MICROCHIP Connectivity Fault Management Configuration
ʻIke Huahana
ʻO ka CFM Configuration Guide he palapala e wehewehe ana i ka hoʻonohonoho ʻana i nā hiʻohiʻona Connectivity Fault Management (CFM) no nā pūnaewele. Ua wehewehe ʻia ka CFM e ka IEEE 802.1ag maʻamau a hāʻawi i nā kuʻina a me nā hana no OAM (Operations, Administration, and Maintenance) no nā ala ma o nā alahaka 802.1 a me nā LAN. Hāʻawi ke alakaʻi i nā wehewehe a me nā wehewehe o nā kikowaena mālama, nā hui, nā helu hope, a me nā wahi waena. Hōʻike pū ia i nā kuʻina CFM ʻekolu: Continuity Check Protocol, Link Trace, a me Loopback.
Nā ʻōlelo hoʻohana huahana
- E heluhelu pono i ka CFM Configuration Guide e hoʻomaopopo i ka hoʻonohonoho ʻana i nā hiʻohiʻona CFM.
- E hoʻonohonoho i nā kikowaena mālama me nā inoa a me nā pae e like me nā waiwai i manaʻo ʻia. Pono nā kāʻei kapu o nā mea kūʻai aku ka nui (e laʻa, 7), ma waena o nā kāhuna mea hoʻolako (e laʻa, 3), a ʻo nā kāhuna mea hoʻohana ka mea liʻiliʻi loa (e laʻa, 1).
- E wehewehe i nā hui mālama e like me nā pūʻulu o nā MEP i hoʻonohonoho ʻia me ka MAID like (Maintenance Association Identifier) a me ka pae MD. Pono e hoʻonohonoho ʻia kēlā me kēia MEP me kahi MEPID kūʻokoʻa i loko o kēlā pae MAID a me MD, a pono e hoʻonohonoho ʻia nā MEP āpau me ka papa inoa piha o nā MEPID.
- E hoʻonohonoho i nā helu hope hui mālama mālama (MEPs) ma ka lihi o ke kikowaena e wehewehe i ka palena no ke kikowaena. Pono nā MEP e hoʻouna a loaʻa i nā kiʻi CFM ma o ka hana relay a hoʻokuʻu i nā papa CFM āpau o kona pae a i ʻole ka haʻahaʻa e hele mai ana mai ka ʻaoʻao uea.
- E hoʻonohonoho i nā wahi kikowaena mālama mālama (MIPs) i loko o ke kikowaena akā ʻaʻole ma ka palena. Pono e hoʻopaʻa inoa ʻia nā kiʻi CFM i loaʻa mai nā MEP a me nā MIP ʻē aʻe, aʻo nā kiʻi CFM a pau ma kahi pae haʻahaʻa e pani ʻia a hoʻokuʻu ʻia. ʻO nā MIP he mau kiko passive a pane wale i ka wā i hoʻoulu ʻia e ka CFM trace route a me nā memo loop-back.
- E hoʻonohonoho i ka Continuity Check Protocol (CCP) ma o ka hoʻouna ʻana i nā memo hoʻomau hoʻomau multicast (CCM) i loko i nā MEP ʻē aʻe e ʻike i nā hemahema o ka pilina ma kahi MA.
- E hoʻonohonoho i nā memo Link Trace (LT), ʻike ʻia hoʻi ʻo Mac Trace Route, ʻo ia nā kiʻi multicast i hoʻouna ʻia e ka MEP e hahai i ke ala (hop-by-hop) i kahi MEP e hele ai. Pono kēlā me kēia MEP e loaʻa i kahi Trace Route Reply pololei i ka Originating MEP a hana hou i ka Trace Route Message.
- E hahai i nā ʻōlelo aʻoaʻo a me nā kuʻina ʻē aʻe i hāʻawi ʻia ma ka CFM Configuration Guide no ka holomua o ka hoʻonohonoho ʻana i nā hiʻohiʻona CFM.
Hoʻolauna
Hōʻike kēia palapala i ka hoʻonohonoho ʻana i nā hiʻohiʻona Connectivity Fault Management (CFM). Ua wehewehe ʻia ka Connectivity Fault Management e ka maʻamau IEEE 802.1ag. Ho'ākāka ia i nā kuʻina a me nā hana no ka OAM (Operations, Administration, and Maintenance) no nā ala ma o nā alahaka 802.1 a me nā pūnaewele wahi kūloko (LAN). Ua like ka IEEE 802.1ag me ka Mana'o ITU-T Y.1731, e pili ana i ka nānā 'ana i ka hana.
