MICROCHIP Yekubatanidza Kutadza Kwekugadzirisa Kugadzirisa

Product Information

Iyo CFM Configuration Guide igwaro rinotsanangura maitiro ekuseta Connectivity Fault Management (CFM) maficha emanetiweki. CFM inotsanangurwa neIEEE 802.1ag chiyero uye inopa maprotocol uye maitiro eOAM (Operations, Administration, and Maintenance) yenzira dzinopfuura 802.1 mabhiriji nemaLAN. Nhungamiro inopa tsananguro uye tsananguro dzenzvimbo dzekuchengetedza, masangano, mapoinzi ekupedzisira, uye mapoinzi epakati. Inotsanangurawo matatu maCFM maprotocol: Kuenderera Kwekutarisa Protocol, Link Trace, uye Loopback.

Mirayiridzo Yekushandiswa Kwechigadzirwa

1. Verenga iyo CFM Configuration Guide nekungwarira kuti unzwisise maitiro ekuseta maficha eCFM.
2. Gadzirisa madomasi ekugadzirisa ane mazita uye mazinga zvichienderana nehunhu hunokurudzirwa. Madomasi emutengi anofanirwa kunge ari makuru (semuenzaniso, 7), nzvimbo dzevanopa dzinofanira kunge dziri pakati (semuenzaniso, 3), uye madomasi evashandisi anofanira kunge ari madiki (semuenzaniso, 1).
3. Tsanangura masangano ekuchengetedza seseti dzeMEPs dzakagadzirirwa neiyo imwechete MAID (Maintenance Association Identifier) ​​uye MD level. Imwe neimwe MEP inofanirwa kugadzirwa ine MEPID yakasarudzika mukati meiyo MAID uye MD level, uye ese maMEP anofanirwa kugadzirwa aine runyorwa rwakakwana rweMEPID.
4. Gadzirisa mapeji ekupedzisira ekugadzirisa (MEPs) kumucheto kwedomasi kuti utsanangure muganho wedomasi. MEPs dzinofanira kutumira uye kugashira CFM mafuremu kuburikidza nebasa relay uye kudonhedza ese maCFM mafuremu edanho rayo kana kudzika anobva kudivi rewaya.
5. Gadzirisa kuchengetedza domain yepakati mapoinzi (MIPs) yemukati kune iyo dura asi kwete pamuganho. Mafuremu eCFM anotambirwa kubva kuMEPs nemamwe maMIP anofanirwa kuverengerwa nekuendeswa mberi, nepo mafuremu ese eCFM ari padanho rezasi anofanirwa kumiswa nekudonhedzwa. MIPs mapoinzi ekuita uye anopindura chete kana akonzeresa neCFM trace nzira uye loop-kumashure meseji.
6. Rongedza Kuenderera Kwekutarisa Protocol (CCP) nekufambisa nguva nenguva multicast Kuenderera Kwekutarisa Mameseji (CCMs) mukati kune mamwe MEPs kuona kukanganisa kwekubatanidza muMA.
7. Gadzirisa Link Trace (LT) mameseji, anozivikanwawo seMac Trace Route, ari multicast mafuremu anofambiswa neMEP kuronda nzira (hop-by-hop) kuenda kunzvimbo yeMEP. Mumwe nemumwe anogamuchira MEP anofanira kutumira Trace Route Reply zvakananga kuOriginating MEP uye gadzira patsva Trace Route Message.
8. Ita shuwa yekutevera mamwe ese mirairo nemaprotocol akapihwa muCFM Configuration Guide yekubudirira kuseta kweCFM maficha.

Nhanganyaya

Gwaro iri rinotsanangura maitiro ekuseta Connectivity Fault Management (CFM) maficha. Kubatana Kukanganisa Management kunotsanangurwa neIEEE 802.1ag chiyero. Inotsanangura maprotocol uye maitiro eOAM (Operations, Administration, and Maintenance) yenzira dzinopfuura ne802.1 mabhiriji uye nharaunda nharaunda network (LANs). IEEE 802.1ag yakafanana zvikuru neITU-T Recommendation Y.1731, iyo inotaura nezvekuongorora mashandiro.

