Muaj cov keyboards tshwj xeeb hauv kev tsim cov kev daws teeb meem kom ua tau raws li qhov yuav tsum tau ua ntawm kev hloov pauv thiab ntau yam kev lag luam ntau lawm, thiab nthuav tawm cov nqi hluav taws xob sib txuas lus sib txuas lus daws teeb meem.Cov keyboards muaj kuj tau muab faib ua ob hom: tswj thiab tsis tswj.Yog li, dab tsi yog qhov txawv ntawm kev tswj kev hloov pauv thiab kev hloov pauv tsis muaj kev tswj hwm, thiab koj yuav xaiv li cas?

Qhov zoo ntawmManaged Industrial Switches
ib.Lub backplane bandwidth yog qhov loj, thiab cov ntaub ntawv sib qhia tus nqi nrawm dua;
b.Lub network tswj kev lag luam hloov kev sib txuas lus yog hloov tau, thiab cov txheej txheem kev sib txuas ntawm cov tes hauj lwm loj, nruab nrab thiab me;
c.Qhov chaw nres nkoj muab tau yooj yim;qhov sib txawv ntawm qhov kev txhawb nqa taw tes VLAN, tus neeg siv khoom tuaj yeem ua tiav qhov kev sib txawv hauv cheeb tsam rau cov kev siv sib txawv, ua haujlwm zoo thiab kev tswj hwm txoj hauv kev ntawm lub network, thiab ntxiv rau kev tawm tsam cua daj cua dub;
d.Cov ntaub ntawv xov xwm ntawm lub network tswj hom kev lag luam hloov pauv muaj cov khoom thauj loj, ib pob ntawv pov tseg me me, thiab qeeb qeeb;
e.Nws tuaj yeem cuam tshuam nrog ob peb Ethernet interface ports rau cov kev pabcuam hauv web;
f.Muaj ARP kev tiv thaiv muaj nuj nqi los txo cov kev dag hauv network ARP;kev koom tes ntawm MAC chaw nyob;
g.Ib qho yooj yim los nthuav thiab txawj ntse, koj tuaj yeem siv cov kev tswj hwm network software los tsim cov kev tswj hwm, thiab koj tuaj yeem mus los ntawm nws tus kheej browsing thiab manipulation.Txhawm rau ua qhov kev tshawb nrhiav ntev, ntxiv rau qhov kev nyab xeeb thiab kev nyab xeeb ntawm lub network.

Disadvantages ntawm Managed Industrial Switches

ib.Me ntsis kim tshaj qhov tsis muaj kev tswj hwm kev lag luam hloov pauv;
b.Kev hloov pauv tsis muaj kev tswj hwm yog qhov nyuaj dua li qhov kev ua haujlwm tiag tiag thiab yuav tsum tau siv cov khoom siv.Qhov no feem ntau zoo dua li lub network tswj kev lag luam hloov, tab sis muaj qee qhov ntev thiab ntev.Lub network tswj kev lag luam hloov pauv muaj lub hauv paus tuab, muaj zog ua haujlwm, thiab kev ntseeg tau zoo.Nws yog haum rau loj thiab nruab nrab-qhov loj me network tej yam ntuj tso ib puag ncig;nws tsis yog kev tswj hwm kev hloov pauv, tus nqi Nws kuj yog tus nqi zoo, thiab siv dav hauv kev tsim cov kev sib txuas me me thiab nruab nrab.

Qhov zoo ntawmunmanaged industrial switches
ib.Tus nqi qis thiab txuag nqi;
b.Tag nrho cov chaw nres nkoj yog tag nrho;
c.Kev tuav haujlwm, hloov tau yooj yim.

Disadvantages ntawm unmanaged industrial keyboards
ib.Unmanaged industrial keyboards muaj kev txwv tsis pub muaj zog thiab tsim nyog rau kev teeb tsa hauv tsev lossis kev sib txuas me me thiab nruab nrab;
b.Tsis muaj kev txhawb nqa rau point ARP tiv thaiv, MAC chaw nyob koom nrog, thiab VLAN sib txawv;cov neeg siv khoom kawg docked rau ntawm cov hloov pauv tsis muaj kev tswj hwm yog nyob rau hauv tib lub npe tshaj tawm, thiab lawv tsis tuaj yeem tiv thaiv thiab txwv tsis pub;
c.Kev ruaj ntseg ntawm cov ntaub ntawv kis tau tus mob me ntsis qis dua li ntawm hom kev tswj hwm network;
d.Nws tsis tuaj yeem siv rau hauv cov tes hauj lwm loj, nruab nrab thiab me me, thiab muaj qee yam kev txwv rau kev txhawb nqa thiab kev nthuav dav hauv network.
