iswitch enenqanawa SFP

Isithwici esinezindawo zokuhlanjwa kwe-SFP sikhomba isisombululo sophuwo olunye lwesikoleni lapho kudluliselwe izindawo eziphumelelayo nezindawo zokuhlanjwa ze-Small Form-factor Pluggable. Lezi zinhlobo zisebenza njengokwamukelwa kwesivivinyo esisha sangaphambili, zinikeza amadwayo okuxhumana ngemali nezibonisa ukuxhumana ngokushintsha kwegolo lokuthi yazo. Le sihlalo linemigqa ye-RJ45 engokuthi yezimali ezijwayelekile futhi linemigqa ye-SFP eyathola izithwici ezihlinzekayo. Lokhu kunesifaniso sokubili kuvumela abasebenzisi besivivinyo ukulandela ukusebenza kwesivivinyo ngokuxhumana ngegolo lapho kuzinzile ukuthi kuyasekelwe emalinganeni ewasetyweni. Izindawo zokuhlanjwa ze-SFP zisinetha amathayiphi amaningi wemoduli yogolo, kuvumela ukuxhumana okufushane noma okude, nendawo yokohshana enkulu-enkulu ibe phakathi kwe-1Gbps kanye ne-10Gbps. Le sihlalo iyagqoka kakhulu kuzindlela ezidinga ukuxhumana ngokushintsha komgca womlando, zinikeza ukuthi igolo nezimali ziphumelelane ngokuphelele. Inqolobane yesikhala sokuthiwa kwezimoduli ze-SFP ivumela ukuguqula kwe-sivivinyo ngokusheshayo ngenkathi ayiphansi isistimu, futhi nezinto ezinhle njengekhwamkhakha kwe-VLAN, i-QoS, nekulawula ukuxhumana okungcono kuhlanga isivivinyo singcono. Umqondo wesihlalo futhi kunezimo ezinkulu ezisetshenziswa ukugcina ukuxhumana okuphelele kuzomgqa wonke, lokhu kuvumela ukuthi usebenze kahle kuzindlela zokusebenzela nezindatshana zamanje.

Ukushintsha ngezingcingo ze-SFP kunikeza izinzuzo eziningi ezicindezelayo ezenza kube ingxenye ebalulekile yesakhiwo senethiwekhi yesimanje. Okokuqala, ukuguquguquka kwayo ekukhetheni uhlobo lwedijithali kuvumela izinhlangano ukuthi zisebenzise kokubili ukuxhumana kwe-fiber ne-copper ngaphakathi kwedivayisi eyodwa, kunciphisa isidingo sokushintsha okuningi nokwenza lula ukwakheka kwenethiwekhi. Imvelo eshisayo-shintshable of SFP amamojuli kwenza ukuzivumelanisa ngokushesha nezidingo inethiwekhi eziguqukayo ngaphandle isikhathi sokuphumula, ngesikhathi esifanayo lula ukugcinwa lula kanye nokuthuthukiswa. Ukusebenza kahle kwezindleko kungenye inzuzo ebalulekile, njengoba izinhlangano zingaqala ngezidingo eziyisisekelo zokuxhuma futhi zikhulise ngokungeza amamojula afanele we-SFP njengoba izidingo zikhula. Ukusekela amabanga ahlukahlukene okudlulisa ngamamojula ahlukene e-SFP kwenza kube nokwenzeka ukwandisa inethiwekhi ngaphandle kokuthi kushintshwe yonke ingqalasizinda yeswishi. Ukuthembeka okuthuthukisiwe kuvela ekhonweni lokusebenzisa ukuxhumana kwe-fiber ezindaweni ezizwela umsindo noma amabanga amade, kuyilapho kugcinwa ukuxhumana kwethusi kwamadivayisi endawo. Izishintshi ngokuvamile zinamakhono aphezulu okuphatha, kufaka phakathi ukucushwa okukude, ukuqapha, namathuluzi okuxazulula izinkinga, okunciphisa izindleko zokusebenza. Ukusebenza kahle kwamandla kukhuliswa ngokusebenzisa ukufakwa kwamatheku okukhethiwe kanye nezici zokuphathwa kwamandla okuhlakaniphile. Ukuphepha kuthuthukiswa ngokusebenzisa amakhono okuqinisekisa nokufaka ikhodi asekelwe ezingosini, okuvikela ukudluliswa kwedatha ebucayi. Ifomethi ye-SFP ehlelekile iqinisekisa ukuhambisana namamojula avela kubakhiqizi abahlukahlukene, inikeza ukuguquguquka ekukhetheni abathengisi nasekuthuthukiseni izindleko. Ngaphezu kwalokho, lezi zinguquko zivame ukusekela izici ezithuthukile ezifana nokuhlanganiswa kwesixhumanisi, i-spanning tree protocol, kanye nekhwalithi yesevisi, okwenza kube nokwakhiwa kwenethiwekhi eyinkimbinkimbi nokusebenza kahle kwezicelo ezibalulekile.

