I-Optical module DDM iyindlela yokuqapha imingcele. Ayinayo imisebenzi ye-alamu neyesixwayiso kuphela, kodwa futhi nokubikezela iphutha nemisebenzi yendawo enephutha.
Kunezindlela ezimbili eziyinhloko zokubuka ulwazi lwe-DDM lwemojula yokubona: i-SNMP nomyalo.
1. I-SNMP, okuyi-Simple Network Management Protocol, iyiphrothokholi ejwayelekile esetshenziswa ngokukhethekile kumanodi enethiwekhi yokuphathwa kwenethiwekhi ye-IP. Ulwazi lwe-DDM lwemojula ye-optical lungakwazi ukufunda amandla optical atholiwe namandla adluliselwe optical module ngokusebenzisa i-SNMP.
Uma imojuli yakho yokubona isekela i-DDM, ungavumela lo msebenzi, bese usebenzisa i-Net SNMP (snmpwalk) ukuze ubuze.
Thatha i-Cisco ASR9kshintshanjengesibonelo, funda amandla optical atholiwe futhi adluliselwe amandla optical module optical ngokusebenzisa SNMP.
Qaphela: I-Cisco ASR9kshintshaiyisistimu yokusebenza ye-IOS-XR enenguqulo 5.3.1. I-MIB ithi “CISCO-ENTITY-SENSOR-MIB” futhi i-OID ithi 1.3.6.1.4.1.9.9.1.1.1.1.
1. Yenza le miyalo elandelayo ngethuluzi le-Net SNMP:;
2. Khona-ke isikhombimsebenzisi somugqa womyalo sizobonisa amandla optical atholiwe kanye namanani wamandla optical adlulisiwe.
Qaphela: 10 * log (mW)=dBm
2. Ngenxa yezinhlobo ezahlukene zabahlinzeki bemishini, i-SNMP's MIB (Management Information Base) kanye ne-OID (Izihlonzi Zezinto) zihlukile. Amanye amadivaysi angathola ngokuqondile ulwazi lwe-DDM ngemiyalo elula.
Isibonelo, amaswishi eHuawei angafaka umyalo wokubonisa.
Sebenzisa i-transceiver yesibonisi somyalo [inombolo yokusebenzelana yohlobo lwesixhumi esibonakalayo | slot id] [verbose] ukubuka ulwazi module optical kusixhumi esibonakalayo idivayisi.
Sebenzisa isixhumi esibonakalayo sokuhlolwa kwesibonisi somyalo [inombolo yokusebenzelana yohlobo lwesixhumi esibonakalayo] ukuze ubonise amapharamitha okuxilonga wemojuli yokubona.
