Lub optical module DDM yog ib txoj hauv kev saib xyuas qhov ntsuas.Nws tsis yog tsuas yog lub tswb thiab ceeb toom ua haujlwm xwb, tab sis kuj muaj kev twv ua ntej thiab ua txhaum qhov chaw ua haujlwm.
Muaj ob txoj hauv kev los saib DDM cov ntaub ntawv ntawm qhov kho qhov muag module: SNMP thiab cov lus txib.
1. SNMP, uas yog Tus Txheej Txheem Yooj Yim Network Management Protocol, yog cov txheej txheem txheej txheem tshwj xeeb uas siv rau IP network tswj cov kab ke.Cov ntaub ntawv kho qhov muag DDM tuaj yeem nyeem qhov tau txais lub zog kho qhov muag thiab xa hluav taws xob kho qhov muag ntawm qhov kho qhov muag los ntawm SNMP.
Thaum koj qhov kho qhov muag module txhawb DDM, koj tuaj yeem ua haujlwm no, thiab tom qab ntawd siv Net SNMP (snmpwalk) los nug.
Coj Cisco ASR9k hloov ua piv txwv, nyeem qhov tau txais lub hwj chim kho qhov muag thiab xa hluav taws xob kho qhov muag ntawm qhov kho qhov muag module los ntawm SNMP.
Nco tseg: Cisco ASR9k hloov yog IOS-XR kev khiav hauj lwm nrog lub version 5.3.1.MIB yog "CISCO-ENTITY-SENSOR-MIB" thiab OID yog 1.3.6.1.4.1.9.9.1.1.1.1.
1. Ua raws li cov lus txib hauv qab no los ntawm Net SNMP cov cuab yeej:;
2. Tom qab ntawd cov kab hais kom ua interface yuav tso saib qhov tau txais lub zog kho qhov muag thiab kis tau tus nqi hluav taws xob kho qhov muag.
Nco tseg: 10 * log (mW) = dBm
2. Vim muaj ntau hom khoom siv, SNMP's MIB (Management Information Base) thiab OID (Object Identifiers) txawv.Qee cov khoom siv tau ncaj qha tau DDM cov ntaub ntawv los ntawm cov lus txib yooj yim.
Piv txwv li, Huawei keyboards tuaj yeem nkag mus rau Cov Lus Qhia.
Ua cov lus txib zaub transceiver [interface interface hom interface tus lej |slot slot id] [verbose] saib cov ntaub ntawv kho qhov muag module ntawm lub cuab yeej interface.
Ua kom tiav cov lus txib tso saib kev kuaj mob interface [interface type interface naj npawb] los tso saib qhov ntsuas qhov ntsuas ntawm qhov kho qhov muag module.
