Ukuqonda iProtocol yeSpanning Tree (STP): Ukuphucula uZinzo lweNethiwekhi kunye neToda

Kuthungelwano lwale mihla, ukuqinisekisa i-loop-free topology kubalulekile ukugcina ukusebenza kakuhle kunye nokuthembeka. IProtocol yeSpanning Tree (STP), esemgangathweni njenge-IEEE 802.1D, yeyona ndlela isisiseko esetyenziswa lutshintsho lwenethiwekhi ukuthintela ukurhintyela kwe-Ethernet. E-Toda, sidibanisa i-STP kwizisombululo zethu zenethiwekhi ukubonelela ngeziseko ezingundoqo zothungelwano ezomeleleyo.

Yintoni iProtocol yeSpanning Tree?
I-STP yiprothokholi ye-Layer 2 eyenza i-loop-free logical topology ngokuyila indlela enye esebenzayo phakathi kwezixhobo zenethiwekhi kunye nokuthintela iindlela ezingafunekiyo. Le nkqubo ithintela izaqhwithi zokusasaza kwaye iqinisekisa ukuhanjiswa kwedatha okusebenzayo kuyo yonke inethiwekhi.

Isebenza njani i-STP?
Ulonyulo lweBhulorho yeRoot: I-STP kuqala ikhetha ibhulorho yeengcambu, eya kusebenza njengendawo yesalathiso esembindini womnatha. Zonke ezinye iiswitshi ziya kubala eyona ndlela imfutshane kule bhulorho yeengcambu.

Isabelo sendima yezibuko: Isibuko sokutshintsha ngasinye sabelwe enye yezi ndima zilandelayo:

I-Root Port (RP): Izibuko elineyona ndlela ilungileyo eya kwibhulorho yeengcambu.

Izibuko eliMiselweyo (DP): Izibuko elineyona ndlela ilungileyo kwibhulorho yeengcambu yecandelo elithile lothungelwano.

Izibuko ezivaliweyo: Iizibuko ezingeyonxalenye ye-topology esebenzayo kwaye zivaliwe ukukhusela i-loops. ​

I-BPDU Exchange: Utshintshiselwano lwe-Bridge Protocol Data Units (BPDUs) ukwabelana ngolwazi malunga ne-topology yenethiwekhi. Olu tshintshiselwano lunceda kwinkqubo yonyulo kunye nokugcina i-topology engenalo loop.

I-Topology iyatshintsha: Ukuba utshintsho lwe-topology yenethiwekhi lwenzeka (njengokusilela kwekhonkco), i-STP iphinda ibale eyona ndlela ilungileyo kwaye iphinde iqwalasele inethiwekhi ukuze igcine i-loop-free operation. ​

Kutheni i-STP ibalulekile
Ukuthintela i-loops yenethiwekhi: Ngokuvala iindlela ezingafunekiyo, i-STP iqinisekisa ukuba iifreyimu azikhuphi ngokungapheliyo, zidla i-bandwidth kunye nezixhobo zokusebenza.

I-redundancy ephuculweyo: i-STP ivumela iindlela ezininzi zomzimba phakathi kokutshintsha, ukubonelela ngokugqithiswa ngaphandle kokunciphisa uzinzo lwenethiwekhi.

Ukuziqhelanisa notshintsho lwenethiwekhi: I-STP ilungelelanisa ngokuguquguqukayo kutshintsho lwenethiwekhi, njengokusilela kwekhonkco okanye ukongezwa, ukugcina inethiwekhi isebenza. ​

Ukuzibophelela kukaToda ekuGqweseni kweNethiwekhi
E-Toda, siyayiqonda indima ebalulekileyo edlalwa yi-STP ekuthembekeni kwenethiwekhi. Izisombululo zethu zenethiwekhi ziyilelwe ukuxhasa i-STP, ukuqinisekisa ukuba inethiwekhi yakho ihlala izinzile kwaye isebenza kakuhle. Nokuba wakha inethiwekhi entsha okanye ulungiselela enye esele ikho, iimveliso kunye nobuchule beToda zinokukunceda wenze indawo eqinileyo, engenalo loop yenethiwekhi.

Ukufumana ulwazi oluthe kratya malunga nendlela iToda enokukunceda ngayo ukwakha inethiwekhi ethembekileyo, nceda uqhagamshelane neqela lethu lenkxaso.
