such as duplicate VLAN names or incorrect VLAN-type specifications. VTP minimizes misconfigurations and configuration. VTP helps you simplify management of the VLAN data base across multiple switches  VTP allows for centralized changes that are communicated to all other switches in the network 2 .

the VLAN is distributed through all switches in the domain. Cisco layer 2 protocol  Manages the addition .  Reduces the need to configure the same VLAN everywhere  Available on most of the Cisco Catalyst family Products 3 .wide basis  When you configure a new VLAN on VTP Switch(server).deletion and renaming of VLANs on a network.

dat 4 . VTP stores VLAN configurations in the VLAN database called vlan.

 Virtual Local Area Network (VLAN) Trunk Protocol(VTP) reduces administration o a switched network  Minimizes the problems caused by incorrect configurations and configuration inconsistencies 5 .

 Domain is defined by its name.  Switch can be linked but not part of domain.  Proprietary to Cisco. so all switches in domain must be Cisco switches. Group of layer 2 switches sharing VLAN data.  Each switch can belong to only one domain.  Ends at router or layer 3 switch. 6 .

Sends VLAN information to other switches.forward VTP traffic but do not originate or use it. Transparent.A switch can be configured in one of three modes Server.receives VLAN information and forward it to other switches. They can have their own VLANs.default mode. Client.not shared with other switches 7 .

 Synchronizes VLAN configuration with latest information received from other switches in the management domain  Does Not save VLAN configuration in non volatile RAM(NVRAM) 8 .change or delete VLANs on command-line interface (CLI)  Forwards advertisements to other switches. Cannot create .

modifies and delete VLANs. and delete VLAN and VLAN configuration parameters for the entire domain.  VTP servers send VTP messages out to all trunk ports.  Send and forwards advertisements to others switches  Synchronizes VLAN configuration with latest information received from other switches in the management port  Saves VLAN configuration in NVRAM(non volatile ram)  VTP servers can create. 9 . Create.  VTP servers save VLAN configuration information in the switch NVRAM. modify.

 A transparent switch will not modify its database when updates are received. 10 .  Does not synchronize its VLAN configuration with information received from other switches in management domain  Saves VLAN configuration in NVRAM. nor will the switch send out an update indicating a change in its VLAN status.  Switches in VTP transparent mode forward VTP advertisements but ignore information contained in the message.delete and modifies VLAN only on the local switch  Forwards VTP advertisements received from other switches in the same management domain. VTP is disabled on a transparent switch.  Except for forwarding VTP advertisements. Create .
