Hloov kho qhov uas twb muaj lawm tag nrog cov cwj pwm tshiab yog qhov zoo sib xws los tsim ib qho tag:
Unassigning ib Tag
Unassign a tag los ntawm cov peev txheej, ntxiv tus cwj pwm nc:operation = "delete" rau lubtag> element belongs to the resource. Hauv qab no, peb unassign a tag los ntawm lub monitor.
Rho tawm a Tag
Txhawm rau rho tawm a tag tag nrho los ntawm Chaw Tswj Xyuas, tus cwj pwm nc: kev ua haujlwm = "delete" rov siv dua, tab sis lub sijhawm no siv rau tag nws tus kheej, txhais hauv qab .
Kev daws teeb meem
Teeb meem: Orchestrator thiab Paragon Active Assurance Tawm ntawm Sync
Lub orchestrator thiab Paragon Active Assurance tuaj yeem xaus ntawm sync rau example yog tias kev hloov pauv tau hloov pauv hauv Control Center GUI, lossis yog tias siv qhov kev teeb tsa tsis tiav thiab rov qab mus rau lub xeev dhau los ua tsis tiav.
Nyob rau hauv cov ntaub ntawv ntawm ib tug ua tsis tau tejyam rollback, NETCONF neeg rau zaub mov yuav tsis txais configuration hloov lawm; nws yuav teb nrog cov lus yuam kev uas hais tias kev teeb tsa raug kaw kom txog thaum rov qab los rau hauv sync. Txhawm rau rov qab los ntawm synchronization thiab qhib kev hloov pauv, koj yuav tsum khiav cov lus txib rpc sync-from-ncc uas synchronizes tag nrho cov teeb tsa los ntawm Chaw Tswj Xyuas mus rau cov ntaub ntawv teeb tsa.
CEEB TOOM: Cov confd@netrounds.com tus neeg siv (lossis txhua yam tau teeb tsa) yuav tsum muaj cai superuser rau txhua yam kom ua tiav. Qhov no tuaj yeem ua tiav nrog cov lus txib ncc neeg siv hloov tshiab confd@netrounds.com -is-superuser Yog tias tus neeg siv tsis yog superuser, ceeb toom yuav tshwm sim hais tias tsis yog txhua yam tuaj yeem raug synced, tab sis txhua yam uas tuaj yeem ua tau.
CEEB TOOM: Yog tias koj tus kws ntaus suab paj nruag tseem khaws cov teeb tsa, koj yuav tsum tau rov ua kom zoo li ntawd txij li qhov kev thov teeb tsa (qhov kev teeb tsa uas tus kws tshaj lij xav kom Control Center muaj) yuav tsis raug siv.
Teeb meem: Pib Sync (sync-from-ncc) Ua tsis tiav Vim tsis muaj peev txheej
Yog tias koj sim khiav rpc sync-los ntawm-ncc ntawm tus account uas muaj nws cov teeb tsa tsim nyob rau hauv Control Center GUI, koj yuav khiav mus rau hauv cov teeb meem yog tias tus account muaj cov khoom siv tsis tau. Nws raug nquahu kom koj pib nrog tus account khoob thiab ua txhua qhov kev teeb tsa ntawm nws los ntawm NETCONF. Txwv tsis pub, yog tias koj ntsib teeb meem nrog kev tsis sib haum xeeb, koj yuav tsum tshem tawm cov kev tsis sib haum xeeb ntawm tus account.
Teeb meem: NETCONF cov lus txib ua tsis tiav nrog ncclient.operations.rpc.RPCError: daim ntawv thov kev sib txuas lus tsis ua haujlwm
NETCONF neeg rau zaub mov tsis rov qab txuas mus rau Control Center server tau txais yog tias Control Center rov pib dua. Txhawm rau kho qhov kev sib txuas rau Chaw Tswj Xyuas, rov pib txheej txheem NETCONF: sudo systemctl rov pib netrounds-confd
Cov lus ceeb toom ntawm Daim Ntawv Thov Tus Neeg Saib Xyuas Kev Xeem thiab Cov Khoom Siv Xeem Xeem
Test Agent Applications in ConfD
Ntawm Test Agents, (tshiab) Test Agent Application ua haujlwm txawv me ntsis ntawm (kawg) Test Agent Appliance.
