I nā pūnaewele hou, ʻo ka hōʻoia ʻana i kahi topology loop-free he mea koʻikoʻi no ka mālama ʻana i ka hana kūpono a me ka hilinaʻi. ʻO Spanning Tree Protocol (STP), i hoʻopaʻa ʻia e like me IEEE 802.1D, ʻo ia ka mīkini kumu i hoʻohana ʻia e nā hoʻololi pūnaewele e pale i nā puka lou Ethernet. Ma Toda, hoʻohui mākou i ka STP i loko o kā mākou ʻōnaehana pūnaewele e hāʻawi i kahi ʻoihana pūnaewele paʻa a paʻa.
He aha ka Spanning Tree Protocol?
ʻO STP kahi protocol Layer 2 e hana ana i kahi topology logical loop-free ma ke koho ʻana i hoʻokahi ala ikaika ma waena o nā polokalamu pūnaewele a me ka pale ʻana i nā ala ʻē aʻe. Ke pale nei kēia kaʻina hana i nā ʻino hoʻolaha a hōʻoia i ka hoʻouna ʻana i ka ʻikepili kūpono ma ka pūnaewele.
Pehea ka hana o STP?
Koho Alahaka Aʻa: Ua koho mua ʻo STP i kahi alahaka aʻa, kahi e lilo ai ke kikowaena kuhikuhi o ka pūnaewele. E helu nā hoʻololi ʻē aʻe i ke ala pōkole loa i kēia alahaka kumu.
Hāʻawi ʻia i ka port role: Ua hāʻawi ʻia kēlā me kēia port switch i kekahi o kēia mau kuleana:
Root Port (RP): ʻO ke awa me ke ala maikaʻi loa i ke alahaka kumu.
ʻO ke awa i koho ʻia (DP): He awa i loaʻa ke ala maikaʻi loa i ke alahaka kumu no kahi ʻāpana pūnaewele kikoʻī.
Nā awa i ālai ʻia: ʻO nā awa ʻaʻole ʻāpana o ka topology hana a ua ālai ʻia e pale i nā puka lou. ʻ
BPDU Exchange: Hoʻololi i ka hoʻololi ʻana i nā Units Data Protocol Bridge (BPDUs) e kaʻana like i ka ʻike e pili ana i ka topology pūnaewele. Kōkua kēia hoʻololi i ke kaʻina koho a me ka mālama ʻana i kahi topology loop-free.
Hoʻololi Topology: Inā hoʻololi ʻia kahi hoʻololi topology pūnaewele (e like me ka hemahema o ka loulou), helu hou ʻo STP i ke ala maikaʻi loa a hoʻonohonoho hou i ka pūnaewele e mālama i ka hana loop-free. ʻ
No ke aha he mea nui ka STP
Kaohi ʻana i nā puka puka pūnaewele: Ma ke kāohi ʻana i nā ala ʻē aʻe, hōʻoia ʻo STP ʻaʻole e hoʻopaʻa mau ʻia nā kiʻi, e hoʻopau i ka bandwidth a me nā kumuwaiwai hana.
Hoʻonui hou ʻia: ʻae ʻo STP i nā ala kino he nui ma waena o nā hoʻololi, e hāʻawi ana i ka redundancy me ka ʻole o ka hoʻopaʻa ʻana i ka paʻa o ka pūnaewele.
Hoʻololi i nā hoʻololi pūnaewele: Hoʻololi ikaika ʻo STP i nā loli pūnaewele, e like me ka hāʻule ʻana o ka loulou a i ʻole nā mea hoʻohui, e hoʻomau i ka holo ʻana o ka pūnaewele. ʻ
ʻO ka manaʻo o Toda i ka maikaʻi o ka pūnaewele
Ma Toda, maopopo mākou i ke kuleana koʻikoʻi a STP i ka hilinaʻi pūnaewele. Hoʻolālā ʻia kā mākou ʻenehana pūnaewele e kākoʻo iā STP, e hōʻoia i ka paʻa a me ka maikaʻi o kāu pūnaewele. Inā ʻoe e kūkulu nei i kahi pūnaewele hou a i ʻole e hoʻopololei ana i kahi pūnaewele i loaʻa, hiki i nā huahana a me nā loea o Toda ke kōkua iā ʻoe e hana i kahi kaiapuni pūnaewele paʻa, loop-free.
No ka ʻike hou aku e pili ana i ke kōkua ʻana o Toda iā ʻoe e kūkulu i kahi pūnaewele hilinaʻi, e ʻoluʻolu e kelepona i kā mākou hui kākoʻo.
