Ukusombulula iingxaki kunye nezisombululo zeempazamo zokudluliselwa kweModyuli ye-Optical

Olu hlobo lwempazamo lubandakanya ikakhuluiiports azifiki UP, iiports zibonisa imeko ye-UP kodwa azithumeli okanye zifumana iipakethi, iziganeko ezixhaphakileyo zeport up/down, kunye neempazamo ze-CRC.
Eli nqaku lihlalutya le micimbi ixhaphakileyo ngokweenkcukacha.

I. Izibuko Aliveli

UkuthathaIimodyuli ze-optical ze-10G SFP+/XFPUmzekelo, xa i-optical port ingaphumeleli ukuvela emva kokuba iqhagamshelwe kwesinye isixhobo, ukusombulula iingxaki kungenziwa kwezi nkalo zintlanu zilandelayo:

Inyathelo 1: Jonga ukuba isantya kunye neendlela ezimbini ezijikelezayo ziyafana na

Yenzabonisa isishwankathelo sojonganoumyalelo wokujonga imeko yezibuko.
Ukuba kukho ukungangqinelani, lungiselela isantya sezibuko kunye nemo ye-duplex usebenzisa iisantyakwayei-dupleximiyalelo.

Inyathelo lesi-2: Jonga ukuba i-port yesixhobo kunye ne-optical module ziyahambelana na kwisantya kunye ne-duplex mode

Sebenzisabonisa isishwankathelo sojonganoumyalelo wokuqinisekisa uqwalaselo.
Ukuba kukho ukungangqinelani, lungiselela isantya esichanekileyo kunye nemodi ye-duplex usebenzisaisantyakwayei-dupleximiyalelo.

Inyathelo lesi-3: Jonga ukuba zombini iizibuko zisebenza kakuhle na

Sebenzisa uvavanyo lwe-loopback ukuqinisekisa ukuba zombini ii-ports zinokuphakama na.

• On Iiports ze-10G SFP+Kwikhadi lomgca, sebenzisa intambo yokuncamathisela ngqo ye-10G SFP+ (kwii-connections ezikufutshane) okanye ii-modules ze-optical ze-SFP+ ezineentambo ze-fiber patch.

• On Iiports ze-10G XFP, sebenzisa iimodyuli ze-XFP optical kunye ne-optical fiber ukuvavanya.

Ukuba i-port ifika PHEZULU, i-peer port ayiqhelekanga.
Ukuba izibuko azinyuki, izibuko lendawo aliqhelekanga.
Le ngxaki ingaqinisekiswa ngokutshintsha i-port yendawo okanye i-port yontanga.

Inyathelo lesi-4: Jonga ukuba imodyuli yokukhanya isebenza kakuhle na

Jonga ngokuyintlokoUlwazi lwe-DDM, amandla okukhanya, ubude bomda, kunye nomgama wokudlulisela.

• Ulwazi lwe-DDM
  Sebenzisabonisa iinkcukacha ze-transceiver ze-interfacesumyalelo wokujonga ukuba iiparameters ziqhelekile na.
  Ukuba kuvela ii-alamu, imodyuli ye-optical isenokuba nempazamo okanye ingahambelani nohlobo lwe-optical interface.

• Amandla okubona
  Sebenzisa imitha yamandla okukhanya ukuze uvavanye ukuba amanqanaba ombane okukhanya okudlulisa nokwamkelayo azinzile na kwaye akwinqanaba eliqhelekileyo.

• Ubude bamaza / Umgama
  Sebenzisabonisa ujongano lwe-transceiverumyalelo wokuqinisekisa ukuba ubude be-wavelength kunye nomgama wokudluliselwa kweemodyuli ze-optical kuzo zombini iziphelo ziyahambelana na.

Inyathelo lesi-5: Jonga ukuba i-optical fiber iqhelekile na

Umzekelo:

• Iimodyuli ze-optical ze-SFP+ zemowudi enye mazisetyenziswe kunye nefayibha yemowudi enye.

