Kev daws teeb meem thiab kev daws teeb meem rau qhov tsis ua haujlwm ntawm Optical Module Transmission Faults

Hom kev ua txhaum no feem ntau suav nrogcov chaw nres nkoj tsis tuaj txog UP, cov chaw nres nkoj qhia txog qhov xwm txheej UP tab sis tsis xa lossis txais cov pob ntawv, cov xwm txheej nce / nqis ntawm qhov chaw nres nkoj ntau zaus, thiab CRC yuam kev.
Tsab xov xwm no tshuaj xyuas cov teeb meem no kom meej.

I. Chaw nres nkoj tsis tuaj txog

Noj10G SFP + / XFP optical modulesua piv txwv li, thaum lub qhov chaw nres nkoj optical tsis tuaj tom qab txuas nrog lwm lub cuab yeej, kev daws teeb meem tuaj yeem ua tiav los ntawm tsib yam hauv qab no:

Kauj Ruam 1: Xyuas seb hom ceev thiab hom duplex ntawm ob qho kawg puas sib phim

Ua tiav qhovqhia luv luv interfacelus txib kom saib qhov xwm txheej ntawm qhov chaw nres nkoj.
Yog tias muaj qhov tsis sib xws, teeb tsa qhov ceev ntawm qhov chaw nres nkoj thiab hom duplex sivqhov ceevthiabob chavcov lus txib.

Kauj Ruam 2: Xyuas seb qhov chaw nres nkoj ntawm lub cuab yeej thiab lub module optical puas sib phim hauv hom ceev thiab duplex

Siv covqhia luv luv interfacelus txib kom paub tseeb tias qhov configuration.
Yog tias muaj qhov tsis sib xws, teeb tsa qhov ceev thiab hom duplex kom raug sivqhov ceevthiabob chavcov lus txib.

Kauj Ruam 3: Xyuas seb ob lub qhov (ports) puas ua haujlwm zoo

Siv qhov kev sim loopback los xyuas seb ob lub qhov (ports) puas tuaj yeem tuaj txog UP.

• On 10G SFP + chaw nres nkojntawm daim npav kab, siv 10G SFP + txuas ncaj qha cable (rau kev sib txuas luv luv) lossis SFP + optical modules nrog fiber patch cords.

• On 10G XFP chaw nres nkoj, siv XFP optical modules thiab optical fiber rau kev sim.

Yog tias qhov chaw nres nkoj tuaj txog UP, qhov chaw nres nkoj peer tsis zoo.
Yog tias qhov chaw nres nkoj tsis tuaj txog UP, qhov chaw nres nkoj hauv zos tsis zoo.
Qhov teeb meem tuaj yeem txheeb xyuas tau los ntawm kev hloov chaw nres nkoj hauv zos lossis chaw nres nkoj sib koom.

Kauj Ruam 4: Xyuas seb lub optical module puas ua haujlwm zoo

Feem ntau xyuasCov ntaub ntawv DDM, lub zog kho qhov muag, qhov ntev ntawm qhov ntev, thiab qhov deb ntawm kev xa xov.

• Cov Ntaub Ntawv DDM
  Siv covqhia cov ntsiab lus ntawm cov interfaces transceiverlus txib kom xyuas seb cov parameters puas yog qhov qub.
  Yog tias muaj cov tswb ceeb toom tshwm sim, lub optical module tej zaum yuav ua tsis tiav lossis tsis sib xws nrog hom optical interface.

• Lub zog kho qhov muag
  Siv lub ntsuas fais fab optical los sim seb qhov kev xa thiab txais fais fab optical puas ruaj khov thiab nyob hauv qhov ntau thiab tsawg.

• Qhov ntev ntawm lub zog / Qhov nrug
  Siv covqhia txog kev sib txuas lus ntawm lub transceivertxib kom paub tseeb tias qhov wavelength thiab qhov kis tau ntawm cov khoom siv kho qhov muag ntawm ob qho kawg puas sib xws.

Kauj Ruam 5: Xyuas seb qhov fiber ntau puas zoo li qub

Piv txwv li:

• Ib hom SFP + optical modules yuav tsum siv nrog ib hom fiber.

• Multimode SFP + optical modules yuav tsum siv nrog multimode fiber.

