MICROCHIP Connectivity Fault Management Configuration
Cov ntaub ntawv khoom
CFM Configuration Guide yog ib daim ntawv qhia txog kev teeb tsa Connectivity Fault Management (CFM) nta rau tes hauj lwm. CFM yog txhais los ntawm IEEE 802.1ag tus qauv thiab muab cov txheej txheem thiab cov kev coj ua rau OAM (Kev Ua Haujlwm, Kev Tswj Xyuas, thiab Kev Saib Xyuas) rau txoj hauv kev los ntawm 802.1 txuas hniav thiab LANs. Phau ntawv qhia muab cov ntsiab lus thiab piav qhia txog kev saib xyuas, koom haum, cov ntsiab lus kawg, thiab cov ntsiab lus nruab nrab. Nws kuj piav txog peb CFM raws tu qauv: Kev Tshawb Fawb Txuas Ntxiv, Txuas Txoj Cai, thiab Loopback.
Cov lus qhia siv khoom
- Nyeem CFM Configuration Guide kom zoo zoo kom nkag siab txog kev teeb tsa CFM nta.
- Configure txij nkawm nrog cov npe thiab qib raws li qhov pom zoo. Cov neeg siv khoom yuav tsum yog qhov loj tshaj plaws (piv txwv li, 7), cov chaw muab kev pabcuam yuav tsum nyob nruab nrab ntawm (xws li, 3), thiab tus neeg teb xov tooj yuav tsum yog qhov tsawg tshaj plaws (piv txwv li, 1).
- Txhais cov koom haum saib xyuas raws li pawg MEPs teeb tsa nrog tib MAID (Maintenance Association Identifier) thiab MD qib. Txhua MEP yuav tsum tau teeb tsa nrog MEPID tshwj xeeb hauv qib MAID thiab MD, thiab txhua tus MEPs yuav tsum tau teeb tsa nrog rau tag nrho cov npe ntawm MEPIDs.
- Teeb tsa lub koom haum txij nkawm kawg cov ntsiab lus (MEPs) ntawm ntug ntawm tus sau los txhais cov ciam teb rau tus sau. MEPs yuav tsum xa thiab tau txais CFM thav duab los ntawm kev ua haujlwm relay thiab tso tseg tag nrho CFM thav ntawv ntawm nws qib lossis qis dua uas tuaj ntawm sab xaim.
- Configure txij nkawm domain nruab nrab cov ntsiab lus (MIPs) sab hauv rau tus sau tab sis tsis nyob ntawm ciam teb. CFM thav ntawv tau txais los ntawm MEPs thiab lwm yam MIPs yuav tsum tau muab teev tseg thiab xa mus, thaum tag nrho cov CFM thav ntawv ntawm qib qis yuav tsum tau nres thiab poob. MIPs yog cov ntsiab lus passive thiab teb tsuas yog thaum tshwm sim los ntawm CFM txoj kev taug qab thiab cov lus rov qab.
- Teeb tsa Continuity Check Protocol (CCP) los ntawm kev xa cov lus sib txuas lus txuas ntxiv mus txuas ntxiv (CCMs) sab hauv mus rau lwm tus MEPs txhawm rau txheeb xyuas kev sib txuas tsis ua haujlwm hauv MA.
- Configure Link Trace (LT) cov lus, tseem hu ua Mac Trace Route, uas yog multicast thav duab uas MEP xa mus taug qab txoj kev (hop-by-hop) mus rau qhov chaw MEP. Txhua tus tau txais MEP yuav tsum xa Txoj Kev Taug Kev Teb ncaj qha mus rau Originating MEP thiab rov tsim dua Cov Lus Qhia Txoj Kev.
- Nco ntsoov ua raws li tag nrho lwm cov lus qhia thiab cov txheej txheem muaj nyob rau hauv CFM Configuration Guide rau kev ua tiav ntawm CFM nta.
Taw qhia
Cov ntaub ntawv no piav qhia yuav ua li cas teeb tsa Connectivity Fault Management (CFM) nta. Connectivity Fault Management yog txhais los ntawm IEEE 802.1ag tus qauv. Nws txhais cov txheej txheem thiab cov kev coj ua rau OAM (Kev Ua Haujlwm, Kev Tswj Xyuas, thiab Kev Saib Xyuas) rau txoj hauv kev los ntawm 802.1 txuas hniav thiab hauv cheeb tsam network (LANs). IEEE 802.1ag feem ntau zoo ib yam nrog ITU-T Pom Zoo Y.1731, uas tseem hais txog kev saib xyuas kev ua haujlwm.