IEEE 802.1ag
Wehewehe i ka pilina ma waena o nā kikowaena mālama a me nā lawelawe i hāʻawi ʻia e nā alahaka VLAN-aware a me nā alahaka hāʻawi. nā hewa pili i loko o kahi kahua mālama;
Wehewehewehe
- Kahua Mākaukau (MD)
ʻO nā Domain Maintenance he wahi hoʻokele ma kahi pūnaewele. Hoʻonohonoho ʻia nā MD me nā inoa a me nā pae, kahi o nā pae ʻewalu mai ka 0 a hiki i ka 7. Aia kahi pilina hierarchical ma waena o nā kikowaena e pili ana i nā pae. ʻO ka nui o ka domain, ʻoi aku ka kiʻekiʻe o ka waiwai pae. ʻO nā waiwai i manaʻo ʻia o nā pae penei: Domain Mea kūʻai: Nui loa (e laʻa, 7) Domain Provider: Ma waena (e laʻa, 3) Domain Operator: ʻOi loa (e laʻa, 1) - Hui Maintenance (MA)
Ua wehewehe ʻia ma ke ʻano he "set of MEPs, ua hoʻonohonoho ʻia nā mea āpau me ka MAID (Maintenance Association Identifier) a me MD Level, kēlā me kēia mea i hoʻonohonoho ʻia me kahi MEPID kūʻokoʻa i loko o kēlā MAID a me MD Level, a ua hoʻonohonoho ʻia nā mea āpau me ka papa inoa piha o nā MEPID. - Hui Hoʻopau Hoʻopau (MEP) hui mālama
ʻO nā kiko ma ka lihi o ke kāʻei kua, e wehewehe i ka palena no ka domain. Hoʻouna a loaʻa ka MEP i nā kiʻi CFM ma o ka hana relay, hoʻokuʻu i nā papa CFM āpau o kona pae a i ʻole ka haʻahaʻa e hele mai ana mai ka ʻaoʻao uea. - Kahua mālama i ka Lae Kūwaena (MIP)
Nā kiko i loko o kahi kikowaena, ʻaʻole ma ka palena. Hoʻopaʻa ʻia a hoʻouna ʻia nā kiʻi CFM mai nā MEP a me nā MIP ʻē aʻe, pani ʻia a hoʻokuʻu ʻia nā kiʻi CFM a pau ma kahi pae haʻahaʻa. ʻO nā MIP he mau wahi passive, e pane wale i ka wā i hoʻāla ʻia e ke ala ala CFM a me nā memo loop-back.
Nā Kūlana CFM
ʻO IEEE 802.1ag Ethernet CFM (Connectivity Fault Management) nā protocols i ʻekolu protocols. ʻo lākou:
- Kūkākūkā Hoʻomau Hoʻomau (CCP)
Hāʻawi ka Continuity Check Message (CCM) i kahi ala e ʻike ai i nā hemahema o ka pilina ma kahi MA. ʻO nā CCM nā memo multicast. Hoʻopili ʻia nā CCM i kahi kikowaena (MD). ʻAʻole kuhikuhi ʻia kēia mau memo a ʻaʻole noi i pane. Hoʻouna kēlā me kēia MEP i kahi memo hoʻomau multicast hoʻomau i loko i nā MEP ʻē aʻe. - Kahua loulou (LT)
ʻO nā memo Link Trace i ʻike ʻole ʻia ʻo Mac Trace Route he mau kiʻi Multicast i hoʻouna ʻia e ka MEP e hahai i ke ala (hop-by-hop) i kahi MEP e hele ai e like me ka manaʻo me ka User Da.tagram Protocol (UDP) Trace Alanui. Hoʻouna pololei kēlā me kēia MEP e loaʻa i kahi Trace Route Reply i ka Originating MEP, a hana hou i ka Trace Route Message. - Loop-back (LB)
ʻO nā memo Loop-back i ʻike ʻole ʻia ʻo MAC ping he mau papa Unicast i hoʻouna ʻia e ka MEP, ua like lākou i ka manaʻo me ka Internet Control Message Protocol (ICMP) Echo (Ping) memo, ka hoʻouna ʻana iā Loopback i nā MIP e hiki ke hoʻoholo i kahi o kahi hewa. ʻO ka hoʻouna ʻana i kahi leo kiʻekiʻe o nā Loopback Messages hiki ke hoʻāʻo i ka bandwidth, hilinaʻi, a i ʻole jitter o kahi lawelawe, e like me ka ping wai. Hiki i ka MEP ke hoʻouna i kahi Loopback i kekahi MEP a i ʻole MIP i ka lawelawe. ʻAʻole like me nā CCM, ua hoʻomaka ʻia nā memo Loop back a kāpae ʻia.
Nā palena hoʻokō
ʻAʻole kākoʻo ka hoʻokō ʻana i kēia manawa i ka domain Maintenance Intermediate Point (MIP), Up-MEP, Link Trace (LT), a me Loop-back (LB).
