Xaaladda pseudowire iyo tiriyeyaasha taraafikada: kee baa caddeeya gaarsiinta
Xaaladda hawlgalku waxay sheegaysaa in adeegga la habbeeyay oo uu shaqaynayo; tiriyeyaashu waxay sheegayaan in firamyadu dhaqaaqeen. Ku xidh labadaba index-ka VC oo hubi jihada, joogsiga iyo taageerada MIB.
pseudowire soo sheegaya in uu up yahay wuxuu kuu sheegayaa in adeeggu jiro iyo in labada jihoo ay isku raacsan yihiin in uu taraafik qaadayo. Laakiin ma sheegayo in xitaa hal firam macmiil ah uu waligiis dhex maray. Walxaha xaaladda iyo walxaha tiriyaha waxaa loo qoray ujeeddooyin kala duwan, oo mid ka dhigashada caddeyn ta kale waa halka ay badi dashboard-yadan ku khaldamaan. Isbarbardhiggooda waa shaqada, maxaa yeelay ku kalsoonaanta midkood oo keliya waxay ka jawaabtaa su'aal aan cidna weydiin.
Xaaladda iyo tiriyeyaashu waxay ka jawaabaan su'aalo kala duwan
Gelitaanka ugu weyn ee VC wuxuu qaadaa xaalad hawleed isku dhafan, xaaladdaasna waxay up tahay oo kaliya marka labada xaaladood ee jihada ay up yihiin. Wax kasta oo ka dambeeya waa aqoonsiga lakabka kontoroolka iyo habaynta: wareegga isku-xidhka maxalliga ah, peer-ka, calaamadaynta. Saf ku jira xaaladdan waa bayaan ku saabsan ujeeddo iyo diyaargarow, ma aha firamyada la gudbiyay.
Taraafikadu waxay ku nooshahay shax madax banaan oo tiriyeyaal awood sare leh oo loogu talagalay baakadaha iyo baa'iyada, safafkaasna waxay qaadaan isla index-ka VC. Kobaca halkaas waa caddeyn in firamyadu dhex mareen safkaas gaar ahaan intii lagu jiray muddada aad cabbiratay. Tiriye aan is beddelin waa mugdi iskiis. Adeeg aan firfircoonayn, aruuriyaha akhrinaya safka khaldan iyo dariiqa si aamusan u go'ay dhammaantood waxay soo saaraan isla xariiqda fidsan.
| Question | Object | What it can establish |
|---|---|---|
| Is the service up? | cpwVcOperStatus | Both direction states agree the VC should carry traffic. |
| Which side is down? | cpwVcInboundOperStatus, cpwVcOutboundOperStatus | Direction of the reported fault. |
| Did frames move? | cpwVcPerfTotalTable HC counters | Observed forwarding on that row between two polls. |
| Is the interval clean? | cpwVcPerfTotalDiscontinuityTime | Whether the counter was reset inside the window. |
Shaxda u akhri sida laba tiir oo caddayn ah, ma aha sida hal jaranjaro oo darnaansho ah. Up leh tiriyeyaal fidsan maaha nooc ka xun oo up leh kobac, waa u fiirsasho kale oo leh tallaabo xigta oo kale.
Ku xidh index-ka VC, ma aha lambarka tigidhka
Shaxda VC waxaa lagu indexeeyaa hal tiro buuxda, VC ID, cinwaanka peer-ka, nooca iyo magaca adeeggu waa sifooyinka safkaas. Sifooyinkaas ayaa lagu helaa adeeggaaga; index-ku waa waxa aad ku sii helayso ka dib baaritaanka koowaad. Index-ka interface-ka, magaca wareegga la muujiyay ama calaamadda MPLS maaha index-kaas xitaa marka tirooyinku isku bexaan.
OID-yada tirooyinka ka soo qaado faylka MIB ee ku yaal aruuriyaha halkii aad ka qaadan lahayd qoraal blog, kadib hal mar dhex mar shaxda oo kaydi aqoonsiga aad heshay.

