Ukuxazulula Izinkinga kanye Nezixazululo Zamaphutha Okudlulisa I-Optical Module

Lolu hlobo lwephutha luhlanganisa kakhuluama-port awekho phezulu, ama-port abonisa isimo se-UP kodwa angathumeli noma amukele amaphakethe, imicimbi evamile ye-port up/down, kanye namaphutha e-CRC.
Lesi sihloko sihlaziya lezi zinkinga ezivamile ngokuningiliziwe.

I. Ichweba Alikhuphuki

UkuthathaAmamojula okukhanya angu-10G SFP+/XFPIsibonelo, lapho imbobo ebonakalayo yehluleka ukuvela ngemva kokuxhumeka kwenye idivayisi, ukuxazulula izinkinga kungenziwa kusukela kulezi zici ezinhlanu ezilandelayo:

Isinyathelo 1: Hlola ukuthi ijubane kanye nezindlela ezimbili ziyafana yini kuzo zombili izinhlangothi

Yenzabonisa isifinyezo esibonakalayoumyalo wokubuka isimo sembobo.
Uma kukhona ukungafani, lungiselela isivinini sembobo kanye nemodi ye-duplex usebenzisa i-isivininifuthii-dupleximiyalo.

Isinyathelo 2: Hlola ukuthi imbobo yedivayisi kanye nemojuli yokukhanya kuyahambisana yini nesivinini kanye nemodi ye-duplex

Sebenzisabonisa isifinyezo esibonakalayoumyalo wokuqinisekisa ukucushwa.
Uma kukhona ukungalingani, lungiselela isivinini esifanele kanye nemodi ye-duplex usebenzisa i-isivininifuthii-dupleximiyalo.

Isinyathelo 3: Hlola ukuthi ngabe womabili amachweba asebenza kahle yini

Sebenzisa isivivinyo se-loopback ukuqinisekisa ukuthi ama-port womabili angakhuphuka yini.

• On Amachweba e-10G SFP+ekhadini lomugqa, sebenzisa ikhebula lokunamathisela eliqondile le-10G SFP+ (lokuxhuma ibanga elifushane) noma amamojula e-optical e-SFP+ anezintambo ze-fiber patch.

• On Amachweba e-10G XFP, sebenzisa amamojula e-optical e-XFP kanye ne-optical fiber ukuze uhlole.

Uma imbobo iphakama, imbobo yontanga ayijwayelekile.
Uma imbobo ingakhuphuki, imbobo yendawo ayijwayelekile.
Inkinga ingaqinisekiswa ngokufaka esikhundleni se-port yendawo noma i-port yontanga.

Isinyathelo 4: Hlola ukuthi i-optical module isebenza kahle yini

Hlola kakhuluUlwazi lwe-DDM, amandla okukhanya, ubude be-wavelength, kanye nebanga lokudlulisela.

• Ulwazi lwe-DDM
  Sebenzisabonisa imininingwane ye-transceiver ye-interfaceumyalo wokuhlola ukuthi amapharamitha ajwayelekile yini.
  Uma kuvela ama-alamu, i-optical module ingase ibe nephutha noma ingahambisani nohlobo lwesixhumi esibonakalayo.

• Amandla Okukhanya
  Sebenzisa imitha yamandla okukhanya ukuze uhlole ukuthi amazinga wamandla okukhanya okudlulisa nokwamukela azinzile futhi angaphakathi kwebanga elijwayelekile.

• Ubude begagasi / Ibanga
  Sebenzisabonisa isikhombimsebenzisi se-transceiverumyalo wokuqinisekisa ukuthi ubude be-wavelength kanye nebanga lokudlulisela lamamojula okukhanya kuzo zombili izinhlangothi kuyahambisana yini.

Isinyathelo 5: Hlola ukuthi i-optical fiber ijwayelekile yini

Ngokwesibonelo:

• Amamojula e-optical e-SFP+ yemodi eyodwa kumele asetshenziswe nefayibha yemodi eyodwa.

• Amamojula e-optical e-Multimode SFP+ kumele asetshenziswe ne-fiber ye-multimode.

Uma kukhona ukungalingani, shintsha i-fiber ngohlobo olufanele ngokushesha.

Uma iphutha lingenakutholakala ngemva kokuqeda konke ukuhlolwa okungenhla, kutuswa ukuthi uxhumane nabasebenzi bokusekela ubuchwepheshe bomhlinzeki ukuze uthole usizo.

II. Isimo Sechweba Siphezulu Kodwa Asithumeli Noma Asitholi Amaphakethe

Uma isimo se-port siphezulu kodwa amaphakethe engakwazi ukudluliselwa noma ukwamukelwa, xazulula izinkinga kulezi zici ezintathu ezilandelayo:

Isinyathelo 1: Hlola izibalo zephakethe

Hlola ukuthi isimo se-port kuzo zombili izinhlangothi sihlala siphezulu nokuthi ama-packet counter kuzo zombili izinhlangothi ayanda yini.

Isinyathelo 2: Hlola ukuthi ukucushwa kwephothi kuyayithinta yini indlela yokudlulisa iphakethe

• Okokuqala, hlola ukuthi ngabe kukhona yini ukucushwa kwenethiwekhi okusetshenzisiwe bese uqinisekisa ukuthi kulungile yini. Uma kudingeka, susa konke ukucushwa bese uhlola futhi.

• Okwesibili, hlola ukuthi inani le-port MTU liyini1500Uma i-MTU ingaphezu kuka-1500, shintsha ukucushwa ngokufanele.

Isinyathelo 3: Hlola ukuthi i-port kanye ne-link medium zivamile yini

Shintsha imbobo exhunyiwe bese uyixhuma kwenye imbobo ukuze ubone ukuthi inkinga efanayo iyenzeka yini.
Uma inkinga iqhubeka, shintsha i-optical module.