Test Agent Applications tam sim no tsis txhawb interface configuration. Yog li ntawd, YANG schema tso cai rau kev qhia meej qhov khoob qhov kev teeb tsa rau Cov Neeg Ua Haujlwm Zoo li no. Saib “cov nqe lus no” ntawm nplooj 23 rau ib qho example.
Thaum synchronizing lub ConfD database nrog Control Center siv lub sync-from-ncc hais kom ua, koj xav kom lub interface configuration nyob twj ywm khoob thiab tsis txhob overwritten nrog dab tsi muaj nyob rau hauv Control Center. Yog li koj yuav tsum siv tus chij tshwj xeeb -without_interface_config nrog cov lus txib ntawd thaum ua haujlwm nrog Test Agent Applications.
Empty Interface Configuration rau Test Agent Appliance
Raws li tau sau tseg saum toj no, Test Agent Application tsis txhawb kev teeb tsa interface, thiab yog li ntawd nws muaj peev xwm tshem tawm cov kev cuam tshuam hauv YANG schema.
Tab sis kuj tseem muaj cov xwm txheej uas koj yuav xav tshem tawm qhov kev teeb tsa interface los ntawm Test Agent Appliance. Ib example ntawm qhov no tuaj yeem yog qhov xwm txheej orchestration qhov twg koj tab tom tig mus rau Test Agent siv huab-init, thiab koj xav kom lub interface teeb tsa los ntawm qhov ntawd los siv, es tsis txhob cia ConfD overwrite nws li Test Agent los hauv online.
YANG Schema Cov Kev Hloov Pauv Hais Txog Kev Tsis Txaus Siab Interfaces
Txij li tam sim no kev teeb tsa tsis muaj kev sib txuas tau tso cai (los ntawm version 2.34.0 mus rau), nws muaj peev xwm hais meej txhua lub npe cuam tshuam raws li kev nkag mus rau kev ua haujlwm ua ib feem ntawm kev sim lossis saib.
Qhov no yuav tsum muaj peev xwm siv Daim Ntawv Thov Tus Neeg Saib Xyuas Kev Xeem, txij li rau cov no tsis muaj lub npe cuam tshuam tau txhais hauv ConfD. Nco ntsoov, txawm li cas los xij, qhov no kuj txhais tau tias koj tuaj yeem khiav mus rau cov teeb meem yog tias koj tau teeb tsa kev sim lossis saib kom siv qhov tsis muaj qhov cuam tshuam. Yog li thov nco ntsoov qhov no.
Kev txwv thaum sau npe tus neeg ua haujlwm xeem tsim hauv ConfD
Thaum tsim Tus Neeg Saib Xyuas Kev Xeem los ntawm REST lossis NETCONF / YANG API, peb tsis tuaj yeem paub ua ntej nws yog hom twg: Test Agent Appliance lossis Test Agent Application. Qhov no yuav ua kom pom tseeb tsuas yog tom qab Test Agent tau sau npe.
Thaum Tus Neeg Saib Xyuas Kev Xeem tau raug sau npe thiab tau hloov mus ua ib qho ntawm cov pob zeb no, koj tsis raug tso cai rov sau npe ua lwm hom Test Agent. Qhov no txhais tau tias koj tsis raug tso cai ua ntej tso npe ua Tus Neeg Saib Xyuas Kev Xeem, tom qab ntawd rov sau npe nws ua Daim Ntawv Thov Kev Xeem, lossis rov ua dua. Yog hais tias koj xav tau ib tug Test Agent ntawm ntau hom, koj yuav tsum tau tsim ib tug tshiab Test Agent.
Daim ntawv ntxiv: Ntoo Structure ntawm Full YANG Model
Hauv cov ntawv ntxiv no, ntu "Cov Lus dab neeg" ntawm nplooj ntawv 81 piav qhia txog cov ntsiab lus ntawm YANG qauv ntoo qauv tsim nrog cov lus txib pyang -f tsob ntoo.
Ntu "YANG Model Tree Structure" nyob rau nplooj 82 muab cov zis los ntawm cov lus txib uas siv rau netrounds-ncc.yang. Ib feem ntawm cov zis no yog rov ua dua lwm qhov hauv cov ntaub ntawv.