IEEE 802.1 ua
Txhais cov kev txij nkawm, lawv cov ntsiab lus tu vaj tse, thiab cov khoom tswj hwm uas yuav tsum tau tsim thiab tswj hwm lawv txhais cov kev sib raug zoo ntawm cov chaw tu thiab cov kev pabcuam uas muaj los ntawm VLAN-paub txuas hniav thiab cov chaw muab kev txuas piav qhia txog cov txheej txheem thiab cov txheej txheem siv los ntawm kev saib xyuas cov ntsiab lus los tswj thiab kuaj xyuas. connectivity faults nyob rau hauv ib tug txij nkawm;
Lus txhais
- Maintenance Domain (MD)
Maintenance Domains yog qhov chaw tswj xyuas ntawm lub network. MDs tau teeb tsa nrog Cov Npe thiab Qib, qhov twg yim theem ntawm 0 txog 7. Ib qho kev sib raug zoo ntawm cov thawj tswj hwm raws qib. Qhov loj dua, qhov siab dua tus nqi. Pom zoo qhov tseem ceeb ntawm qib yog raws li hauv qab no: Tus Neeg Siv Khoom: Loj tshaj plaws (piv txwv li, 7) Tus Muab Kev Pabcuam: Hauv nruab nrab (piv txwv li, 3) Tus Neeg Siv Khoom: Tsawg tshaj plaws (piv txwv li, 1) - Maintenance Association (MA)
Txhais raws li "cov txheej txheem ntawm MEPs, tag nrho cov uas tau teeb tsa nrog tib MAID (Lub Koom Haum Saib Xyuas Kev Tiv Thaiv Tus Kheej) thiab MD Level, txhua tus tau teeb tsa nrog MEPID tshwj xeeb hauv MAID thiab MD Level, thiab tag nrho cov uas tau teeb tsa nrog lub ua kom tiav cov npe ntawm MEPIDs." - Maintenance Association End Point (MEP)
Cov ntsiab lus ntawm ntug ntawm tus sau, txhais cov ciam teb rau tus sau. A MEP xa thiab tau txais CFM thav duab los ntawm kev ua haujlwm relay, poob tag nrho CFM thav ntawv ntawm nws qib lossis qis dua uas tuaj ntawm sab xaim. - Maintenance domain Intermediate Point (MIP)
Cov ntsiab lus sab hauv mus rau ib qho chaw, tsis nyob ntawm ciam teb. CFM thav ntawv tau txais los ntawm MEPs thiab lwm yam MIPs yog cataloged thiab xa mus, tag nrho cov CFM thav duab ntawm ib theem qis yog nres thiab poob. MIPs yog cov ntsiab lus passive, teb tsuas yog thaum tshwm sim los ntawm CFM txoj kev taug qab thiab cov lus rov qab.
CFM raws tu qauv
IEEE 802.1ag Ethernet CFM (Connectivity Fault Management) raws tu qauv muaj peb txoj cai. Lawv yog:
- Continuity Check Protocol (CCP)
Cov Lus Qhia Ntxiv Ntxiv (CCM) muab ib txoj hauv kev los txheeb xyuas kev sib txuas tsis ua haujlwm hauv MA. CCMs yog multicast lus. CCMs raug kaw rau hauv ib qho chaw (MD). Cov lus no yog unidirectional thiab tsis thov teb. Txhua MEP xa ib lub sij hawm multicast Continuity Check Message sab hauv mus rau lwm tus MEPs. - Txuas Trace (LT)
Txuas Trace cov lus txwv tsis pub hu ua Mac Trace Route yog Multicast thav duab uas MEP xa mus taug qab txoj kev (hop-by-hop) mus rau qhov chaw MEP uas zoo ib yam hauv lub tswv yim rau Cov Neeg Siv Datagram Protocol (UDP) Trace Route. Txhua tus tau txais MEP xa ib Txoj Kev Taug Kev Teb ncaj qha mus rau Originating MEP, thiab rov tsim dua Txoj Cai Txoj Cai. - Rov qab (LB)
Loop-rov qab cov lus txwv tsis pub hu ua MAC ping yog Unicast thav duab uas MEP xa tawm, lawv zoo ib yam hauv lub tswv yim rau Internet Control Message Protocol (ICMP) Echo (Ping) cov lus, xa Loopback mus rau MIP txuas ntxiv tuaj yeem txiav txim siab qhov chaw ntawm qhov txhaum. Xa lub ntim siab ntawm Loopback Cov Lus tuaj yeem ntsuas qhov bandwidth, kev ntseeg tau, lossis jitter ntawm kev pabcuam, uas zoo ib yam li dej nyab ping. MEP tuaj yeem xa ib Loopback rau txhua tus MEP lossis MIP hauv kev pabcuam. Tsis zoo li CCMs, Loop rov qab cov lus tau pib tswj hwm thiab nres.
Kev txwv tsis pub siv
Qhov kev siv tam sim no tsis txhawb nqa Maintenance domain Intermediate Point (MIP), Up-MEP, Link Trace (LT), thiab Loop-back (LB).
