Yooj Yim Network Management Protocol (SNMP) yog daim ntawv thov txheej txheej txheej txheem uas muab cov lus sib txuas lus ntawm SNMP cov thawj coj thiab cov neeg sawv cev. SNMP muab cov qauv txheej txheem thiab ib hom lus siv rau kev saib xyuas thiab tswj cov khoom siv hauv lub network.
SNMP lub moj khaum muaj peb ntu:

SNMP tus thawj tswj hwm - Tus thawj tswj hwm SNMP yog siv los tswj thiab saib xyuas cov haujlwm ntawm lub network hosts siv SNMP.

SNMP tus neeg saib xyuas - Tus neeg sawv cev SNMP yog cov khoom siv software hauv cov cuab yeej tswj hwm uas tswj cov ntaub ntawv rau lub cuab yeej thiab tshaj tawm cov ntaub ntawv no, raws li xav tau, rau kev tswj hwm lub tshuab.
MIB - Lub Chaw Tswj Xyuas Cov Ntaub Ntawv (MIB) yog thaj chaw khaws ntaub ntawv virtual rau kev tswj hwm cov ntaub ntawv, uas suav nrog cov khoom khaws cia.

Tus thawj coj tuaj yeem xa tus neeg sawv cev thov kom tau txais thiab teeb tsa MIB qhov tseem ceeb. Tus neeg sawv cev tuaj yeem teb cov lus thov no.
Kev ywj pheej ntawm qhov kev sib cuam tshuam no, tus neeg sawv cev tuaj yeem xa cov ntawv ceeb toom uas tsis tau thov (raug lossis ceeb toom) rau tus thawj tswj hwm kom ceeb toom tus thawj tswj hwm ntawm lub network.

SNMP Kev Ua Haujlwm
SNMP daim ntawv thov ua cov haujlwm hauv qab no txhawm rau khaws cov ntaub ntawv, hloov kho SNMP cov khoom sib txawv, thiab xa cov ntawv ceeb toom:

SNMP Tau Txais - SNMP GET kev ua haujlwm yog ua los ntawm Network Management Server (NMS) txhawm rau khaws SNMP cov khoom sib txawv.
SNMP Teeb - Lub SNMP SET ua haujlwm yog ua los ntawm Network Management Server (NMS) los hloov kho tus nqi ntawm cov khoom sib txawv.

SNMP Cov Ntawv Ceeb Toom - Ib qho tseem ceeb ntawm SNMP yog nws lub peev xwm los tsim cov ntawv ceeb toom tsis tau thov los ntawm tus neeg sawv cev SNMP.

SNMP Tau
Kev ua haujlwm SNMP GET yog ua los ntawm Network Management Server (NMS) txhawm rau khaws SNMP cov khoom sib txawv. Muaj peb hom kev ua haujlwm GET:

Tau: Rov qab cov khoom piv txwv los ntawm tus neeg sawv cev SNMP.
TAU TXAIS: Retrieves cov khoom tom ntej no kuj sib txawv, uas yog ib tug lexicographical successor mus rau qhov txawv txawv.
GETBULK: Retrieves ib tug loj npaum li cas ntawm cov khoom sib txawv ntawm cov ntaub ntawv, tsis tas yuav tsum tau rov ua haujlwm GETNEXT.
Cov lus txib rau SNMP GET yog:
snmpget -v2c -c [community-name] [NFVIS-box-ip] [tag- npe, example ifSpeed] [index value]

SNMP Taug kev
SNMP taug kev yog SNMP daim ntawv thov uas siv SNMP GETNEXT thov nug ib lub koom haum network rau tsob ntoo ntawm cov ntaub ntawv.
