Presentation of CCNA VlANs in English Voice

Describe Virtual LANs.

Describe Frame Tagging.

Describe Inter-Switch Link Routing.

Describe Virtual Trunking Protocol.

A Virtual Local Area Network (VLAN) is a logical grouping of network users and resources connected to administratively defined ports on a switch.

By creating VLANs, you are able to create smaller broadcast domains within a switch by assigning different ports in the switch to different subnetworks.

A VLAN is treated like its own subnet or broadcast domain. This means that frames broadcasted onto a network are only switched between ports in the same VLAN.

Using virtual LANs, you're no longer confined to creating workgroups by physical locations.

VLANs can be organized by location, function, department, or even the application or protocol used, regardless of where the resources or users are located.

In this chapter, you will learn what a VLAN is and how VLAN memberships are used in a switched internetwork.

Also, I'll discuss how Virtual Trunk Protocol (VTP) is used to update switch databases with VLAN information.

Trunking FastEthernet links will also be discussed. Trunking allows you to send information about all VLANs across one link.
