What is DTP and VTP?

In other words, DTP allows two interconnected switches to negotiate the operating mode of a link – either an access link or a trunk. VTP is responsible for synchronizing the VLAN database across multiple switches.

What is DTP and its advantages?

Increased productivity. Reduced production costs. Improved appearance of documents. Enhanced creativity with an element of fun. Ability to produce customized documents.

What are the features of DTP?

Desktop publishing software (DTP) is used to create documents like leaflets, brochures and newsletters. Modern word processors have the basic features of DTP software but features such as templates and frames make DTP software better for complex page layouts .

What VLAN does DTP use?

VLAN trunks formed using DTP may utilize either IEEE 802.1Q or Cisco ISL trunking protocols. DTP should not be confused with VTP, as they serve different purposes. VTP communicates VLAN existence information between switches. DTP aids with trunk port establishment.

What is trunking mode?

TRUNK MODE. ACCESS MODE. Terminology. A trunk port can carry traffic in one or more VLANs on the same physical link. Trunked ports differentiate Vlans by either adding a tag to the packet (802.1Q) or encapsulation the packet (ISL).

How do I turn off DTP?

The first way is configuring the switchport as an access port by using the command switchport mode access. This will disable DTP and allow the switchport to operate only in the configured VLAN, if none is configured by default it will be placed into VLAN_1.

Why is DTP used?

Desktop publishing (DTP) is the creation of documents using page layout software on a personal (“desktop”) computer. … This technology allows individuals, businesses, and other organizations to self-publish a wide variety of content, from menus to magazines to books, without the expense of commercial printing.

What’s DTP default in a switch?

The the newer switch has “dynamic auto” as default DTP and the older switch as “Dynamic Desirable”. Dynamic Auto — Makes the Ethernet port willing to convert the link to a trunk link. The port becomes a trunk port if the neighboring port is set to trunk or dynamic desirable mode.

Is DTP enabled by default?

DTP is enabled by default on all modern Cisco switches. … If all it takes is the right DTP packet to form a trunk from an access port, an intruder can easily inject traffic into whatever VLANs are allowed on the port (by default, all of them).

What does trunking mean?

In telecommunications, trunking is a way to provide network access to many clients by sharing a set of lines or frequencies instead of providing them individually. This is analogous to the structure of a tree with one trunk and many branches.

Which switch port mode prevents DTP frames from being sent?

switchport nonegotiate – This mode prevents the interface from generating DTP frames. This command is used only when the switchport mode is access or trunk. You must manually configure the neighboring interface as a trunk interface to establish a trunk link.

What is native VLAN?

native vlan means that device will never put/insert tag (VLAN ID, in you case “VLAN ID:2”) on Ethernet frame when it leaves port and also when Ethernet frame without tag go into that port device will put/insert tag defined by native vlan ( in you case VLAN ID:2). Of course native vlan relates to trunk port.
