Izikhumulo zokushintsha zisebenza njengamaphuzu okubaluleka okuxhuma kwingqalasizinda yenethiwekhi, okwenza amadivayisi amaningi akwazi ukuxhumana ngaphakathi kwenethiwekhi yendawo. Lezi interface ngokomzimba, ngokuvamile ezitholakala on inethiwekhi switch, lula ukudluliswa kwedatha phakathi amadivayisi axhunyiwe ngokusebenzisa ethernet izintambo. Izikhumulo zesimanje zokushintsha zisekela isivinini esihlukahlukene, kusukela ku-10/100 Mbps wendabuko kuya ku-10 Gbps ethuthukisiwe noma ngaphezulu, ukuhlangabezana nezidingo ezahlukene zenethiwekhi. Zinezici zokuxhumana ngokuzenzakalelayo ukuze kunqunywe isivinini sokuxhuma esiphezulu kanye nezilungiselelo ze-duplex ngokuzenzakalelayo. Izimbobo eziningi zokushintsha zine-LED yokuxilonga eyakhelwe ngaphakathi ekhombisa isimo sokuxhuma, isivinini, nomsebenzi. Zisekela ukusebenza kwe-Power over Ethernet (PoE), okuvumela amadivayisi axhunyiwe ukuthi athole amandla ngekhebula elifanayo elisetshenziselwa ukudluliswa kwedatha. Izikhumulo zokushintsha zisebenzisa ukufakwa kwamathegi e-VLAN, okwenza kube nokwakheka kwenethiwekhi nokuphepha okuthuthukisiwe. Zinezinhlelo zokuthola nokulungisa amaphutha ukuze kugcinwe idatha iphephile ngesikhathi sokudluliswa. Ukwakhiwa ngokomzimba kuhlanganisa izixhumi eziqinile ze-RJ-45 ezenzelwe ukusetshenziswa kaningi nokuthembeka kwesikhathi eside. Amamodeli athuthukile asekela izici ezifana nokubuyiselwa kwamatheku okuqapha inethiwekhi kanye nezilungiselelo ze-Quality of Service (QoS) zokubeka phambili ithrafikhi.

Imicabho ye-Switch iwinike amanye amathintana okwenza kuba ngokungafaniyo kumaqondo ongenayo. Iziphumene ukusebenza okuphelele kumathina ngayinye akuxhunywe, ukuze kube nemiphumela embalwa noma yini inkonzo yenkqubo. Imfundo ye-auto-sensing ayikhuthaze ukulungisa ngendlela yokubangela, ukwenza kuba ngokufanelekileyo kubasebenzisi abancinci nebazenzela inkqubo. Ukuthiwa kwe-Power over Ethernet kuphula izindleko zokufaka nezinkinga ngokuthiwa kwebaleka ukudinga kwemicabho efanayo. Imicabho ye-switch ziwinike inkqubo yokwakha ngokusheshayo, ukuvumela izinkampani ukuthi zibekwe njengoba kudingeka ngaphandle kokugcina phansi kakhulu. Inkxotho ye-VLANs iphatha inkqubo yokusekela nokuphathiwa ngokwenza ukunciphisa inkqubo ngendlela ethile. Izici ezifakiweyo zokuhlola kudala ukulungisa nezinkinga futhi kuphule isikhathi esingakanani sokusebenta inkqubo. Ubukhona bokwesekela be-imicabho ye-switch ezeitshwa kubona ukuthi kusebenza ngemva elizayo, ukuthiwa kwezindleko zokubuyisa. Izici ezithuthukiswayo ze-QoS ziphumene ukuthiwa kwezindleko, ukuthiwa izici ebalulekileyo zenziwe ukuthi ziphumene. Ukuthiwa kwezimboniso ezindala zenkqubo zokuxhumana kuphatha izindleko zami ekwenzelwe while kuvumela ukuthi kubuyekezwe ngemva. Isisekelo se-RJ-45 esivumelwanayo siphumelela ukuthiwa kunezinhlobo zezinto zokuxhumana. Ukusebenza okuphezulu kolawulo kwezindleko kuthiwa kwezindleko zokusebenza.

Imiboniso Emingiweyo Yeqhoboshelo Lomkhawulo

Imikhawulo yeshitshi yokwendela ihlanganisa imiboniso yeqhoboshelo engaphezulu engavumela ukungcola kwenkampani nezinombolo. Imehluko yeqhoboshelo lomkhawulo ivumela abasebenzisi ukulima inombolo ye-MAC ebalulekileyo engavumeli ukuxhumana kwamadivayisi angahambi. Imisebenzi yokudla izingxenye zokugcina izinto ezilandelwa ngokushesha, izinto ezilandelayo nezinombolo ezingafanele zenze ukuba inkampani ingapheloni. Ukusebenza kwegesi le-MAC kungeza isimo esinguquko eqhoboshelo ngokuvumela ukufinyelela lomkhawulo kusabo sobuchwephesha. Ukusebenza kwe-802.1X kuvumela ukuthi abasebenzisi abangena kuphela enkampanini ngemikhawulo yeshitshi. Le miboniso yeqhoboshelo iyasebenza ngokuhlanganisa ukwakha isigaba esiphakeme kakhulu ngokuphepha izinkinga zenkampani futhi kuyagcina ukusebenzwa ngokulula kubasebenzisi abatholakele.

Umsamo Wokuhlola Ukudlulisana

Imicabho ye-Switch engenayo i-PoE inikeza izici zokuphatha amandla okwenza ukusebenzela kahle kwezimali neendawo. Lo mbhaliso wamanqina wezixhobo ezisetyenzisiweyo ubala ngokuzenzekelayo iindlela zokunika amandla. Ukugcinwa kwamandla kunikeza ukunika amandla ngexesha elithile okanye ngokwemeko yophatha, ukuncipisa isebenza samandla xa akasebenzi. Ubalo obudingaka lwamandla lune nkcazelo encinane malunga neseka lena lomandla ngasinye incoko, ekuvumela ukuphatha kahle kwezixhobo. Iinkqubo eziphambene ne-PoE+ kunye ne-PoE++ zinikeza amandla angama-90W ngasinye incoko kwiizixhobo ezidinga ngandleke. Isiqinisekiso sendawo sokugcinwa kuzixhobo ukunceda kwiindawo ezisetyenzisiweyo nangona kunikezwa amandla ngendawo.

Ukugcina kweNkqubo Eningiweyo

Izithuba le-switch zinamathela okuquka ukulandwa kwezinjini zokusebenza nezimo zokunethiwe. Ukuhlolwa ngokwesikhashana kwethu kubonisa izinkomba kanye nokuthuthukisa ukucushnelwa kwenethiwekhi. Indawo yokukopisha izithuba ikuvumela ukulandwa okujwayele kwenethiwekhi ngekuphazamisekileyo. Ukuhlolwa kwenani lokusetshenziswa kwebandwidth kubonisela abasebenzisa inkimbinkimbi nezinkinga ezingavamile kulethwe kusipho sezinjini. Ukuxhumeka nenethiwekhi yezokudala ukugcina neyonke i-switch ports. Izisombululo zokuhlola ezinhle kubonisela kakhulu futhi ukuthola izinkinga zokuxhumeka, ukunciphisa isikhathi sokulungisa nekuqinisekisa ukusebenza kwenethiwekhi. Kuhlanganisiwa namanje amaphesenti wezinto esekelwe kungenxa yokuthonga kanye nokuthuthukisa inethiwekhi yezokudala.
