IITAP (Iindawo zoVavanyo lokufikelela), okwaziwa ngokuba yiItephu yokuphindaphinda, Itephu yoHlanganisa, Ukucofa Okusebenzayo, Itephu yeCopper, Itephu ye-Ethernet, Itephu yokukhanya, Itephu Yokoqobo, njl. IiTaps ziyindlela edumileyo yokufumana idatha yenethiwekhi. Zibonelela ngokubonakala okubanzi kokuhamba kwedatha yenethiwekhi kwaye zijonga ngokuchanekileyo iincoko ezibhekisa kwicala ngalinye ngesantya esipheleleyo, ngaphandle kokulahleka kwepakethi okanye ukubambezeleka. Ukuvela kweeTAPs kuye kwaguqula icandelo lokubeka esweni nokujonga inethiwekhi, ngokusisiseko kwatshintsha iindlela zokufikelela kwiinkqubo zokubeka esweni nokuhlaziya kwaye kwabonelela ngesisombululo esipheleleyo nesiguquguqukayo kuyo yonke inkqubo yokubeka esweni.
Uphuhliso lwetekhnoloji lwangoku luvelise iintlobo ngeentlobo ze-tap: ii-taps ezidibanisa ii-link ezininzi, ii-regeneration taps ezahlula i-traffic ye-link ibe ziinxalenye ezahlukeneyo, ii-bypass taps, kunye nee-matrix tap switches.
Okwangoku, iimpawu zeTap ezidumileyo kushishino ziquka iNetTAP kunye neMylinking, apho iMylinking ibonwa njengophawu oluhle kakhulu lweTap kunye neNPB kushishino lwaseTshayina, olunesabelo esiphezulu semarike, uzinzo kunye nokusebenza kakuhle.
Iingenelo ze-TAP
1. Bamba i-100% yeepakethi zedatha ngaphandle kokulahleka kwepakethi.
2. Iipakethi zedatha ezingavumelekanga zinokujongwa, nto leyo enceda ekusombululeni iingxaki.
3. Izitampu zexesha ezichanekileyo, akukho kulibaziseka kunye nokutshintshwa kwexesha.
4. Ukufakela kube kanye kwenza kube lula ukuqhagamshela nokuhambisa i-analyzer.
Iingxaki ze-TAP
1. Kufuneka uchithe imali eyongezelelweyo ukuze uthenge i-splitter TAP, ebiza kakhulu kwaye ithatha indawo enkulu yerack.
2. Ikhonkco elinye kuphela elinokujongwa ngexesha.
Usetyenziso oluqhelekileyo lwe-TAP
1. Iikhonkco zorhwebo: Ezi linki zifuna amaxesha amafutshane kakhulu okusombulula iingxaki. Ngokufaka ii-TAP kwezi linki, iinjineli zenethiwekhi zinokufumana kwaye zisombulule iingxaki ngequbuliso ngokukhawuleza.
2. Iikhonkco ezingundoqo okanye ezingasemva. Ezi zinokusetyenziswa okuphezulu kwe-bandwidth kwaye azinakuphazamiseka xa kuqhagamshelwa okanye kushukunyiswa i-analyzer. I-TAP iqinisekisa ukubanjwa kwedatha eyi-100% ngaphandle kokulahleka kwepakethi, inika isiqinisekiso sokusebenza kohlalutyo oluchanekileyo lwezi khonkco.
3. I-VoIP kunye ne-QoS: Uvavanyo lomgangatho we-VoIP lufuna ukulinganiswa okuchanekileyo kwe-jitter kunye nokulahleka kwepakethi. I-TAPs ziqinisekisa ngokupheleleyo olu vavanyo, kodwa ii-mirrored ports zinokutshintsha amaxabiso e-jitter kwaye zibonelele ngamazinga okulahleka kwepakethi angaqhelekanga.
4. Ukusombulula iingxaki: Qinisekisa ukuba iipakethi zedatha ezingaqhelekanga nezinempazamo ziyafunyanwa. Iiports ezibonisiweyo ziya kuzihluza ezi pakethi, zithintele iinjineli ekunikezeni ulwazi olubalulekileyo nolupheleleyo lwedatha yokusombulula iingxaki.
5. Ukusetyenziswa kwe-IDS: I-IDS ixhomekeke kulwazi olupheleleyo lwedatha ukuchonga iipatheni zokungena, kwaye i-TAP inokubonelela ngemithombo yedatha ethembekileyo nepheleleyo kwinkqubo yokufumanisa ukungena.
6. Iqela leseva: I-splitter ye-multi-port ingadibanisa amakhonkco e-8/12 ngaxeshanye, ivumela ukutshintsha okukude nokukhululekileyo, okulungeleyo ukujongwa nokuhlaziywa nangaliphi na ixesha.
