⑴ Protocol ea marang-rang

Litekanyetso tsa naha tse amehang, maemo a khoebo a Guodian, le maemo a indasteri a ntseng a hlophisoa kaofela a hlakisa hore "marang-rang a ka theoa ho latela litlhoko tsa sistimi ea motlakase, mme protocol ea marang-rang e lokela ho amohela liprothokholo tsa maemo a machabeng:RSTP, MSTP, joalo-joalo.”Ka hona, ntle le ho ts'ehetsa protocol ea poraefete ea Ring e nang le litokelo tse ikemetseng tsa thepa ea mahlale tse ntlafalitsoeng ke moetsi e mong le e mong, sesebelisoa sa Ethernet sa indasteri se tlameha ho ts'ehetsa liprothokholo tsa marang-rang tsa RSTP le MSTP.Ha feela RSTP le MSTP li-protocol tsa machaba tsa marang-rang tsa marang-rang li amoheloa, li-switch Ethernet tsa indasteri tse tsoang ho bahlahisi ba fapaneng li ka theha marang-rang a nang le likarolo tsa topological tse kang naleli, lesale le sefate.
