What protocol is used in VLAN trunk?

VTP
VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates the definition of Virtual Local Area Networks (VLAN) on the whole local area network. To do this, VTP carries VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over 802.1Q, and ISL trunks.

What are the VLAN Trunking Protocol VTP modes?

VTP modes – There are 3 modes:

Server – The switches are set to this mode by default.
Client – In this mode, the switches receives the updates and can also forward the updates to other switches(which are in same VTP domain).
Transparent – This mode only forwards the VTP summary advertisements through trunk link.

What are the configurations required in VTP?

All switches in a VTP domain must run the same VTP version. All switches in a VTP domain has the same VTP password, if there is any. When you move a VTP mode of a switch from Transparent to Server, VLANs configured on the VTP Transparent switch should exist on the Server switch.

What is native VLAN?

An Access port (or “untagged port” in the non Cisco world) is a switch port which carries traffic for only one VLAN. Access ports do not require a VLAN tag, since all incoming and outgoing frames belong to a single VLAN. The Native VLAN is simply the one VLAN which traverses a Trunk port without a VLAN tag.

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.
