ʻO ka module optical DDM kahi mea e nānā ai i nā ʻāpana.ʻAʻole ia wale nā hana hoʻāla a me ka ʻōlelo aʻo, akā no ka wānana hewa a me nā hana wahi hewa.
ʻElua mau ala nui e nānā i ka ʻike DDM o ka module optical: SNMP a me ke kauoha.
1. ʻO SNMP, ʻo ia hoʻi ka Simple Network Management Protocol, he protocol maʻamau i hoʻohana kūikawā ʻia no nā node pūnaewele hoʻokele IP.Hiki i ka ʻike DDM module optical ke heluhelu i ka mana optical i loaʻa a me ka mana optical o ka module optical ma o SNMP.
Ke kākoʻo kāu module optical i ka DDM, hiki iā ʻoe ke hoʻohana i kēia hana, a laila hoʻohana i ka Net SNMP (snmpwalk) e nīnau.
E lawe i ka hoʻololi Cisco ASR9k ma ke ʻano he laʻana, e heluhelu i ka mana optical i loaʻa a me ka mana optical o ka module optical ma o SNMP.
'Ōlelo Aʻo: ʻO ka Cisco ASR9k hoʻololi he ʻōnaehana hana IOS-XR me ka mana 5.3.1.ʻO MIB ka "CISCO-ENTITY-SENSOR-MIB" a ʻo OID ka 1.3.6.1.4.1.9.9.1.1.1.1.
1. E hoʻokō i kēia mau kauoha ma o ka mea hana Net SNMP:;
2. A laila, e hōʻike ka laina kauoha i ka mana optical i loaʻa a me nā waiwai mana optical i hoʻouna ʻia.
Nānā: 10 * log (mW)=dBm
2. Ma muli o nā mana like ʻole o nā mea hoʻolako lako, ʻokoʻa ka MIB o SNMP (Management Information Base) a me OID (Object Identifiers).Hiki i kekahi mau mea hana ke kiʻi pololei i ka ʻike DDM ma o nā kauoha maʻalahi.
No ka laʻana, hiki i nā hoʻololi Huawei ke komo i ke kauoha Hōʻike.
E hoʻokō i ka transceiver hōʻike kauoha [helu helu interface ʻano interface |slot slot id] [verbose] e nānā i ka ʻike o ka module optical ma ka ʻaoʻao o ka hāmeʻa.
E hoʻokō i ke kauoha hōʻike transmitter diagnostic interface [interface type interface number] e hōʻike i nā ʻāpana diagnostic o ka module optical.
