  • Tus nqi hauv brackets (% xx) qhia tias tus formatter siv nrog nfdump los tso saib tus nqi no (saib tshooj tom ntej).

Kev muab cov ntaub ntawv khaws cia

  • Cov ntaub ntawv khaws cia hauv /tmp/netflow/nfcapd.yyyymmddHHMM, qhov twg yyyymmddHHMM yog lub sijhawm tsim. Cov npe tseem suav nrog .nfstat file, uas yog siv los saib xyuas lub sijhawm tas sijhawm.
  • Tsis txhob hloov qhov no file. Txhawm rau teeb tsa lub sijhawm tas sijhawm siv admin GUI.
  • Cov files tuaj yeem nyeem tau siv nfdump hais kom ua. nfdump [options] [filter]

Qhia UDP pob ntawv xa los ntawm 192.168.88.100:

  • nfdump -r nfcapd.202006011625 'proto udp thiab src ip 192.168.88.100'
    • Tso saib tag nrho cov ntws ntawm 16:25 thiab 17:25, aggregating bidirectional flows (-B):
  • nfdump -R /tmp/netflow/nfcapd.202006011625:nfcapd.202006011725 -B

Cav ID Interoperability

  • Netflow v5 txhais ob lub cim 8-ntsis: Cav Hom thiab Cav ID. Kev soj ntsuam ntawm Advantech routers xa tsuas yog Cav ID (0..255). Lub Cav Hom yuav ib txwm yog xoom (0). Li no, qhov ntws xa nrog Cav ID = 513 (0x201) yuav tau txais raws li Cav Hom / ID = 0/1.ADVANTECH-Router-App-NetFlow-Pfix-FIG-9
  • Netflow v9 txhais ib tus cim 32-ntsis. Kev sojntsuam ntawm Advantech routers tuaj yeem xa txhua tus lej 32-ntsis, yuav ua li cas-ua li cas lwm cov tuam txhab (xws li Cisco) faib cov cim rau hauv ob lub cim tseg, ua raws li Cav Hom thiab Cav ID. Lub receiver ua raws li tib txoj kev.
  • Li no, qhov ntws xa nrog Cav ID = 513 (0x201) yuav tau txais raws li Cav Hom / ID = 2/1.ADVANTECH-Router-App-NetFlow-Pfix-FIG-10
  • IPFIX txhais ib tus cim 32-ntsis. Kev sojntsuam ntawm Advantech routers tuaj yeem xa tus lej 32-ntsis, tab sis tus neeg sau hauv zos tseem tsis tau khaws cov nqi no. Li no txhua qhov ntws yuav tau txais raws li Cav Hom / ID = 0/0.ADVANTECH-Router-App-NetFlow-Pfix-FIG-11
  • Kev pom zoo: Yog tias koj xav khaws Engine ID hauv cov neeg sau khoom hauv zos, tshawb xyuas Khw Muag Khoom Exporting Engine ID hauv kev teeb tsa, siv Engine ID < 256 thiab tsis txhob siv IPFIX raws tu qauv.
  • Tsheb thauj mus los
  • Kev sojntsuam xa tawm tag nrho cov ntws, piv txwv li txhua pob ntawv uas koom ua ke. Yog tias tsis muaj pob ntawv raug pom zoo rau ib lub sijhawm (Inactive Traffic Timeout), qhov ntws yog suav tias yog tiav thiab qhov kev sojntsuam xa cov ntaub ntawv tsheb mus rau tus neeg sau.
  • Cov ntaub ntawv hais txog a file kev hloov pauv yuav tshwm sim hauv tus neeg sau thaum hloov pauv tiav, uas yuav siv sijhawm ntau heev. Yog tias qhov kev sib kis tau ua haujlwm ntev dhau lawm (Active Traffic Timeout) nws yuav tshwm sim raws li ntau qhov luv luv.
  • Rau example, nrog rau 30 feeb kev khiav tsheb khiav sijhawm, kev sib txuas lus 45 feeb yuav qhia tau tias yog ob qhov dej ntws: ib qho 30 feeb thiab ib qho 15 feeb.

Tsheb thauj mus los

  • Kev sojntsuam xa tawm tag nrho cov ntws, piv txwv li txhua pob ntawv uas koom ua ke. Yog tias tsis muaj pob ntawv raug pom zoo rau ib lub sijhawm (Inactive Traffic Timeout), qhov ntws yog suav tias yog tiav thiab qhov kev sojntsuam xa cov ntaub ntawv tsheb mus rau tus neeg sau.
  • Cov ntaub ntawv hais txog a file kev hloov pauv yuav tshwm sim hauv tus neeg sau thaum hloov pauv tiav, uas yuav siv sijhawm ntau heev. Yog tias qhov kev sib kis tau ua haujlwm ntev dhau lawm (Active Traffic Timeout) nws yuav tshwm sim raws li ntau qhov luv luv.