I-SPAN (Uhlalutyo lweTshintsho lwePort)ikwaziwa ngokuba yiMirrored Port okanye iPort Mirror. Iiswitshi eziphambili zinokukopa iipakethi zedatha ukusuka kwizibuko elinye okanye ngaphezulu ukuya kwizibuko elimiselweyo, elibizwa ngokuba yi "mirror port" okanye "destination port." I-analyzer ingaqhagamshela kwizibuko elibonisiweyo ukuze ifumane idatha. Nangona kunjalo, olu phawu lunokuchaphazela ukusebenza kweswitshi kwaye lubangele ukulahleka kwepakethi xa idatha igcwele kakhulu.
Iingenelo ze-SPAN
1. Ixabiso eliphantsi, akukho zixhobo zongezelelweyo ezifunekayo.
2. Zonke iitrafikhi kwi-VLAN kwiswitshi zinokujongwa ngaxeshanye.
3. Umhlalutyi omnye unokujonga amakhonkco amaninzi.
Iingxaki ze-SPAN
1. Ukujonga ithrafikhi ukusuka kwiizibuko ezininzi ukuya kwizibuko elinye kunokubangela ukugcwala kwe-cache kunye nokulahleka kwepakethe.
2. Iipakethi ziphinda zibekwe ixesha njengoko zidlula kwi-cache, nto leyo eyenza kube nzima ukumisela ngokuchanekileyo izikali zexesha ezifana ne-jitter, uhlalutyo lwexesha lepakethi, kunye ne-latency.
3. Ayikwazi ukujonga iipakethi zempazamo ze-OSI layer 1.2. Uninzi lweeports zokujonga idatha zihluza iipakethi zedatha ezingahambelaniyo, ezingenakubonelela ngolwazi oluneenkcukacha noluluncedo lokusombulula iingxaki.
4. Ngenxa yokuba ithrafikhi yezibuko ezibonisiweyo inyusa umthwalo we-CPU yeswitshi, iya kubangela ukuba ukusebenza kweswitshi kwehle.
Izicelo eziqhelekileyo ze-SPAN
1. Kwiikhonkco ezine-bandwidth ephantsi kunye nobuchule obuhle bokubukisa, ukubukisa ngee-port ezininzi kungasetyenziselwa uhlalutyo oluguquguqukayo kunye nokubeka esweni.
2. Ukubeka esweni intsingiselo yendlela izinto ezenzeka ngayo: Xa ukubekwa esweni ngokuchanekileyo kungadingeki, kuphela iinkcukacha-manani zedatha ezingahambelaniyo nezaneleyo.
3. Uhlalutyo lweProtocol kunye nesicelo: ulwazi olufanelekileyo lwedatha lungabonelelwa ngokulula nangokunoqoqosho kwizibuko lesibuko
4. Ukubeka esweni i-VLAN iyonke: Itekhnoloji yokubukisa ii-port ezininzi ingasetyenziselwa ukujonga ngokulula i-VLAN yonke kwiswitshi.
Intshayelelo kwi-VLAN:
Okokuqala, makhe sazise ingcamango esisiseko yedomeyini yosasazo. Oku kubhekisa kuluhlu apho iifreyimu zosasazo (iidilesi ze-MAC zezo ndawo zonke zi-1) zinokudluliselwa khona, kwaye ngamanye amazwi, uluhlu apho unxibelelwano oluthe ngqo lunokwenzeka khona. Ngokuthe ngqo, kungekuphela nje iifreyimu zosasazo, kodwa neefreyimu ze-multicast kunye neefreyimu ze-unicast ezingaziwayo zinokuhamba ngokukhululekileyo ngaphakathi kwidomeyini yosasazo efanayo.
Ekuqaleni, iswitshi yeLayer 2 yayinokuseka idomeyini enye yokusasaza. Kwiswitshi yeLayer 2 ngaphandle kweeVLAN ezicwangcisiweyo, naluphi na uhlaka lokusasaza lwaluya kuthunyelwa kuzo zonke iiports ngaphandle kweport efumanayo (ukukhukula). Nangona kunjalo, ukusebenzisa iiVLAN kuvumela inethiwekhi ukuba yahlulwe ibe ziidomeyini ezininzi zokusasaza. IiVLAN ziteknoloji esetyenziselwa ukwahlulahlula iidomeyini zokusasaza kwiiswitshi zeLayer 2. Ngokusebenzisa iiVLAN, sinokuyila ngokukhululekileyo ukwakheka kweedomeyini zokusasaza, sandise ukuguquguquka koyilo lwenethiwekhi.
