What is VTP and how it works?

What is VTP and how it works?

VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol used by Cisco switches to exchange VLAN information. ... VTP enables you to create the VLAN only on a single switch. That switch can then propagate information about the VLAN to every other switch on the network and cause other switches to create it.

Why VTP is used?

VTP is CISCO proprietary protocol used to maintain consistency throughout the network or user can say that synchronizing the VLAN information in same VTP domain. VTP allows you to add, delete and rename VLANs which is then propagated to other switches in the VTP domain.

What is VTP and DTP?

VTP and DTP are two different things. In summary, VTP is a protocol used to share VLAN information within a domain among connected switches. On the other hand, DTP is a protocol used to negotiate trunking between switch ports on either ends of a link.

What is VTP and its types?

Each switch can use one of four different VTP modes: VTP client mode – a switch using this mode can't change its VLAN configuration. That means that a VTP client switch cannot create or delete VLANs. ... VTP server mode – a switch using this mode can create and delete VLANs. A VTP server switch will propagate VLAN changes.

What is STP and VTP?

VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates VLAN on the whole local area network. VTP carries VLAN information to all the switches in a VTP domain. Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Local Area Networks.

What are the 3 types of VLANs?

Types of VLAN

• Management VLAN.
• Data VLAN.
• Voice VLAN.
• Default VLAN.
• Native VLAN.

How do I use VTP?

Instructions for configuring basic VTP on CISCO Switches

1. Step 1 – Creating a VTP Server. VTP has the following 3 different modes: ...
2. Step 2 – Configuring a switch as a VTP client. Enter configuration mode and use the following commands to enable client mode. ...
3. Step 3 – Configure native and trunking VLAN. ...
4. Step 4 Testing VTP.

What is VTP and STP in networking?

VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates VLAN on the whole local area network. VTP carries VLAN information to all the switches in a VTP domain. Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Local Area Networks.

What is DTP in CCNA?

The Dynamic Trunking Protocol (DTP) is a proprietary networking protocol developed by Cisco Systems for the purpose of negotiating trunking on a link between two VLAN-aware switches, and for negotiating the type of trunking encapsulation to be used.

How do I turn off VTP?

To disable VTP, enter the set vtp domain domain name mode transparent command. This disables VTP from the domain, but does not remove the domain from the switch. Use the clear config all command to remove the domain from the switch.

What does VTP stand for?

• STP stands for spanning tree protocol and VTP stads for VLAN Trunking protocol. STP is by default on in all switches to avoid loop. VTP operates in a domain where switches operates in three modes : server, client and transparent.

How to configure VTP?

• Enters configuration mode.
• Enables VTP on the device. The default is disabled.
• Specifies the name of the VTP domain that you want this device to join. The default is blank.
• Sets the VTP version that you want to use. The default is version 1.
• Sets the VTP mode to client,server,transparent,or off.
• Specifies the ASCII filename of the IFS file system file where the VTP configuration is stored.
• Specifies the password for the VTP administrative domain.
• Exits the configuration submode.
• Displays information about the VTP configuration on the device,such as the version,mode,and revision number.
• Displays information about VTP advertisement statistics on the device.
• Displays the list of VTP-enabled interfaces.
• Displays the password for the management VTP domain.
• Copies the running configuration to the startup configuration. You can configure VTP pruning on the Cisco NX-OS devices.

What is the full form of VTP?

• VTP is a Cisco proprietary protocol is used to exchange VLAN information. This type of protocol was developed to effectively manage the transfer of frames from different VLANs on a single physical line. The full form of VTP is the VLAN Trucking Protocol.

What is the function of a VTP server?

• VTP sends messages between trunked switches to maintain VLANs on these switches in order to properly trunk.
• VTP is a Cisco proprietary method of managing VLANs between switches and runs across any type of trunking mechanism.
• VTP messages are exchanged between switches within a common VTP domain.
