What is VLAN trunk protocol do?

Virtual local area network (VLAN) trunking Protocol or VTP is a proprietary protocol from Cisco that allows networks to send network functionality through all of the switches in a domain. This technique eliminates the need for multiple configurations for VLANs throughout the system.

What is the trunking protocol used?

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. It works on Layer 2 of the OSI model.

What is VTP and why is is used?

VTP is a protocol used to distribute and synchronize identifying information about VLANs configured throughout a switched network. Configuration changes made to the VLANs on a single VTP server switch are propagated across Trunk links to all trunk-connected switches in the network.

What is the main function of VLAN?

VLANs reduce the incidence of collisions and decrease the number of network resources wasted by acting as LAN segments. Data packets sent from a workstation in a segment are transferred by a bridge or switch, which will not forward collisions but will send on broadcasts to every network devices.

How we can create VLAN?

Complete these steps in order to create a VLAN.

1. Decide whether to use VTP in your network.
2. After you set and verify the VTP domain, begin to create VLANs on the switch.
3. Issue the show vlan command in order to ensure that the VLAN is created.
4. You can add ports (interfaces) in the newly created VLAN.

How can configure VLAN on a switch port?

Switch Controller and Overview tab.

list view or VLAN view.

Make sure that the port enable is toggled to ON state.

Port shield it to interface X5 as that interface has VLAN 70 and 75 configured.

Set the option VLAN trunk to Enable.

What is VLAN trunk mode in Hyper-V?

Hyper-V Virtual Switch also provides support for VLAN trunk mode. Trunk mode provides network services for a Virtual Machine with the ability to see traffic from multiple VLANs , in other words the virtual switch port receives traffic from all VLANs that you configure in an allowed VLAN list. You can also configure a switch port that is connected to a VM, but is not bound to the underlying NIC for trunk mode.

What is the purpose of VLAN support on a switch?

With a VLAN, that traffic is handled more efficiently by network switches . VLANs also bring security benefits to larger networks by allowing greater control over which devices have local access to each other. Wi-Fi guest networks are often implemented using wireless access points that support VLANs.

What is a non-routable VLAN?

A non routeable VLAN is simply a normal VLAN that lacks a router, thereby not being routable to other networks. One common use of non-routable VLANs is for storage networks.
