTP should not work giving Domain & Password jumble mistakes.

Alright at long last we are finished with the hypothesis. So how about we begin with our best, “The Configurations”.

In this arrangement we are sure to utilize 4 switches with SWITCH-1 as the VTP server while the alternate 3 will serve as VTP clients. So we should begin then;

In the wake of joining the switches we need to prepare trunk mode on the switch nearby ports on account of it is essential for the traversal of VLAN traffic.

SWITCH-1(config)#inter fa 0/1

SWITCH-1(config-if)#switchport trunk encapsulation do

SWITCH-1(config-if)#switchport trunk encapsulation dot1q

SWITCH-1(config-if)#switchport mode trunk

Note: It is not needed to run the command to initiate the trunk on the alternate close of the connection for as much as it is auto initiated when prepared toward one side.

Not with standing actuate trunk on the greater part of the switches for VLAN movement stream with the above given command. In the wake of empowering trunk mode, we will arrange VTP-Server mode on SWITCH-1 and VTP-Client mode on the remaining switches.

Since the default VTP mode on the switches is ‘Server’, we don’t need to update any of the above SWITCH-1 for server mode:

SWITCH-1#show vtp status

The above command will display different VTP parameter status, whether they are enabled or not.

Now, we will enable client mode on the other switches and will move on to configure VTP Domain name, password and version.

And we will issue the above mentioned show vtp status command to check whether our switch has been configured as client switch or not.  

Repeat the steps for all switches and enable VTP client mode of the switches. Now let’s make some change on the VTP server and check the results on the client.

Now let’s check the VLAN and VTP status on the VTP-clients and feel the magic:

This is all that you need to accomplish for VTP on our switches. Straightforward right? So attempt it and have a great time.   Just keep one thing in mind , never try to plug any switch in your office cubicle to your live network, before knowing the complete detail about your network as this enthusiasm can cost you a lot. One other thing we must keep in mind, never to plug any switch from our corporate lab into our live network, as mostly we do different sort of experiments on these switches and if anyone of them have higher revision number and same domain unluckily then you will have to spend the whole weekend in office troubleshooting the network!  So we have covered one of the major concept related to switching technologies, we will keep our journey on, will stay foolish and stay hungry.
