Iimpawu eziphambili

S5456XC umaleko-3 iswitshi kunye 48 x 25GE (SFP +) kunye 8 x 100GE (QSFP28) imisebenzi.Sisizukulwana esilandelayo sokufikelela ngokukrelekrele ukutshintshela uthungelwano lwabahlali benkampani kunye nothungelwano lwamashishini.Umsebenzi wesoftware wemveliso utyebile kakhulu, inkxaso yomzila we-static IPv4 / IPv6, umthamo wokutshintshiselana, inkxaso eyomeleleyo kunye nezinzileyo ye-RIP/OSPF/RIPng/OSPFv3/PIM yemigaqo yomzila, kunye nezinye iimpawu.I-bandwidth yokudlulisa kunye nekhono lokudlulisa likhulu, lihlangabezana neemfuno zamaziko edatha kwiinethiwekhi eziphambili kunye neenethiwekhi ze-backbone.

FAQ

I-Q1: Ngaba ungandixelela malunga nexesha lakho lokuhlawula?

A: Ukuze iisampuli, 100% intlawulo kwangaphambili.Kwi-odolo yobuninzi, i-T / T, i-30% yentlawulo yangaphambili, i-70% ibhalansi ngaphambi kokuthunyelwa.

I-Q2: Linjani ixesha lakho lokuhambisa?

A: 30-45days, ukuba ukwenza ngokwezifiso kwakho kakhulu, kuya kuthatha ixesha elide.

I-Q3: Ngaba ii-ONT / OLTs zakho zinokuhambelana nemveliso yomntu wesithathu?

A: Ewe, ii-ONT/OLTs zethu ziyahambelana nemveliso yomntu wesithathu phantsi kweprotocol eqhelekileyo.

I-Q4: Lide kangakanani ixesha lakho lewaranti?

A: unyaka omnye.

Q5: Uthini umahluko phakathi kwe-EPON GPON OLT kunye ne-XGSPON OLT?

Umahluko omkhulu kukuba iXGSPON OLT ixhasa iGPON/XGPON/XGSPON, iSpeed ​​Speed.

I-Q6: Ziziphi iindlela zokuhlawula ezamkelweyo zenkampani yakho?

Kwisampulu, 100% intlawulo kwangaphambili.Ukuze batch oda, T / T, 30% idiphozithi, 70% ibhalansi phambi kokunikezelwa.

I-Q7: Ngaba inkampani yakho ine-brand yayo?

Ewe, uphawu lwenkampani yethu yiLimee.A Layer 3 switch luhlobo lokutshintsha kwenethiwekhi olusebenza kumaleko womnatha wemodeli yeOSI.Oku kuthetha ukuba inamandla okwenza izigqibo zomzila ngokusekelwe kwiidilesi ze-IP, njenge-router.Utshintsho lweLayer 3 luqhele ukusetyenziswa kuthungelwano lwamashishini ukudibanisa ii-subnets ezahlukeneyo kwaye wenze izigqibo malunga nokuba uthumela phi i-traffic.

Ke, yintoni kanye kanye iSwitshi yeLayer 3 kwaye yahluke njani kuLuhlu lwesi-2 lokutshintsha?I-Layer 2 switch isebenza kwi-data link layer ye-OSI imodeli kwaye yenza izigqibo zokudlulisa ngokusekelwe kwiidilesi ze-MAC.Ngelixa isebenza ngokufanelekileyo ekugqithiseni i-traffic ngaphakathi kwe-subnet enye, ayinakho ukukwazi ukwenza izigqibo zendlela yendlela yokuya kwii-subnets ezahlukeneyo.Apha kulapho iswitshi yeLayer 3 ingena khona.

Utshintsho lweLayer 3 ludibanisa ukusebenza koLuhlu lwe-2 lwemveli kunye nobuchule bokuhambisa umzila.Iyakwazi ukwenza ii-LANs ezibonakalayo (ii-VLAN) kunye ne-traffic yendlela phakathi kwazo, kunye nokwenza izigqibo malunga neyona ndlela ingcono ye-traffic ukuba ithathe inethiwekhi.Oku kuyenza ibe sisixhobo esinamandla sokulawula kunye nokwenza ngcono itrafikhi yenethiwekhi kwiinethiwekhi ezinkulu, ezinzima.

Enye yeenzuzo eziphambili zokusebenzisa iLayer 3 iswitshi kukukwazi kwayo ukuphucula ukusebenza kwenethiwekhi.Ngokukhuphela ezinye zemisebenzi yomzila ukusuka kwi-router engundoqo ukuya kwi-Layer 3 switch, i-traffic traffic inokusasazwa ngokufanelekileyo, ekhokelela kunxibelelwano olukhawulezayo noluthembekileyo phakathi kwezixhobo kwinethiwekhi.

Ngokubanzi, iLayer 3 switch iyi-asethi enexabiso kwimibutho enezidingo zothungelwano ezinzima.Ikhono layo lokudibanisa imisebenzi yokutshintsha kunye ne-router yenza kube yinto ebalulekileyo yokulawula kunye nokuphucula i-traffic network.Njengoko amashishini eqhubeka ethembela kwizisombululo zothungelwano ezomeleleyo nezisebenzayo, iiswitshi zeLayer 3 ziya kuqhubeka zidlala indima ebalulekileyo ekuqinisekiseni ukuba idatha ihamba ngokungenamthungo nangokuthembekileyo kuyo yonke inethiwekhi.
