Mumanetiweki emazuva ano, kuve nechokwadi cheiyo loop-yemahara topology yakakosha kuchengetedza kuita kwakaringana uye kuvimbika. Spanning Tree Protocol (STP), yakamisikidzwa seIEEE 802.1D, ndiyo nzira yakakosha inoshandiswa netiweki switch kudzivirira zvishwe zveEthernet. PaToda, isu tinobatanidza STP mune yedu network mhinduro kuti tipe yakasimba uye yakasimba network network.
Chii chinonzi Spanning Tree Protocol?
STP iLayer 2 protocol inogadzira iyo isina loop-yemahara inonzwisisika topology nekugadzira imwe inoshanda nzira pakati petiweki zvishandiso uye kuvhara nzira dzisina basa. Iyi nzira inodzivirira madutu ekutepfenyura uye inova nechokwadi chekufambiswa kwedata kwakanaka mukati metiweki.
STP inoshanda sei?
Root Bridge Election: STP inotanga yasarudza midzi yebhiriji, inozoshanda seyepakati referensi poindi yetiweki. Mamwe maswichi ese anoverengera nzira ipfupi kune iyi mudzi zambuko.
Port role basa: Imwe neimwe switch port inopihwa rimwe reanotevera mabasa:
Root Port (RP): Chiteshi chine yakanakisa nzira yekuenda kumudzi zambuko.
Yakatemerwa Port (DP): Chiteshi chine nzira yakanakisa yekudzika bhiriji kune chaiyo network segment.
Zviteshi zvakavharwa: Zviteshi zvisiri chikamu cheiyo inoshanda topology uye zvakavharwa kudzivirira zvishwe. .
BPDU Exchange: Shanduko dzekuchinjana Bridge Protocol Data Units (BPDUs) kugovera ruzivo nezve network topology. Kutsinhana uku kunobatsira mukuita kwesarudzo uye mukuchengetedza iyo loop-isina topology.
Topology inoshanduka: Kana network topology shanduko ikaitika (sekutadza kwekubatanidza), STP inoverengera nzira yakanakisa uye inogadzirisa zvakare network kuti ichengetedze-isina loop kushanda. .
Sei STP yakakosha
Kudzivirira network zvishwe: Nekuvhara nzira dzisina basa, STP inova nechokwadi chekuti mafuremu haatenderere nekusingaperi, achidya bandwidth uye kugadzirisa zviwanikwa.
Enhanced redundancy: STP inobvumira nzira dzakawanda dzemuviri pakati pekuchinja, ichipa redundancy pasina kukanganisa network kugadzikana.
Kuchinjira kunetiweki shanduko: STP inogadzirisa zvine simba kunetiweki shanduko, sekutadza kwekubatanidza kana kuwedzera, kuchengetedza network ichishanda. .
Kuzvipira kwaToda kune Network Kunakisa
PaToda, tinonzwisisa basa rakakosha rinoitwa neSTP mukuvimbika kwetiweki. Yedu network mhinduro dzakagadzirirwa kutsigira STP, kuve nechokwadi chekuti network yako inoramba yakagadzikana uye inoshanda. Kunyangwe iwe uri kuvaka network nyowani kana optimize iripo, zvigadzirwa zveToda uye hunyanzvi zvinogona kukubatsira iwe kugadzira yakasimba, isina loop-isina network nharaunda.
Kuti uwane rumwe ruzivo rwekuti Toda ingakubatsira sei kuvaka network yakavimbika, ndapota taura neboka redu rekutsigira.
