1. Matanho ekushanda akasiyana:

Layer 2 switchshanda pane data link layer, uyeLayer 3 switchshanda pane network layer. Layer 3 switch haingogone chete kumhanyisa-kumhanyisa kutumira kwepakeji yedata, asi zvakare inowana yakakwana yetiweki kuita zvinoenderana neakasiyana mamiriro etiweki.

2. Nheyo yacho yakasiyana:

Nheyo yeaya 2 switch ndeyekuti kana switch yagamuchira pakiti yedata kubva kune imwe chiteshi, inotanga yaverenga kwainobva MAC kero mupaketi, yobva yaverenga kero yeMAC yepakiti, uye tarisa kumusoro inoenderana chiteshi mukati. tafura yekero. , kana paine chiteshi chinoenderana nekwainoenda MAC kero patafura, kopira data packet zvakananga kuchiteshi ichi. Nheyo yeLayer 3 switch iri nyore, kureva kuti, nzira imwe inotsinhaniswa kakawanda. Kazhinji kutaura, ndiyo nzira yekutanga-yekuenda-kuenda. Kunobva kwaunoenda kunogona kuchinjana nekukurumidza.

3. Mabasa akasiyana:

Iyo Layer 2 switch yakavakirwa paMAC kero yekuwana, inongoendesa mberi data, uye haigone kugadziridzwa ne IP kero, nepo Layer 3 switch ichibatanidza iyo Layer 2 switching tekinoroji neLayer 3 kutumira basa, zvinoreva kuti Layer 3 switch iri. zvichibva paLayer 2 switch. Basa rekufambisa rinowedzerwa kune zviri pamusoro, uye IP kero dzevlans dzakasiyana dzinogona kugadzirwa, uye kutaurirana pakati pevlans kunogona kuitika kuburikidza nematatu-layer routing.

4. Zvikumbiro zvakasiyana:

Layer 2 switches inonyanya kushandiswa pane network yekupinda layer uye aggregation layer, nepo Layer 3 switches inonyanya kushandiswa papakati petiweki, asi kune zvakare nhamba diki yeLayer 3 switch inoshandiswa pakuunganidza.

5. Maprotocol anotsigirwa akasiyana:

Layer 2 switch inotsigira dhizaini yemuviri uye data link layer protocol, senge Ethernet switch uye Layer 2 switch. Iyo HUB ine mabasa akafanana, nepo Layer 3 inochinja inotsigira muviri layer, data link layer uye network layer protocol.