Yog tias muaj qhov tsis sib xws, hloov cov fiber nrog hom tsim nyog tam sim ntawd.

Yog tias qhov teeb meem tsis pom tom qab ua tiav tag nrho cov kev kuaj xyuas saum toj no, nws raug nquahu kom tiv tauj cov neeg ua haujlwm pabcuam kev txawj ntawm tus neeg muag khoom kom tau kev pab.

II. Qhov Xwm Txheej Chaw Nres Nkoj Yog UP tab sis Tsis Xa lossis Txais Cov Pob Khoom

Thaum qhov xwm txheej ntawm qhov chaw nres nkoj yog UP tab sis cov pob ntawv tsis tuaj yeem xa lossis tau txais, daws teeb meem los ntawm peb yam hauv qab no:

Kauj Ruam 1: Tshawb xyuas cov ntaub ntawv ntawm pob ntawv

Xyuas seb qhov xwm txheej ntawm qhov chaw nres nkoj ntawm ob qho kawg puas tseem nyob UP thiab seb cov lej suav pob ntawv ntawm ob qho kawg puas nce ntxiv.

Kauj Ruam 2: Xyuas seb qhov chaw nres nkoj puas cuam tshuam rau kev xa pob ntawv

• Ua ntej, xyuas seb puas muaj kev teeb tsa network twg tau siv thiab xyuas seb puas yog. Yog tias tsim nyog, tshem tawm tag nrho cov kev teeb tsa thiab sim dua.

• Qhov thib ob, xyuas seb qhov chaw nres nkoj MTU tus nqi yog1500 xyooYog tias MTU loj dua 1500, hloov kho qhov kev teeb tsa raws li qhov ntawd.

Kauj Ruam 3: Xyuas seb qhov chaw nres nkoj thiab qhov txuas nruab nrab puas zoo li qub

Hloov qhov chaw nres nkoj uas txuas nrog thiab txuas nws mus rau lwm qhov chaw nres nkoj kom pom seb qhov teeb meem tib yam puas tshwm sim.
Yog tias qhov teeb meem tseem muaj, hloov lub optical module.

Yog tias qhov teeb meem tsis tuaj yeem daws tau tom qab kev kuaj xyuas saum toj no, nws raug nquahu kom tiv tauj cov neeg ua haujlwm pabcuam kev txawj ntawm tus neeg muag khoom.

III. Qhov Chaw Nres Nkoj Feem Ntau Mus Rau Saum Toj Los Yog Hauv Qab

Thaum lub qhov rooj optical feem ntau mus rau SAUM lossis DOWN:

• Ua ntej, xyuas kom meej tias lub optical module puas txawv txav los ntawm kev kuaj xyuas nwscov ntaub ntawv ceeb toom, thiab teeb meem ob qho tib si optical modules thiab cov fiber txuas.

• Rau cov khoom siv kho qhov muag uas txhawb nqakev soj ntsuam kuaj mob digital, xyuas cov ntaub ntawv DDM kom paub seb lub zog optical puas nyob ntawm qhov tseem ceeb.

  • Yog tias qhovxa hluav taws xob kho qhov muagyog nyob rau ntawm tus nqi tseem ceeb, hloov cov fiber ntau lossis optical module rau kev txheeb xyuas hla.

  • Yog tias qhovtau txais lub zog opticalyog nyob rau ntawm tus nqi tseem ceeb, teeb meem ntawm cov peer optical module thiab cov fiber txuas.

Thaum qhov teeb meem no tshwm sim nrogcov khoom siv hluav taws xob kho qhov muag, sim teeb tsa qhov ceev ntawm qhov chaw nres nkoj thiab hom duplex.

Yog tias qhov teeb meem tseem muaj tom qab kuaj xyuas qhov txuas, cov khoom siv sib txuas, thiab cov khoom siv nruab nrab, nws raug pom zoo kom tiv tauj cov neeg ua haujlwm pabcuam kev txawj ntse ntawm tus neeg muag khoom.

IV. CRC Yuam Kev

Kauj Ruam 1: Tshawb xyuas cov ntaub ntawv ntawm pob ntawv kom paub qhov teeb meem

Siv covqhia interfacelus txib kom xyuas cov ntaub ntawv yuam kev ntawm pob ntawv hauv ob qho kev taw qhia ingress thiab egress thiab txiav txim siab seb cov txee twg nce ntxiv.

