Tilmaamaha ugu muhiimsan

S5456XC waa lakab-3 wareeg oo leh 48 x 25GE(SFP+) iyo 8 x 100GE(QSFP28).Waa furaha gelitaanka garaadka jiilka xiga ee shabakadaha deganeyaasha iyo shabakadaha ganacsiga.Shaqada softiweerka ee badeecadu aad bay hodan u tahay, taageerada marin habaabinta IPv4/IPv6, awoodda isdhaafsiga, taageerada xooggan oo xasilloon ee RIP/OSPF/RIPng/OSPFv3/PIM borotokoolka marin-u-socodka, iyo astaamo kale.Baaxadda gudbinta iyo awoodda gudbintu waa ballaaran tahay, oo buuxinaysa baahiyaha xarumaha xogta ee shabakadaha asaasiga ah iyo shabakadaha laf dhabarta.

Muunad ahaan, 100% ka hor bixinta.Dalabka Dufcaddii, T/T, 30% deebaaji, 70% baaqi ka hor dhalmada.

Q7: Shirkaddaadu ma leedahay astaan ​​u gaar ah?

Haa, sumadda shirkadeena waa Lime.A Layer 3 switch waa nooc ka mid ah furaha shabkada kaas oo ka shaqeeya lakabka shabakada qaabka OSI.Tani waxay ka dhigan tahay inay awood u leedahay inay sameyso go'aamo ku-meel-gaar ah oo ku saleysan cinwaannada IP-ga, sida router-ka.Lakabka 3 furayaasha ayaa inta badan loo adeegsadaa shabakadaha ganacsiga si loogu xidho shabakado hoosaadyo kala duwan oo loo sameeyo go'aano ku saabsan halka loo gudbiyo taraafikada.

Haddaba, waa maxay dhab ahaan beddelka lakabka 3 iyo sidee uga duwan yahay beddelka lakabka 2 ee dhaqameed?Lakabka 2 wuxuu ku shaqeeyaa lakabka isku xirka xogta ee moodeelka OSI wuxuuna sameeyaa go'aano gudbin ah oo ku salaysan ciwaannada MAC.In kasta oo ay si hufan ugu gudbinayso taraafikada hal subnet, waxa ay ka maqan tahay awoodda ay ku samayso go'aannada ku-wareejinta taraafikada aadaya shabakad-hoosaadyo kala duwan.Halkani waa meesha uu ka soo galo lakabka 3.

Dareemaha lakabka 3 ayaa isku daraa shaqaynta beddelka lakabka 2 ee caadiga ah iyo awoodaha jihaynta ee router.Waxay awood u leedahay inay abuurto LAN-yada casriga ah (VLANs) iyo isku xirka gaadiidka dhexdooda, iyo sidoo kale samaynta go'aannada ku saabsan waddada ugu fiican ee taraafikada loo maro shabakad.Tani waxay ka dhigaysaa qalab awood leh oo lagu maareeyo laguna wanaajiyo taraafikada shabakada ee shabakadaha waaweyn ee adag.

Mid ka mid ah faa'iidooyinka muhiimka ah ee isticmaalka beddelka lakabka 3 waa awoodda uu u leeyahay inuu hagaajiyo waxqabadka shabakadda.Markaad ka dejiso qaar ka mid ah hawlaha dariiqa ee router-ka xudunta u ah beddelka lakabka 3, taraafikada shabakadda waxaa loo qaybin karaa si hufan, taasoo horseedaysa xiriir degdeg ah oo la isku halleyn karo oo ka dhexeeya aaladaha shabakadda.

Guud ahaan, wareejinta lakabka 3 waa hanti qiimo leh oo loogu talagalay ururada leh baahiyaha isku xidhka adag.Awooddeeda isku-darka hawlaha furaha iyo router-ku waxay ka dhigaysaa qayb muhiim u ah maaraynta iyo hagaajinta taraafikada shabakadda.Maaddaama ganacsiyadu ay sii wadaan inay ku tiirsanaadaan xalalka isku xidhka adag oo hufan, Lakabka 3 furayaasha ayaa sii wadi doona inay ciyaaraan door muhiim ah si loo hubiyo in xogtu u socoto si aan kala go 'lahayn oo la isku halleyn karo dhammaan shabakada.