• Iimodyuli ze-optical ze-Multimode SFP+ mazisetyenziswe kunye ne-multimode fiber.

Ukuba kukho ukungangqinelani, tshintsha ifayibha ngohlobo olufanelekileyo ngoko nangoko.

Ukuba ingxaki ayinakufunyanwa emva kokugqiba zonke ezi ziphumo zingasentla, kuyacetyiswa ukuba uqhagamshelane nabasebenzi benkxaso yobugcisa bomthengisi ukuze ufumane uncedo.

II. Imeko yePort iphezulu kodwa ayithumeli okanye ayifumani iipakethi

Xa imeko yezibuko iphezulu kodwa iipakethi zingenakudluliselwa okanye zamkelwe, lungisa iingxaki kwezi zinto zintathu zilandelayo:

Inyathelo 1: Jonga izibalo zepakethi

Jonga ukuba imeko yezibuko kuzo zombini iziphelo ihlala iphezulu na kwaye ukuba iikhawuntara zeepakethi kuzo zombini iziphelo ziyanda na.

Inyathelo lesi-2: Jonga ukuba ulungiselelo lwezibuko luchaphazela na ukuhanjiswa kwepakethi

• Okokuqala, jonga ukuba kukho na ulungiselelo lwenethiwekhi olusetyenzisiweyo kwaye uqinisekise ukuba luchanekile na. Ukuba kuyimfuneko, susa zonke ulungiselelo uze uvavanye kwakhona.

• Okwesibini, jonga ukuba ixabiso lezibuko le-MTU likhona na1500Ukuba i-MTU ingaphezulu kwe-1500, lungisa uqwalaselo ngokufanelekileyo.

Inyathelo lesi-3: Jonga ukuba i-port kunye ne-link medium ziqhelekile na

Buyisela i-port eqhagamshelweyo kwaye uyiqhagamshele kwenye i-port ukuze ubone ukuba ingaba ingxaki efanayo iyenzeka na.
Ukuba ingxaki iyaqhubeka, tshintsha i-optical module.

Ukuba le ngxaki ayinakusonjululwa emva kokuhlolwa okungentla, kuyacetyiswa ukuba uqhagamshelane nabasebenzi benkxaso yobugcisa bomthengisi.

III. Izibuko Lihlala Linyuka Okanye Lihla

Xa izibuko elibonakalayo lihlala lisiya phezulu okanye phantsi:

• Okokuqala, qinisekisa ukuba imodyuli yokukhanya ayiqhelekanga na ngokujonga ukubaulwazi lwe-alamu, kwaye ulungise iingxaki zombini iimodyuli ze-optical kunye nefayibha yokudibanisa.

• Kwiimodyuli ze-optical ezixhasaukujonga uxilongo lwedijithali, jonga ulwazi lwe-DDM ukuze ubone ukuba amandla okukhanya akwinqanaba elibalulekileyo na.

  • Ukubathumela amandla okukhanyaxa ixabiso liphezulu, tshintsha i-optical fiber okanye i-optical module ukuze uqinisekise ukuba i-cross-version iyasebenza.

  • Ukubafumana amandla okukhanyaIxabiso liphezulu kakhulu, lungisa ingxaki kwi-peer optical module kunye ne-connecting fiber.

Xa le ngxaki isenzekaiimodyuli zombane ezibonakalayo, zama ukumisela isantya sezibuko kunye nemo ye-duplex.

Ukuba ingxaki iyaqhubeka emva kokujonga ikhonkco, izixhobo ezisebenzisanayo, kunye nezixhobo eziphakathi, kuyacetyiswa ukuba uqhagamshelane nabasebenzi benkxaso yobugcisa bomthengisi.

IV. Iimpazamo zeCRC

Inyathelo 1: Jonga izibalo zepakethi ukuze ubone ingxaki

Sebenzisabonisa ujonganoumyalelo wokujonga izibalo zepakethi yempazamo kuzo zombini iindlela zokungena kunye nokuphuma kwaye umisele ukuba zeziphi iikhawuntara ezikhulayo.

