1. Heerarka shaqo ee kala duwan:

Lakabka 2 shidoka shaqeeya lakabka isku xirka xogta, iyoLakabka 3 wareegyadaka shaqee lakabka shabakada.Lakabka 3 ma aha oo kaliya inuu gaaro gudbinta xawaaraha sare ee xirmooyinka xogta, laakiin sidoo kale waxay gaaraan waxqabadka shabakada ugu fiican iyadoo loo eegayo shuruudaha shabakadaha kala duwan.

2. Mabda'a waa ka duwan yahay:

Mabda'a lakabka 2 ee beddelka ayaa ah in marka shixnaduhu uu ka helo xirmo xog ah deked gaar ah, uu marka hore akhrin doono ciwaanka MAC ee baakidhka, ka dibna akhri ciwaanka MAC meesha uu ku jiro ee baakidhka, oo uu eego dekedda u dhiganta miiska cinwaanka., haddii ay jirto deked u dhiganta cinwaanka MAC ee miiska ku yaal, si toos ah ugu koobi baakidhka xogta dekeddan.Mabda'a beddelka lakabka 3 waa mid fudud, taas oo ah, hal waddo ayaa la beddelaa dhowr jeer.Guud ahaan marka loo eego, waa dariiqa ugu horreeya ee isha loo tago.Ilaha meesha loo socdo si dhakhso ah ayaa loo beddeli karaa.

3. Shaqooyin kala duwan:

Lakabka 2 wuxuu ku salaysan yahay helitaanka cinwaanka MAC, kaliya wuxuu gudbiyaa xogta, lagumana hagaajin karo ciwaanka IP-ga, halka lakabka 3 uu ku darayo tignoolajiyada wareejinta lakabka 2 iyo shaqada gudbinta lakabka 3, taas oo macnaheedu yahay in lakabka 3 uu yahay wareejinta. ku salaysan lakabka 2 beddelka.Shaqada dariiqa waxaa lagu daraa kuwa kore, iyo ciwaanada IP-ga ee vlans kala duwan waa la habeyn karaa, xiriirka ka dhexeeya vlans waxaa lagu xaqiijin karaa iyada oo loo marayo saddex lakab.

4. Codsiyo kala duwan:

Lakabka 2 furayaasha inta badan waxaa loo isticmaalaa lakabka gelitaanka shabakada iyo lakabka isku-darka, halka lakabka 3 dareemaha inta badan lagu isticmaalo lakabka xudunta u ah shabakada, laakiin waxa kale oo jira tiro yar oo lakabka 3 ah oo loo isticmaalo lakabka isku-darka.

5. Nidaamyada la taageeray waa kala duwan yihiin:

Lakabka 2 wuxuu taageeraa lakabka jirka iyo borotokoolka lakabka xogta, sida furayaasha Ethernet iyo dareemada lakabka 2.HUB-gu waxa uu leeyahay hawlo la mid ah, halka lakabka 3 dareemaha uu taageerayo lakabka jidhka, lakabka isku xidhka xogta iyo borotokoolka lakabka shabakada.
