Kuv paub tseeb tias koj paub txog qhov kev tawm tsam ntawm Network Tap (Test Access Point) thiab hloov chaw nres nkoj ntsuas (SPAN chaw nres nkoj) rau lub hom phiaj saib xyuas Network.Ob leeg muaj lub peev xwm los tsom iav tsheb hauv lub network thiab xa mus rau cov cuab yeej kev nyab xeeb sab nraud xws li kev nkag mus rau cov cuab yeej, cov loggers, lossis cov kws tshuaj xyuas lub network.Span cov chaw nres nkoj tau teeb tsa ntawm lub network kev lag luam hloov pauv uas muaj qhov chaw nres nkoj mirroring muaj nuj nqi.Nws yog qhov chaw nres nkoj tshwj xeeb ntawm qhov kev hloov pauv uas siv daim iav daim ntawv luam ntawm lub network tsheb los ntawm kev hloov mus rau cov cuab yeej ruaj ntseg.Ib qho TAP, ntawm qhov tod tes, yog ib qho khoom siv uas faib cov kev sib txuas hauv network los ntawm lub network mus rau cov cuab yeej ruaj ntseg.TAP tau txais kev sib txuas hauv network hauv ob qho kev qhia hauv lub sijhawm thiab ntawm ib qho kev sib cais.
Cov no yog tsib lub ntsiab zoo ntawm TAP los ntawm SPAN chaw nres nkoj:
1. TAP ntes txhua pob ntawv!
Span Deletes corrupted packets thiab pob ntawv me dua qhov tsawg kawg nkaus.Yog li ntawd, cov cuab yeej kev ruaj ntseg tsis tuaj yeem tau txais tag nrho cov tsheb thauj mus los vim tias cov chaw nres nkoj nthuav dav muab qhov tseem ceeb dua rau kev sib txuas hauv network.Tsis tas li ntawd, RX thiab TX kev khiav tsheb yog sib sau ua ke ntawm ib qho chaw nres nkoj, yog li cov pob ntawv yuav raug muab tso tseg.TAP ntes tag nrho ob txoj kev tsheb khiav ntawm txhua lub hom phiaj chaw nres nkoj, suav nrog cov chaw nres nkoj yuam kev.
2. Ua tiav kev daws teeb meem, tsis muaj kev teeb tsa IP lossis lub zog hluav taws xob xav tau
Passive TAP feem ntau yog siv hauv fiber ntau optic tes hauj lwm.Nyob rau hauv passive TAP, nws tau txais kev khiav tsheb los ntawm ob qho tib si kev taw qhia ntawm lub network thiab faib lub teeb tuaj kom pom 100% ntawm cov tsheb khiav ntawm lub cuab yeej saib xyuas.Passive TAP tsis tas yuav muaj hluav taws xob.Yog li ntawd, lawv ntxiv ib txheej ntawm redundancy, yuav tsum tau saib xyuas me ntsis, thiab txo cov nqi tag nrho.Yog tias koj npaj yuav saib xyuas tooj liab Ethernet tsheb, koj yuav tsum siv TAP nquag.Active TAP xav tau hluav taws xob, tab sis Niagra's Active TAP suav nrog kev siv thev naus laus zis tsis zoo uas tshem tawm cov kev pheej hmoo ntawm kev cuam tshuam kev pabcuam thaum muaj hluav taws xob poob.
3. Zero pob ntawv poob
Network TAP saib xyuas ob qhov kawg ntawm qhov txuas los muab 100% pom kev ntawm ob txoj kev sib txuas hauv network.TAP tsis muab pov tseg ib pob ntawv, tsis hais lawv cov bandwidth.
4. Haum rau nruab nrab mus rau siab siv network
SPAN chaw nres nkoj tsis tuaj yeem ua cov kev sib txuas siv tau zoo heev yam tsis muaj pob ntawv poob.Yog li ntawd, network TAP yog yuav tsum tau nyob rau hauv cov ntaub ntawv no.Yog tias muaj ntau lub tsheb khiav tawm ntawm SPAN dua li tau txais, SPAN chaw nres nkoj yuav dhau mus thiab raug yuam kom muab cov pob ntawv pov tseg.Txhawm rau ntes 10Gb ntawm ob txoj kev tsheb, SPAN chaw nres nkoj xav tau 20Gb ntawm lub peev xwm, thiab 10Gb Network TAP yuav tuaj yeem ntes tag nrho 10Gb ntawm lub peev xwm.
5. TAP Tso cai rau txhua lub tsheb hla dhau, suav nrog VLAN cim npe
Span ports feem ntau tsis tso cai rau VLAN cov ntawv hla dhau, uas ua rau nws nyuaj rau kev txheeb xyuas VLAN teeb meem thiab tsim teeb meem cuav.TAP zam cov teeb meem zoo li no los ntawm kev tso cai rau tag nrho cov tsheb khiav.
