1. Inzego zitandukanye zakazi:

Igice cya 2kora kuri data ihuza urwego, naIgice cya 3kora kumurongo.Igice cya 3 cyahinduwe ntabwo kigera gusa kumuvuduko wihuse wo kohereza amakuru yamapaki, ariko kandi kigera kubikorwa byiza byurusobe ukurikije imiterere y'urusobe rutandukanye.

2. Ihame riratandukanye:

Ihame rya layer 2 switch ni uko mugihe uhindura yakiriye paki yamakuru kuva ku cyambu runaka, izabanza gusoma inkomoko ya MAC muri paki, hanyuma usome aho MAC igana muri paki, hanyuma urebe hejuru yicyambu muri imbonerahamwe ya aderesi., niba hari icyambu gihuye nicyerekezo cya MAC cyerekanwe kumeza, kora paki yamakuru kuri port.Ihame rya Layeri 3 ihinduka iroroshye, ni ukuvuga inzira imwe ihinduranya inshuro nyinshi.Muri rusange, niyo nzira yambere-yerekeza-aho yerekeza.Inkomoko aho igana irashobora guhanahana vuba.

3. Imirimo itandukanye:

Ihinduka rya Layeri 2 rishingiye ku kwinjira kwa aderesi ya MAC, gusa ryohereza amakuru gusa, kandi ntirishobora kugenwa na aderesi ya IP, mugihe Layeri 3 ihuza tekinoroji yo guhinduranya Layeri 2 hamwe nigikorwa cyo kohereza Layeri 3, bivuze ko icyerekezo cya Layeri 3 ari bishingiye kuri Layeri ya 2.Imikorere ya routing yongeweho hejuru, hamwe na IP adresse ya vlans zitandukanye zirashobora gushyirwaho, kandi itumanaho hagati ya vlans rishobora kugerwaho binyuze mumirongo itatu.

4. Porogaramu zitandukanye:

Igice cya 2 cyahinduwe gikoreshwa cyane cyane kumurongo winjira murwego no guteranya igiteranyo, mugihe Layeri 3 yahinduwe ikoreshwa cyane murwego rwibanze rwurusobe, ariko hariho numubare muto wa Layeri 3 yahinduwe ikoreshwa murwego rwo guteranya.

5. Porotokole ishyigikiwe iratandukanye:

Igice cya 2 cyahinduwe gishyigikira urwego rwumubiri hamwe namakuru ahuza amakuru protocole, nka Ethernet yahinduwe na Layeri 2.HUB ifite imirimo isa, mugihe Layeri 3 ihindura ishyigikira urwego rwumubiri, guhuza amakuru hamwe na protocole y'urusobe.
