2. © 2006 Cisco Systems, Inc. All rights reserved.Cisco PublicITE 1 Chapter 6 2 Objectives  VTP Concept  Describe the operation of VTP: VTP domains, VTP Modes, VTP Advertisements, and VTP Pruning.  Configure VTP on the switches in a converged network.

3. © 2006 Cisco Systems, Inc. All rights reserved.Cisco PublicITE 1 Chapter 6 3 VTP Concept: Why VTP  You have learned how to create and manage VLANs and trunks on a single switch.  But if you have many switches how to manage the VLANs?

4. © 2006 Cisco Systems, Inc. All rights reserved.Cisco PublicITE 1 Chapter 6 4 VTP Concept: What is VTP?  The VLAN Trunking Protocol (VTP) is to maintain VLAN configuration consistency across the entire network  VTP allows a network manager to configure a switch so that it will propagate VLAN configurations to other switches in the network.4.1.1(2)

5. © 2006 Cisco Systems, Inc. All rights reserved.Cisco PublicITE 1 Chapter 6 5 VTP Components: VTP domain  Switches are organized into logical groups called VTP management domains.  The VLAN information within a VTP domain is propagated through trunk links and is updated via the VTP, allowing all switches within a particular domain to maintain identical VLAN databases.

8. © 2006 Cisco Systems, Inc. All rights reserved.Cisco PublicITE 1 Chapter 6 8 Describe the Operation of VTP  VTP domain: For a VTP server or client switch to participate in a VTP-enabled network, it must be a part of the same domain.  VTP Versions: VTP has three versions, 1, 2, and 3. Only one VTP version is allowed in a VTP domain. The default is VTP version 1.

All rights reserved.Cisco PublicITE 1 Chapter 6 28 Summary  VTP is a Cisco proprietary protocol used to exchange VLAN information across trunk links.  A switch can be in one of 3 VTP operating modes Client Cannot create, modify or delete VLAN Server Can create, modify & delete VLAN Transparent Can create, modify, & delete LOCAL VLAN Forwards VTP advertisements.
