Waxaa laga yaabaa inaadan maqlin VLAN ( Shabakadda Deegaanka Virtual^{(Virtual Local Area Network)} ). Waa wax marka hore loo isticmaalo ganacsiyada waaweyn ee aduunka. Haddii aad xiisaynayso inaad furto ganacsi u baahan VLANs , waxaad u baahan doontaa inaad wax badan ka barato. Ma aha oo kaliya, haddii aad xiisaynayso CCNA , markaa hubaal waxaad u baahan doontaa inaad fahamto waxa VLAN ku saabsan yahay. Laakiin ha werwerin, waxaanu ku haynaa dhammaan macluumaadka aad uga baahan tahay maqaalkan.

Waa maxay VLAN?

Nuxur ahaan, VLAN waa shabakad gaar ah oo laga sameeyay shabakado badan oo deegaanka ah. Haddii dhowr qalab lagu furo shabakado badan, waa la isku dari karaa si loo abuuro hal shabakad macquul ah. Natiijada isku-dhafkan waxay noqotaa LAN Virtual ah oo loo maamulo si la mid ah LAN jireed .

Iyadoo aan la helin VLAN , baahinta kasta oo laga soo diro hal martigeliyaha waxay gaari kartaa dhammaan aaladaha shabakada halkii ay doorbidi lahayd. Tani waa dhibaato sababtoo ah waxay kordhin kartaa culeyska shaqada ee CPU , taas oo iyaduna keenta hoos u dhac ku yimaada shabakadaada guud waxayna yaraynaysaa ammaanka ilaa ugu yaraan.

Waa maxay sababta aan u isticmaalno VLANs?

• Yaraynta khataraha amniga:^{(Reduction of security risks:)} Marka ay timaado hoos u dhigista khataraha amniga, VLAN waxay tan samaysaa iyadoo hoos u dhigaysa tirada martida loo yahay ee heli kara koobiyada fiimyada shixnaduhu daadad karaan.
• Hagaajinta amniga:^{(Improve security:)} Si loo hagaajiyo amniga, waxaad ku hayn kartaa martida loo yahay macluumaadka xasaasiga ah ee VLAN gaar ah .
• Samee isbeddelada shabakada:^{(Create network changes:)} Adigoo u habeynaya deked VLAN ku habboon , waxaad si sahlan ku gaari kartaa isbeddelada shabakadda.
• Kordhi aagagga baahinta:^{(Increase broadcast domains:)} Haddii aad rabto inaad kordhiso tirada xayndaabka baahinta adigoo yareynaya cabbirkooda, markaa betka ugu fiican waa inaad isticmaasho VLAN .
• Dabacsanaan la hagaajiyay:^{(Improved flexibility:)} Halkii laga lahaa in la abuuro naqshado shabakadeed oo ay ku kooxeeyaan isticmaalayaasha goobaha jireed, VLAN waxay suurtogal ka dhigaysaa dhaqdhaqaaq aad u dabacsan oo loogu talagalay shabakadaha iyada oo la kooxeynaya isticmaalayaasha waaxaha.

Sida loo habeeyo VLAN

Hadda, marka la eego isku xidhka Shabakadda Aagga Deegaanka^{(Local Area Network)} Virtual , waa inaad ogaataa dhowr waxyaalood. Tusaale ahaan, dhammaan dekedaha ku yaal beddelka waxay ku yaalliin VLAN 1 . Haddii aad rabto inaad tan xaqiijiso, fadlan ku qor amarka show vlan ka IOS awood habka beddelka.

Marka la eego abuurista VLAN iyo ku meelaynta dekedda beddelka ee VLAN , waxaa jira laba tillaabo oo muhiim ah oo ay tahay inaad raacdo:

Marka hore, samee VLAN adiga oo isticmaalaya vlan NUMBER amarka caalamiga ah

Markaad ku meelaynayso beddelka dekedda, waa inaad isticmaashaa labada amar-hoosaad ee interface. Midka koowaad waa, helitaanka amarka, halka kan labaadna uu yahay, beddelka marinka gelitaanka ee vlan NUMBER Command.

Amarka kowaad wuxuu ku saabsan yahay in la qeexo in interface-ku la heli karo, halka kan labaadna loogu talagalay in lagu meeleeyo interface-ka VLAN .

Waa maxay faa'iidooyinka ugu muhiimsan ee isticmaalka VLANs ?

Shabakadda Aagga Maxalliga ah ee Virtual^{(Virtual Local Area Network)} waa qaybinta nidaamka ee Shabakadda Deegaanka^{(Local Area Network)} . VLAN waxay kuu ogolaaneysaa inaad dhaqangeliso siyaasado amni oo xoogan, waxay ka caawisaa maamulka shabakada iyo xaddidida aagagga baahinta, waxay yaraynaysaa taraafikada baahinta, iwm.

What is VLAN? Why do we use VLANs?

You may or maу not have heard of VLAN (Virtual Local Area Network). It is something that is primarily used in large businesses around the world. If you are interested in opening a business that requires VLANs, you will need to learn more about it. Not only that, if you are interested in CCNA, then you will definitely need to understand what VLAN is all about. But worry not, we have all the information you’ll need in this article.

What is VLAN?

In essence, VLAN is a custom network created from multiple local area networks. If several devices are enabled on multiple networks, they can be combined to create one logical network. The result of this combination becomes a Virtual LAN that is administered in a similar manner to a physical LAN.

Without the presence of a VLAN, any broadcast sent from a single host can reach all network devices instead of the preferred one. This is a problem because it can increase CPU workload, which in turn causes a slow down of your overall network and reduces security to the bare minimum.

Why do we use VLANs?

• Reduction of security risks: When it comes down to reducing security risks, VLAN does this by lowering the number of hosts that can receive copies of frames the switches can flood.
• Improve security: In order to improve security, you can keep hosts with sensitive information on a separate VLAN.
• Create network changes: By configuring a port into the suitable VLAN, you can achieve network changes with ease.
• Increase broadcast domains: If you want to grow the number of broadcast domains while decreasing their size, then your best bet is to use VLAN.
• Improved flexibility: Instead of having to create network designs that group users by physical locations, VLAN makes it possible for a more flexible move to design networks by grouping users in departments.

How to configure VLAN

Now, in terms of conjuring a Virtual Local Area Network, you should know a few things. For example, all ports on a switch are located in VLAN 1. If you want to verify this, please type show vlan command from the IOS enable mode of a switch.

In terms of creating a VLAN and assigning a switch port to that VLAN, there are two key steps you must follow:

First, create a VLAN by using the vlan NUMBER global command

When assigning a switch to a port, you must use the two interface subcommands. The first is, access command, while the second is, switch port access vlan NUMBER command.

The first command is all about specifying that the interface is accessible, while the second is designed to assign the interface to a VLAN.

What are the primary benefits of using VLANs?

A Virtual Local Area Network is a virtual division of systems in a Local Area Network. VLAN allows you to enforce strong security policies, helps with network administration and confinement of broadcast domains, reduces broadcast traffic, etc.
