Layer 3 switch yog dab tsi?,
,
S5000 series tag nrho Gigabit nkag + 10G uplink Layer3 hloov, sib xws nrog POE muaj nuj nqi, ua rau kev txhim kho lub zog txuag muaj nuj nqi, yog cov tiam tom ntej ntawm cov ntse nkag mus rau cov neeg nyob hauv lub network thiab kev lag luam network.Nrog kev nplua nuj software ua haujlwm, txheej 3 routing raws tu qauv, kev tswj yooj yim, thiab hloov tau yooj yim, cov khoom tuaj yeem ua tau raws li ntau yam xwm txheej.
Ib txheej thib peb hloov yog ib qho cuab yeej tshwj xeeb siv hauv computer networks.Nws ua ke cov haujlwm ntawm cov keyboards ib txwm siv thiab routers, ua kom muaj ntau yam thiab muaj txiaj ntsig zoo rau kev tswj hwm kev sib txuas hauv network.Tsis zoo li cov txheej txheem ib txwm siv ob lub hloov pauv uas xa cov ntaub ntawv raws li qhov chaw nyob ntawm lub cev (MAC chaw nyob) ntawm cov cuab yeej txuas nrog, cov txheej txheem thib peb kuj tuaj yeem teeb tsa raws li txheej txheej network (IP chaw nyob).Qhov no ua rau kev xa cov ntaub ntawv ntawm lub network ntse dua thiab ua tau zoo dua.
Peb lub tuam txhab muaj ntau tshaj 10 xyoo ntawm R & D kev paub nyob rau hauv Tuam Tshoj txoj kev lag luam kev sib txuas lus thiab muaj ntau yam khoom siv network, nrog rau peb-txheej hloov khoom siv.Peb 3-txheej hloov pauv tuaj nrog ntau yam ntawm cov yam ntxwv thiab muaj peev xwm ua tau raws li qhov xav tau ntawm peb cov neeg siv khoom.Los ntawm kev txhawb nqa rau ntau txoj kev sib txuas lus xws li RIP, OSPF thiab PIM rau Lub Hwj Chim ntawm Ethernet (POE), peb lub tshuab 3 yog tsim los ua kom kev tswj hwm kev sib txuas lus yooj yim dua.
Ntxiv rau cov qauv nta, peb 3-txheej hloov pauv kuj tseem txhawb IPv4 / IPv6 dual raws tu qauv, nws pib siv tshuab pw tsaug zog, pab pawg ua haujlwm qeeb thiab kev tswj hwm kev sib koom ua ke.Cov yam ntxwv siab heev no ua rau peb 3 lub tshuab zoo tagnrho rau cov chav sib tham niaj hnub uas xav tau kev ua haujlwm siab, muaj zog thiab lub zog ua haujlwm.
Tsis tas li ntawd, peb cov 3-txheej hloov pauv muaj ib lossis ob txoj kev xaiv hluav taws xob muab kev rov siv tau thiab kev ntseeg siab rau kev sib txuas lus tseem ceeb.Tsis tas li ntawd, peb cov keyboards tuaj yeem tswj cov ntaub ntawv hloov pauv ceev nrog cov qauv txhawb nqa 1G, 40G, thiab txawm tias 100G nrawm.Qhov no ua rau lawv haum rau ntau yam kev siv web, los ntawm cov lag luam me mus rau cov lag luam loj.
Hauv cov ntsiab lus, Layer 3 hloov yog ib qho cuab yeej muaj txiaj ntsig zoo rau kev ua haujlwm zoo hauv kev sib txuas lus thiab kev tswj hwm.Nrog peb cov kev paub dhau los thiab kev sib txuas lus, peb tau cog lus los muab cov txheej txheem 3-kauj ruam zoo tshaj plaws kom tau raws li cov kev xav tau ntawm lub network niaj hnub no.Txawm hais tias koj xav tau kev hloov pauv yooj yim lossis kev ua haujlwm siab heev, peb cov hloov pauv Series 3 muab cov kev daws teeb meem rau koj cov kev xav tau sib txuas.
