Munyika yenetworking, switch inoita semusana, inonyatso fambisa data pakiti kune kwavanoda kuenda. Kunzwisisa izvo zvakakosha zvekuchinja mashandiro kwakakosha kuti ubate kuomarara kweazvino network yezvivakwa.
Chaizvoizvo, switch inoshanda senge multiport mudziyo unoshanda pane data link layer yeOSI modhi. Kusiyana nemahubhu, ayo anotepfenyura data zvisina tsarukano kune ese akabatana zvishandiso, switch inogona nehungwaru kuendesa data kune chaiyo mudziyo kwainoenda, ichivandudza network nekuchengetedza.
Iko kushanda kweiyo switch kunoenderana nezvakawanda zvakakosha zvikamu uye maitiro:
MAC kero kudzidza:
Iyo switch inochengetedza tafura yekero yeMAC inobatanidza kero dzeMAC nemachiteshi anowirirana anodzidzidza. Kana furemu yedata yasvika pachiteshi chekuchinja, switch inotarisa kwainobva MAC kero uye inogadzirisa tafura yayo zvinoenderana. Iyi nzira inoita kuti shanduko iite sarudzo dzine ruzivo pamusoro pekuendesa mberi mafaremu anotevera.
Pamberi
Kana switch ikangodzidza kero yeMAC yechishandiso chakabatana pachiteshi chayo, inogona kupfuudza mafuremu zvakanaka. Kana furemu yasvika, switch inobvunza tafura yekero yeMAC kuti ione nzvimbo yakakodzera inobuda kunze kwekero yeMAC. Iyo furemu inozoendeswa kune iyo chiteshi chete, ichideredza zvisina basa traffic pane network.
Nhepfenyuro uye isingazivikanwe mafashama eunicast:
Kana iyo switch ikagamuchira furemu ine kwainoenda MAC kero isingawanikwe mune yayo MAC kero tafura, kana iyo furemu yakarongerwa kero yekutepfenyura, switch inoshandisa mafashama. Inoendesa mafuremu kune ese zviteshi kunze kwechiteshi panotambirwa furemu, ichiva nechokwadi chekuti furemu inosvika kwainoda kuenda.
Kero Resolution Protocol (ARP):
Kuchinja kunoita basa rakakosha mukufambisa maitiro eARP mukati metiweki. Kana mudziyo uchinge wada kuona iyo MAC kero inoenderana neimwe IP kero, inotepfenyura chikumbiro cheARP. Iyo switch inoendesa mberi chikumbiro kune ese madoko kunze kwechiteshi pakagamuchirwa chikumbiro, ichibvumira mudziyo une IP kero yakakumbirwa kuti ipindure zvakananga.
VLANs uye hunde:
Virtual LANs (VLANs) inobvumira switch kuti igovane network munzvimbo dzakasiyana dzekutepfenyura, kuvandudza mashandiro nekuchengetedza. Trunking inogonesa switch kuti itakure traffic kubva kune akawanda maVLAN pane imwechete yemuviri link, ichiwedzera kuchinjika mukugadzira network uye kumisikidzwa.
Muchidimbu, ma switch anoumba ibwe repakona remazuva ano network network, kufambisa kutaurirana kwakanaka uye kwakachengeteka pakati pemidziyo. Nekutarisisa mukati mekuomesesa kwekushanda kwekuchinja, vatariri venetiweki vanogona kukwidziridza mashandiro, kuwedzera kuchengetedzeka, uye kuve nechokwadi chekuyerera kwe data kunetiweki.
Toda inyanzvi mukugadzira switch uye kugadzirisa network yekuvaka kumabhizinesi.
