Ama-TAP we-Mylinking™ Network Bypass anobuchwepheshe bokushaya kwenhliziyo ahlinzeka ngokuvikeleka kwenethiwekhi ngesikhathi sangempela ngaphandle kokudela ukwethembeka noma ukutholakala kwenethiwekhi. I-Mylinking™ Network Bypass TAPs enemojuli ye-Bypass engu-10/40/100G inikeza ukusebenza kwesivinini esiphezulu okudingekayo ukuze kuxhunywe amathuluzi okuphepha nokuvikela ithrafikhi yenethiwekhi ngesikhathi sangempela ngaphandle kokulahlekelwa kwephakethe.
Okokuqala, yini i-Bypass?
Ngokuvamile, idivayisi yezokuphepha yenethiwekhi isetshenziswa phakathi kwamanethiwekhi amabili noma ngaphezulu, njenge-Intranet nenethiwekhi yangaphandle. Uhlelo lohlelo lokusebenza kudivayisi yezokuphepha yenethiwekhi luhlaziya amaphakethe enethiwekhi ukuthola ukuthi izinsongo zikhona yini, bese lidlulisela phambili amaphakethe ngokwemithetho ethile yomzila. Uma idivayisi yezokuphepha yenethiwekhi inephutha, Isibonelo, ngemva kokuhluleka kwamandla noma ukuphahlazeka, izingxenye zenethiwekhi ezixhunywe ocingweni zizolahlekelwa ukuxhumana. Ngalesi sikhathi, uma inethiwekhi ngayinye idinga ukuxhunywa kwenye, kufanele ibe yi-Bypass phambili.
I-Bypas, njengoba negama lisho, iwumsebenzi oweqiwe, okusho ukuthi amanethiwekhi amabili angahanjiswa ngokuqondile ngohlelo lwedivayisi yokuphepha yenethiwekhi ngesimo esithile sokucupha (ukwehluleka kwamandla noma ukuvala shaqa). Ngemva kokuthi i-Bypass ivuliwe, lapho idivayisi yokuphepha yenethiwekhi yehluleka, inethiwekhi exhunywe kudivayisi yokudlula ingaxhumana nomunye nomunye. Kulokhu, idivayisi yokudlula ayicubunguli amaphakethe kunethiwekhi.
Okwesibili, ukuhlukaniswa kwe-Bypass kusetshenziswa ngezindlela ezilandelayo:
I-Bypass ihlukaniswe ngamamodi alandelayo: imodi yokulawula noma imodi yokuqalisa
1. Icushwe ukunikezwa kwamandla. Kule modi, umsebenzi we-Bypass unikwe amandla uma idivayisi ingavuliwe. Uma idivayisi ivuliwe, i-Bypass iyavalwa ngokushesha.
2. Ilawulwa yi-GPIO. Ngemva kokungena ku-OS, ungasebenzisa i-GPIO ukusebenzisa amachweba athile ukuze ulawule ukushintshwa kwe-Bypass.
3, ngokulawulwa kwe-Watchdog. Lesi isandiso seNdlela yesi-2. Ungasebenzisa i-Watchdog ukuze ulawule ukunika amandla futhi ukhubaze uhlelo lwe-GPIO Bypass, ukuze ulawule isimo se-Bypass. Ngale ndlela, i-Bypass ingavulwa yi-Watchdog uma isiteji siphahlazeka.
Ezisetshenziswa ezingokoqobo, lezi zifunda ezintathu zivame ukuba khona ngesikhathi esisodwa, ikakhulukazi izindlela ezimbili 1 kanye no-2. Indlela yokufaka evamile ithi: Uma idivayisi ivaliwe, i-Bypass ivuliwe. Ngemuva kokuthi idivayisi ivuliwe, i-BIOS ingasebenzisa i-Bypass. Ngemuva kokuthi i-BIOS ithathe idivayisi, i-Bypass isavuliwe. I-Bypass ivaliwe ukuze uhlelo lokusebenza lusebenze. Phakathi nayo yonke inqubo yokuqalisa, cishe akukho ukunqanyulwa kwenethiwekhi.
Okokugcina, Ukuhlaziywa komgomo wokusetshenziswa kwe-Bypass
1. Izinga lezingxenyekazi zekhompuyutha
Ezingeni lezingxenyekazi zekhompuyutha, i-relay isetshenziswa kakhulu ukubona i-Bypass. Lawa ma-relay axhumeke kakhulu ezintanjeni zesignali zembobo ngayinye yenethiwekhi embobeni yenethiwekhi ye-Bypass. Isibalo esilandelayo sisebenzisa ikhebula lesignali eyodwa ukukhombisa imodi yokusebenza ye-relay.
Thatha i-trigger yamandla njengesibonelo. Endabeni yokwehluleka kwamandla, ukushintshwa ku-relay kuzogxumela ku-1, okungukuthi, i-Rx esechwebeni le-RJ45 le-LAN1 ixhumana ngokuqondile ne-RJ45 Tx ye-LAN2. Uma idivayisi ivuliwe, iswishi izoxhumeka ku-2. Udinga ukwenza lokho ngohlelo lokusebenza olukule divayisi.
2. Izinga lesofthiwe
Ekuhlukanisweni kwe-Bypass, i-GPIO kanye ne-Watchdog kuxoxwa ngayo ukuze kulawulwe futhi kubangele i-Bypass. Eqinisweni, zombili lezi zindlela zisebenzisa i-GPIO, bese i-GPIO ilawula ukudluliswa kwehadiwe ukwenza ukugxuma okuhambisanayo. Ngokucacile, uma i-GPIO ehambisanayo isethelwe phezulu, i-relay izogxumela endaweni 1. Ngokuphambene, uma inkomishi ye-GPIO isethelwe phansi, i-relay izogxumela endaweni yesi-2.
Ku-Watchdog Bypass, empeleni, ngesisekelo sokulawula okungenhla kwe-GPIO, engeza i-Watchdog control Bypass. Ngemuva kokuthi i-watchdog iqale ukusebenza, setha isenzo sokudlula ku-BIOS. Uhlelo lunika amandla umsebenzi we-Watchdog. Ngemuva kokuthi i-Watchdog iqale ukusebenza, i-Bypass ye-port ehambisanayo inikwe amandla, okwenza idivayisi ibe kusimo se-Bypass. Eqinisweni, i-Bypass nayo ilawulwa yi-GPIO. Kulokhu, ukubhala okuphansi kwe-GPIO kwenziwa yi-Watchdog, futhi akukho ukuhlela okwengeziwe okudingekayo ukuze kubhalwe i-GPIO.
Umsebenzi we-Hardware Bypass uwumsebenzi odingekayo wemikhiqizo yokuphepha yenethiwekhi. Uma idivayisi ivaliwe noma iphazamiseka, izimbobo zangaphakathi nezingaphandle zingaxhunywa kwezinye ukuze zenze ikhebuli yenethiwekhi. Ngale ndlela, ithrafikhi yedatha yabasebenzisi ingadlula kudivayisi ngaphandle kokuthintwa isimo samanje sedivayisi.
