Kodi Layer 3 Switch ndi chiyani?,
,
S5456XC ndi masinthidwe osanjikiza-3 okhala ndi 48 x 25GE(SFP+) ndi 8 x 100GE(QSFP28) ntchito.Ndi m'badwo wotsatira wolowera mwanzeru wosinthira maukonde okhala ndi ma network ndi mabizinesi.Ntchito yamapulogalamu azinthuzo ndi yolemera kwambiri, kuthandizira njira zokhazikika IPv4 / IPv6, mphamvu yosinthira, thandizo lamphamvu komanso lokhazikika RIP/OSPF/RIPng/OSPFv3/PIM routing protocols, ndi zina.Kutumiza kwa bandwidth ndi kupititsa patsogolo ndikokulirapo, kukwaniritsa zosowa za malo opangira deta pamaneti oyambira ndi maukonde amsana.
Q1: Kodi mungandiuze za nthawi yanu yolipira?
A: Kwa zitsanzo, 100% malipiro pasadakhale.Pakuyitanitsa zambiri, T / T, 30% kulipira pasadakhale, 70% ndalama musanatumize.
Q2: Kodi nthawi yanu yobweretsera ili bwanji?
A: 30-45days, ngati makonda anu kwambiri, zitenga nthawi yaitali.
Q3: Kodi ma ONT / OLTs anu angagwirizane ndi zinthu za chipani chachitatu?
A: Inde, ma ONTs/OLT athu amagwirizana ndi zinthu zina zomwe zili pansi pa protocol yokhazikika.
Q4: Kodi nthawi yanu ya chitsimikizo imakhala yayitali bwanji?
A: 1 chaka.
Q5: Kodi pali kusiyana kotani pakati pa EPON GPON OLT ndi XGSPON OLT?
Kusiyana kwakukulu ndikuti XGSPON OLT imathandizira GPON/XGPON/XGSPON, Kuthamanga Kwambiri.
Q6: Kodi njira zolipirira zovomerezeka za kampani yanu ndi ziti?
Kwa zitsanzo, 100% kulipira pasadakhale.Pakuti mtanda dongosolo, T / T, 30% gawo, 70% bwino pamaso yobereka.
Q7: Kodi kampani yanu ili ndi mtundu wake?
Inde, mtundu wa kampani yathu ndi Limee.A Layer 3 switch ndi mtundu wa switch ya netiweki yomwe imagwira ntchito pa netiweki ya mtundu wa OSI.Izi zikutanthauza kuti ili ndi kuthekera kopanga zisankho zamayendedwe potengera ma adilesi a IP, monga rauta.Ma switch a Layer 3 amagwiritsidwa ntchito kwambiri pama network abizinesi kuti alumikizane ndi ma subnet osiyanasiyana ndikupanga zisankho za komwe angatumize magalimoto.
Ndiye, switch ya Layer 3 ndi chiyani kwenikweni ndipo imasiyana bwanji ndi switch yachikhalidwe ya Layer 2?Kusintha kwa Layer 2 kumagwira ntchito pagawo la data la mtundu wa OSI ndikupanga zisankho zotumizira kutengera ma adilesi a MAC.Ngakhale ndiyothandiza pakutumiza magalimoto mkati mwa subnet imodzi, ilibe kuthekera kopanga zisankho zamagalimoto opita kumagulu osiyanasiyana.Apa ndipamene switch ya Layer 3 imabwera.
Kusintha kwa Layer 3 kumaphatikiza magwiridwe antchito amtundu wamtundu wa Layer 2 ndi kuthekera kwa mayendedwe a rauta.Imatha kupanga ma LAN (VLANs) ndikuyendetsa magalimoto pakati pawo, komanso kupanga zisankho zanjira yabwino kwambiri yoti magalimoto adutse pamaneti.Izi zimapangitsa kukhala chida champhamvu chowongolera ndikuwongolera kuchuluka kwa magalimoto pamanetiweki akuluakulu, ovuta.
Ubwino umodzi wogwiritsa ntchito switch ya Layer 3 ndikutha kuwongolera magwiridwe antchito a netiweki.Potsitsa zina mwazomwe zimayendera kuchokera pa core router kupita ku Layer 3 switch, kuchuluka kwa magalimoto pamaneti kumatha kugawidwa bwino, zomwe zimapangitsa kulumikizana mwachangu komanso kodalirika pakati pa zida pamaneti.
Ponseponse, switch ya Layer 3 ndi chinthu chofunikira kwambiri m'mabungwe omwe ali ndi zosowa zovuta zapaintaneti.Kutha kwake kuphatikiza ntchito za switch ndi rauta kumapangitsa kuti ikhale gawo lofunikira pakuwongolera ndikuwongolera kuchuluka kwa magalimoto pamaneti.Pomwe mabizinesi akupitilira kudalira njira zolumikizirana komanso zodalirika, masiwichi a Layer 3 apitiliza kugwira ntchito yofunika kwambiri pakuwonetsetsa kuti deta ikuyenda bwino komanso modalirika pamanetiweki onse.