Uma inkinga ingenakuxazululwa ngemva kokuhlolwa okungenhla, kunconywa ukuthi uxhumane nabasebenzi bokusekela ubuchwepheshe bomphakeli.

III. Ichweba Livame Ukukhuphuka Noma Ukuhla

Uma imbobo ebonakalayo ivame ukukhuphukela phezulu noma phansi:

• Okokuqala, qinisekisa ukuthi i-optical module ayijwayelekile yini ngokuhlola ukuthiulwazi lwe-alamu, futhi uxazulule kokubili amamojula e-optical kanye ne-fiber yokuxhuma.

• Kwamamojula okukhanya asekelayoukuqapha ukuxilonga kwedijithali, hlola ulwazi lwe-DDM ukuze unqume ukuthi amandla okukhanya asesilinganisweni esibucayi yini.

  • Umadlulisa amandla okukhanyauma isezingeni elibalulekile, shintsha i-optical fiber noma i-optical module ukuze uqinisekise ukuhambisana.

  • Umathola amandla okukhanyainenani elibalulekile, xazulula inkinga ye-peer optical module kanye ne-connecting fiber.

Uma le nkinga ivele ngeamamojula kagesi optical, zama ukumisa isivinini sembobo kanye nemodi ye-duplex.

Uma inkinga iqhubeka ngemva kokuhlola isixhumanisi, amadivayisi angontanga, kanye nemishini ephakathi, kunconywa ukuthi uxhumane nabasebenzi bokusekela ubuchwepheshe bomhlinzeki.

IV. Amaphutha e-CRC

Isinyathelo 1: Hlola izibalo zephakethe ukuze uthole inkinga

Sebenzisabonisa isikhombikubonaumyalo wokuhlola izibalo zephakethi yamaphutha kuzo zombili izikhombisi-ndlela zokungena kanye nokuphuma bese unquma ukuthi yiziphi izibali ezikhulayo.

• Amaphutha e-CEC, uhlaka, noma ama-throttle ayanda lapho kungena

  • Sebenzisa amathuluzi okuhlola ukuhlola ukuthi isixhumanisi sinephutha yini. Uma kunjalo, shintsha ikhebula lenethiwekhi noma i-optical fiber.

  • Ngaphandle kwalokho, xhuma ikhebula noma i-optical module kwenye imbobo.

    • Uma amaphutha ephinde avele ngemva kokushintsha ama-port, i-port yokuqala ingase ibe nephutha.

    • Uma amaphutha esavela echwebeni elaziwayo, inkinga kungenzeka ukuthi isedivayisini yontanga noma isixhumanisi sokudlulisa esiphakathi.

• Amaphutha okweqa ayanda lapho kungena
  Qalisabonisa isikhombikubonaumyalo izikhathi eziningi ukuhlola ukuthiamaphutha okufakaziyanda.
  Uma kunjalo, lokhu kubonisa ukwanda kokweqiwa kwamandla, okungenzeka kubangelwa ukuminyana kwangaphakathi noma ukuvaleka ngaphakathi kwekhadi lomugqa.

• Amaphutha amakhulu ayanda lapho kungena
  Hlola ukuthi ukucushwa kohlaka olukhulu kuzo zombili izinhlangothi kuyahambisana yini, okuhlanganisa:

  • Ubude bephakethe obuphezulu obuzenzakalelayo

  • Ubude obukhulu bephakethe obuvunyelwe

Isinyathelo 2: Hlola ukuthi amandla e-optical module ajwayelekile yini

Sebenzisabonisa imininingwane ye-transceiver interfaceumyalo wokuhlola amanani okuxilonga edijithali amanje emojuli yokukhanya efakiwe.
Uma amandla okukhanya engajwayelekile, shintsha i-module yokukhanya.

Isinyathelo 3: Hlola ukuthi ukucushwa kwembobo kujwayelekile yini

Sebenzisabonisa isifinyezo esibonakalayoumyalo wokuqinisekisa ukucushwa kwembobo, ugxile ku:

• Isimo sokuxoxisana

• Imodi ye-Duplex

• Isivinini sembobo

Uma kutholakala imodi ye-half-duplex noma ukungafani kwesivinini, lungiselela imodi ye-duplex efanele kanye nesivinini se-port usebenzisa i-i-duplexfuthiisivininiimiyalo.

Isinyathelo 4: Hlola ukuthi i-port kanye ne-transmission medium zivamile yini

Shintsha imbobo exhunyiwe ukuze ubone ukuthi inkinga iyaqhubeka yini.
Uma kunjalo, hlola amadivayisi aphakathi nendawo kanye nemidiya yokudlulisa.
Uma zivamile, shintsha i-optical module.

Isinyathelo 5: Hlola ukuthi imbobo ithola inani elikhulu lamafreyimu okulawula ukugeleza

Sebenzisabonisa isikhombikubonaumyalo wokuhlolauhlaka lokumisa isikhashanaikhawunta.
Uma ikhawunta iqhubeka nokukhula, imbobo ithumela noma yamukela inani elikhulu lamafreyimu okulawula ukugeleza.

Hlola futhi ukuthi ithrafikhi yokungena nokuphuma iphakeme yini nokuthi idivayisi yontanga inekhono elanele lokucubungula ithrafikhi.

Uma kungekho zinkinga ezitholakalayo ngokucushwa, amadivayisi angontanga, noma isixhumanisi sokudlulisa ngemuva kokuqeda konke ukuhlola, sicela uxhumane nethimba lokusekela lobuchwepheshe lomhlinzeki ngqo.