• CEC, thav duab, lossis qhov yuam kev throttles nce ntxiv thaum nkag mus

  • Siv cov cuab yeej kuaj xyuas seb qhov txuas puas muaj teeb meem. Yog tias muaj, hloov cov xov hlau network lossis cov fiber optic.

  • Xwb, txuas lub cable lossis optical module rau lwm qhov chaw nres nkoj.

    • Yog tias qhov yuam kev rov tshwm sim tom qab hloov cov chaw nres nkoj, qhov chaw nres nkoj qub yuav tsis ua haujlwm.

    • Yog tias tseem muaj qhov yuam kev tshwm sim ntawm qhov chaw nres nkoj uas paub zoo, qhov teeb meem yuav tshwm sim nrog lub cuab yeej sib txuas lus lossis qhov txuas kis nruab nrab.

• Cov kev ua yuam kev overrun nce ntxiv thaum nkag mus
  Khiav lubqhia interfacetxib ntau zaus los xyuas seb puas yogcov yuam kev nkagtab tom nce ntxiv.
  Yog tias yog li ntawd, qhov no qhia tau tias muaj kev siv ntau dhau, tej zaum yog vim muaj kev sib tsoo sab hauv lossis kev thaiv hauv daim npav kab.

• Cov yuam kev ntawm Giants nce ntxiv thaum nkag mus
  Xyuas seb cov qauv ntawm ob sab ntawm lub thav duab loj puas sib xws, suav nrog:

  • Qhov ntev tshaj plaws ntawm pob ntawv

  • Qhov ntev tshaj plaws uas tau tso cai rau pob ntawv

Kauj Ruam 2: Xyuas seb lub zog ntawm lub optical module puas zoo li qub

Siv covqhia cov ntsiab lus ntawm transceiver interfacescov lus txib kom xyuas cov nqi kuaj mob digital tam sim no ntawm cov module optical uas tau teeb tsa.
Yog tias lub zog kho qhov muag tsis zoo, hloov lub module kho qhov muag.

Kauj Ruam 3: Xyuas seb qhov chaw nres nkoj puas zoo li qub

Siv covqhia luv luv interfacecov lus txib kom paub tseeb tias qhov chaw nres nkoj teeb tsa, tsom mus rau:

• Kev sib tham txog qhov xwm txheej

• Hom ob chav

• Qhov ceev ntawm chaw nres nkoj

Yog tias pom muaj hom ib nrab-duplex lossis qhov ceev tsis sib xws, teeb tsa hom duplex thiab qhov ceev ntawm qhov chaw nres nkoj kom raug sivob chavthiabqhov ceevcov lus txib.

Kauj Ruam 4: Xyuas seb qhov chaw nres nkoj thiab qhov chaw xa xov puas zoo li qub

Hloov qhov chaw nres nkoj uas txuas nrog kom pom seb qhov teeb meem puas tseem muaj.
Yog tias nws ua li ntawd, xyuas cov khoom siv nruab nrab thiab cov xov xwm xa xov.
Yog tias lawv zoo li qub, hloov lub optical module.

Kauj Ruam 5: Xyuas seb qhov chaw nres nkoj puas tau txais ntau tus lej tswj kev ntws

Siv covqhia interfacekev txib kom kuaj xyuas qhovncua lub thav duabtxee.
Yog tias lub txee txuas ntxiv nce ntxiv, qhov chaw nres nkoj xa lossis tau txais ntau tus lej tswj kev ntws.

Tsis tas li ntawd, xyuas seb qhov kev nkag thiab tawm ntawm cov tsheb khiav ntau dhau thiab seb lub cuab yeej sib koom tes puas muaj peev xwm ua tiav cov tsheb khiav txaus.

Yog tias tsis pom muaj teeb meem nrog kev teeb tsa, cov khoom siv sib txuas, lossis qhov txuas kis tom qab ua tiav tag nrho cov kev kuaj xyuas, thov hu rau pab pawg neeg txhawb nqa kev siv tshuab ntawm tus neeg muag khoom ncaj qha.