Ukuvumelana Nezimo Okuyingqayizivele Kokuxhuma

Iswishi enamachweba e-SFP igqama ekuhlinzekeni ukuvumelana nezimo okungenakulinganiswa kokuxhuma kwenethiwekhi ngokusebenzisa ukwakheka kwayo kwechweba le-hybrid. Lesi sici sivumela abaphathi benethiwekhi ukuba bahlanganise futhi bafanise izinhlobo ezahlukene zokuxhuma ngokusekelwe ezidingweni ezithile. Ikhono lokusebenzisa amamojula ahlukahlukene e-SFP lenza kube nokwesekwa kwezinhlobo ezahlukene ze-fiber (imodi eyodwa noma imodi eminingi), ubude bamaza, namabanga wokudlulisa, konke ngaphakathi kwepulatifomu efanayo yokushintsha. Lokhu kuguquguquka kufinyelela ezinhlotsheni zejubane, okusekela ukuxhumana kusuka ku-100Mbps kuya ku-10Gbps, kuye ngokuthi iyiphi imodyuli ye-SFP efakiwe. Abaphathi benethiwekhi bangathuthukisa kalula amachweba ngamanye ngokumane bashintshisane ngamamojula, okwenza ukushintshwa kube okuqinile esikhathini esizayo futhi kuvumelane nezidingo zenethiwekhi eziguqukayo. Imvelo eshisayo-shintshable SFP amachweba kuqinisekisa zero isikhathi sokuphumula ngesikhathi ngcono noma ukugcinwa.

Imikembo Yesikhathi Esikhulu Noqobo Lokuqala

Ukusebenza kweqoqa leswitches enenani le-SFP kunceda kakhulu ukubona nokuphatha izinto ebalulekileyo kumisebenzi wenethiwekhi yesikhathi seshukela. Abasebenzisi bakwazi ukufinyelela kwiimibiko yezikhala, ngokuchaza uhlobo lwenethiwekhi, ubungu bazo, neemeko zokuxhumana kwazo zazo zombini izikhala zemali nezikhala zefayibha. Lo msebenzi ubukelwa ngemikembo ebalulekileyo ngokujonga uhlobo lwenethiwekhi (port mirroring), i-SNMP lokugcina nethiwekhi, neemikembo ezithuthukisweyo zokuphatha ubungu benthongo (QoS). Iimikembo zokuphepha kuyindlela yokuthiwa kwekhala, ukuchonga ikheli le-MAC, nokuphatha ukugcinwa kwezulu.

Imisho yokwenza izindleko zokusebenza ngendlela efanelekileyo

Imenyu enenani ngemathithini akawotwe SFP iyabelana ngendlela ethuthelwe kakhulu ukuthi ikhwekhwele yamanje. Iindlela zokusebenzela kwaqala ngokubeka imenyu ngokuxhuma kwamadoda angaphandle kokwenzeka futhi ngokwengeza imikhawulo yokuxhumana ngamafayela ngezinyathelo ze-SFP uma kudingekile, ukungena kwezimali ezinkulu ngokuqala. Le ndlela eyinhloko iyavumela ukwahlulwa okuhle kwezimali, nangokuthi kungenzeka ukuvuselela imathithi ngokushintsho kwebandwidth noma izindlela zokuxhumana. Ifomethi ye-SFP esivumelwanayo iyagcina ukuthi ikhuthe imikhawulo yeziphakeli eziningi, okwenza umthamo othuthelwe kakhulu. Izindleko zokugcina kude ngemuva kuzokwenzeka ukunciphisa izindleko zokulungiswa ngokunqatfatsa uhlelo lwenkxowa futhi ukusetshenziswa futhi imikhawulo ye-SFP emanye amaphothinki.