snmpwalk -v2c -c monitor 10.60.4.21 -On CPW-VC-MIB::cpwVcTableDiiwaangeli cinwaanka maamulka iyo index-ka si wadajir ah nidaamka la socodka. Dib-u-habayn waxay adeeg u rari kartaa saf kale, markaasna aruuriyaha magaca ku xidhay VC ID wuxuu sii wadi doonaa inuu sawiro index duugoobay oo wali si edeb leh u jawaabaya.
Jihadu waxay ka dhigan tahay pseudowire, ma aha macmiilka
Tiriyeyaasha soo-galka waxay sharraxaan waxa VC ka helay shabakadda baakad-switchka; tiriyeyaasha soo-saarka waxay sharraxaan waxa uu u gudbiyay dhanka shabakaddaas. PE u jeedda macmiilka, taasi waxay inta badan u dhigmaan soo-dejinta iyo soo-qaadista si kastaba. PE-ga dhexe, ama PE leh peer ku yaal xudunta, isla magacyada walxaha waxay sharraxaan khibradda macmiilka ee lidka ku ah.
Qor khariidad kasta hal mar oo ku hay calaamadda dashboard-ka. Garaafka cinwaankiisu yahay soo-qaadista macmiilka oo dhab ahaan sawira taraafikada xudunta, wuu ka gudbi doonaa dib-u-eegista oo si aamusan u marin habaabi doonaa qof kasta oo u isticmaala go'aamada awoodda. Isla khatartaas waxay khuseysaa digniimo lagu dhisay garaafyadaas, waayo waxay wici doonaan kooxda khaldan. Calaamadee garaaf kasta jihada socodka marka la eego pseudowire, khariidadda macmiilkana ha ku noolaato guddiga u baahan.
Hal tijaabo ayaa ka adkaata akhrinta sharraxaadaha walxaha ee kasta: soo jiid fayl la yaqaan adeegga dhexdiisa, isla markiiba ka dib baadh labada jihoo, oo arag tiriye kee dhaqaaqay. Diiwaangeli natiijada agteeda doorka qalabka, maxaa yeelay qofka xiga wuxuu weydiin doonaa isla su'aasha.
Heerku waa ansax oo kaliya gudaha hal daaqad joogsi ah
Xisaabi heerka sida kororka tiriyaha baa'iyada oo loo qaybiyay sekanooyinka la soo maray, oo ku dhufo sideed si aad u hesho bits per second. U qaado muddada mid aan ansax ahayn haddii tiriyuhu hoos u dhacay, wakiilku dib u bilowday, safku is beddelay ama walxaha joogsigu dhaqaaqay. Tuur muunadda oo fur daaqad cusub halkii aad sawiri lahayd meel sare.
Qaado laba muunad oo leh farqi la yaqaan oo hay timestamps-ka aruuriyaha, ma aha taariikhda terminal-kaaga.

Taasi waa sababta amarka saddexaad uu muhiim u yahay sida labada hore.
Hubi waxa daabacaadda rakiban dhab ahaan taageerto
Qeexitaanka MIB waa qeexitaan, ma aha ballan ku saabsan image-kaaga. Shaxaha way maqnaan karaan, qayb ahaan la hirgelin karaan, ama jiri karaan iyagoo aan buuxin ilaa astaamaha la daaro, isla platform-na way kala duwanaan kartaa daabacaadyada. Qeexitaanka CISCO-IETF-PW-MIB wuxuu ku siinayaa magacyada walxaha; qalabku wuxuu kuu sheegayaa haddii ay jawaabaan.
Baadh labada shax iyo xarigga firmware hal mar, kadib isbarbardhig waxa qoraalka daabacaaddu sheegato.

Haddii shaxda xaaladdu jawaabto oo shaxda waxqabadku aanay jawaabin, isku-xidhka aad ku qorshaysatay qaybta koowaad ma haysto meel uu ku degganaado, waxna ka beddelka waa aruuriyaha ma aha wareegga.
Taxanaha wareegga lagu muransan yahay waa gaaban: xaqiiji aqoonsiga safka index-ka, xaqiiji khariidadda jihada hal gudbin la yaqaan, xisaabi heerka oo kaliya gudaha daaqad joogsi nadiif ah, oo xaqiiji in labada shaxba ay jawaabaan daabacaaddaas. Tallaabo kastaa waxay meesha ka saaraysaa hal sharraxaad suurtagal ah. Marka afarta oo dhan ay sax yihiin oo tiriyeyaashu wali aanay dhaqaaqin, caddayntu waxay u jeeddaa meel ka fog pseudowire. Waa markaas marka qabashada baakadaha wareegga isku-xidhka ay istaahisho.
