,
Main Features
S5456XC is a layer-3 switch ine 48 x 25GE(SFP+) uye 8 x 100GE(QSFP28) mabasa.Icho chinotevera-chizvarwa chehungwaru yekuwana switch kune inotakura vagari network uye bhizinesi network.Iyo software basa rechigadzirwa rakapfuma kwazvo, static routing inotsigira IPv4 / IPv6, kuchinjanisa huwandu, yakasimba uye yakagadzikana rutsigiro RIP/OSPF/RIPng/OSPFv3 / PIM routing protocol, uye zvimwe zvinhu.Iyo yekufambisa bandwidth uye kugona kwekutumira yakakura, inosangana nezvinodiwa zve data centers pane core network uye backbone network.
FAQ
Q1: Unogona kundiudza nezve nguva yako yekubhadhara?
A: For samples, 100% kubhadhara mberi.Nekuodha kwakawanda, T / T, 30% kubhadhara kwepamberi, 70% chiyero chisati chatumirwa.
Q2: Ndeipi nguva yako yekuendesa?
A: 30-45days, kana maitiro ako akawandisa, zvinotora nguva yakati rebei.
Q3: Ko ONTs/OLTs ako anogona kuenderana nevechitatu-bato zvigadzirwa?
A: Ehe, edu ONTs/OLTs anowirirana nevechitatu bato zvigadzirwa pasi peyakajairika protocol.
Q4: Inguva yakareba sei waranti yako?
A: 1 gore.
Q5: Ndeupi musiyano uripo pakati peEPON GPON OLT neXGSPON OLT?
Musiyano mukuru ndewekuti XGSPON OLT inotsigira GPON/XGPON/XGSPON, Inokurumidza Kumhanya.
Q6: Ndedzipi nzira dzekubhadhara dzakagamuchirwa dzekambani yako?
Yemuenzaniso, 100% kubhadhara mberi.Kune batch kurongeka, T / T, 30% dhipoziti, 70% chiyero pamberi pekusununguka.
Q7: Ko kambani yako ine mhando yayo here?
Hongu, kambani yedu brand iLimee.A Layer 3 switch imhando yetiweki switch inoshanda pane network layer yeOSI modhi.Izvi zvinoreva kuti inokwanisa kuita sarudzo dzekufambisa zvichibva pamakero eIP, senge router.Layer 3 switches inowanzo shandiswa mumabhizinesi network kubatanidza ma subnets akasiyana uye kuita sarudzo dzekuti unoendesa kupi traffic.
Saka, chii chaizvo chinonzi Layer 3 switch uye chinosiyana sei kubva kune yechinyakare Layer 2 switch?A Layer 2 switch inoshanda pane data link layer yeOSI modhi uye inoita sarudzo dzekutumira zvichibva pamakero eMAC.Kunyange ichinyatso kuendesa traffic mukati meimwe subnet, inoshaya kugona kuita sarudzo dzenzira dzetraffic kuenda kune dzakasiyana subnets.Apa ndipo panopinda Layer 3 switch.
Iyo Layer 3 switch inosanganisa mashandiro echinyakare Layer 2 switch neiyo nzira yekugona ye router.Iyo inokwanisa kugadzira chaiwo maLAN (VLANs) uye routing traffic pakati pavo, pamwe nekuita sarudzo nezve yakanakisa nzira yetraffic kutora kuburikidza netiweki.Izvi zvinoita kuti ive chishandiso chine simba chekugadzirisa nekugadzirisa network traffic muhombe, yakaoma network.
Imwe yemabhenefiti akakosha ekushandisa Layer 3 switch kugona kwayo kuvandudza mashandiro etiweki.Nekurodha mamwe emabasa ekufambisa kubva kune yakakosha router kuenda kuLayer 3 switch, network traffic inogona kugovaniswa zvakanyanya, zvichitungamira nekukurumidza uye kwakavimbika kutaurirana pakati pemidziyo pane network.
Pakazere, a Layer 3 switch chinhu chakakosha kumasangano ane zvakaoma network zvinodiwa.Kugona kwayo kusanganisa mabasa ekuchinja uye router kunoita kuti ive chinhu chakakosha chekugadzirisa uye kugadzirisa network traffic.Sezvo mabhizinesi ari kuramba achivimba nemhinduro dzakasimba uye dzinoshanda dzetiweki, Layer 3 switch icharamba ichiita basa rakakosha mukuona kuti data inofamba zvisina musono uye nekuvimbika mukati metiweki yese.