IEEE 802.1ag
Inotsanangura nzvimbo dzekuchengetedza, nzvimbo dzadzo dzekuchengetedza, uye zvinhu zvinotarisirwa zvinodikanwa kugadzira nekuzvitonga. kukanganisa kwekubatanidza mukati mekugadzirisa domain;

Tsanangudzo

• Maintenance Domain (MD)
  Maintenance Domains inzvimbo yekutonga pane network. MDs inogadziriswa neMazita neNhamba, apo mazinga masere anobva ku0 kusvika ku7. Ukama hwehutungamiri huripo pakati pemadomasi zvichienderana nemazinga. Iyo yakakura iyo domain, iyo yakakwirira yezinga kukosha. Hunhu hunokurudzirwa hwemazinga ndeaya anotevera: Mutengi Domain: Yakakura kwazvo (semuenzaniso, 7) Provider Domain: Pakati (eg, 3) Operator Domain: Diki (eg, 1)
• Maintenance Association (MA)
  Inotsanangurwa se "seti yeMEPs, ese akagadziridzwa neiyo imwechete MAID (Maintenance Association Identifier) ​​uye MD Level, imwe neimwe yakagadziridzwa ine MEPID yakasarudzika mukati meiyo MAID uye MD Level, uye ese akagadziridzwa ne runyorwa rwakakwana rweMEPIDs. "
• Maintenance association End Point (MEP)
  Mapoinzi ari kumucheto kwedomasi, tsanangura muganhu wedomasi. A MEP inotumira uye inogamuchira CFM mafuremu kuburikidza nebasa relay, inodonhedza ese maCFM mafuremu edanho rayo kana kudzika anobva kudivi rewaya.
• Maintenance domain Intermediate Point (MIP)
  Inonongedzera mukati menzvimbo, kwete pamuganhu. Mafuremu eCFM anogamuchirwa kubva kuMEPs uye mamwe maMIP anonyorwa uye kuendeswa mberi, ese maCFM mafuremu ari padanho rezasi anomiswa uye anodonhedzwa. MIPs mapoinzi ekungoita, pindura chete kana yakonzerwa neCFM yekutevera nzira uye loop-kumashure meseji.

CFM Protocols
IEEE 802.1ag Ethernet CFM (Connectivity Fault Management) maprotocol anosanganisira maprotocol matatu. Vari:

• Kuenderera Kwekutarisa Protocol (CCP)
  Iyo Kuenderera Kwekutarisa Mharidzo (CCM) inopa nzira yekuona kutadza kwekubatanidza muMA. MaCCM mameseji akawanda. MaCCM akaganhurirwa kune domain (MD). Mameseji aya haana kunanga uye haakumbire mhinduro. Imwe neimwe MEP inotumira nguva nenguva multicast Kuenderera mberi Tarisa Mharidzo mukati kune mamwe MEPs.
• Link Trace (LT)
  Link Trace meseji inozivikanwawo seMac Trace Route ndeye Multicast mafuremu anofambiswa neMEP kuronda nzira (hop-by-hop) kuenda kunzvimbo yeMEP iyo yakafanana nepfungwa kune Mushandisi Da.taggondohwe Protocol (UDP) Trace Route. Imwe neimwe inogamuchira MEP inotumira Trace Route Reply yakananga kuOriginating MEP, uye inovandudza iyo Trace Route Message.
• Loop-back (LB)
  Loop-back meseji dzinozivikanwa seMAC ping ma Unicast mafuremu anotapurirwa neMEP, akafanana mufungwa kune Internet Control Message Protocol (ICMP) Echo (Ping) mameseji, kutumira Loopback kune anotevedzana MIPs anogona kuona nzvimbo yemhosho. Kutumira yakakwira vhoriyamu yeLoopback Messages inogona kuyedza bandwidth, kuvimbika, kana jitter yesevhisi, iyo yakafanana nemafashama ping. MEP inogona kutumira Loopback kune chero MEP kana MIP mubasa. Kusiyana nemaCCM, Loop kumashure mameseji anotangwa zvine hutongi uye anomiswa.

Implementation limitations
Iko kushandiswa kwemazuva ano hakutsigire Maintenance domain Intermediate Point (MIP), Up-MEP, Link Trace (LT), uye Loop-back (LB).