• Iimpazamo ze-CEC, isakhelo, okanye ii-throttle ziyanda xa zingena

  • Sebenzisa izixhobo zokuvavanya ukujonga ukuba ikhonkco alinaziphene na. Ukuba kunjalo, tshintsha intambo yenethiwekhi okanye ifayibha ye-optical.

  • Okanye, qhagamshela intambo okanye imodyuli ye-optical kwenye i-port.

    • Ukuba iimpazamo ziyavela emva kokutshintsha iiports, iport yokuqala isenokuba nempazamo.

    • Ukuba iimpazamo zisaqhubeka kwizibuko elaziwayo, ingxaki isenokuba kwisixhobo esisebenzisana naso okanye kwikhonkco lokudlulisela eliphakathi.

• Iimpazamo zokugqithisa ziyanda xa kungena
  Sebenzisabonisa ujonganoyalela amaxesha amaninzi ukujonga ukubaiimpazamo zokufakaziyanda.
  Ukuba kunjalo, oku kubonisa ukwanda kokugqitha, okusenokuba kubangelwa kukuxinana kwangaphakathi okanye ukuvaleka ngaphakathi kwikhadi lomgca.

• Iimpazamo ezinkulu ziyanda xa zingena
  Jonga ukuba uqwalaselo lwesakhelo esikhulu kuzo zombini iziphelo luyahambelana na, kuquka:

  • Ubude bepakethi obuphezulu obumiselweyo

  • Ubude obuphezulu bepakethi obuvunyelweyo

Inyathelo lesi-2: Jonga ukuba amandla emodyuli ye-optical aqhelekile na

Sebenzisabonisa iinkcukacha ze-transceiver interfacesumyalelo wokujonga amaxabiso oxilongo lwedijithali akhoyo kwimodyuli ye-optical efakiweyo.
Ukuba amandla okukhanya aqhelekanga, tshintsha imodyuli yokukhanya.

Inyathelo lesi-3: Jonga ukuba uqwalaselo lwezibuko luqhelekile na

Sebenzisabonisa isishwankathelo sojonganoumyalelo wokuqinisekisa uqwalaselo lwezibuko, ugxile ku:

• Imeko yengxoxo

• Imo yeDuplex

• Isantya sezibuko

Ukuba imo ye-half-duplex okanye i-speed mismatch ifunyenwe, misela imo ye-duplex echanekileyo kunye ne-port speed usebenzisa i-i-duplexkwayeisantyaimiyalelo.

Inyathelo lesi-4: Jonga ukuba i-port kunye ne-transmission medium ziqhelekile na

Buyisela izibuko eliqhagamshelweyo ukuze ubone ukuba ingxaki iyaqhubeka na.
Ukuba kunjalo, jonga izixhobo eziphakathi kunye nemidiya yokudlulisa.
Ukuba ziqhelekile, tshintsha imodyuli ye-optical.

Inyathelo lesi-5: Jonga ukuba ingaba izibuko lifumana inani elikhulu leefreyimu zokulawula ukuhamba kwamanzi

Sebenzisabonisa ujonganoumyalelo wokujongamisa ifreyimuikhawuntara.
Ukuba ikhawuntara iyaqhubeka nokwanda, izibuko lithumela okanye lifumana inani elikhulu leefreyimu zokulawula ukuhamba kwamanzi.

Kwakhona jonga ukuba ithrafikhi yokungena nokuphuma igqithisile na kwaye ingaba isixhobo sontanga sinamandla aneleyo okucubungula ithrafikhi.

Ukuba akukho ngxaki ifunyenweyo malunga noqwalaselo, izixhobo ezisebenzisanayo, okanye ikhonkco lokudlulisela emva kokugqiba zonke iitshekhi, nceda unxibelelane ngqo neqela lenkxaso yobugcisa lomthengisi.
