izimo zokuphepha kwe-switch

Izici zokuphepha ze-switch zimelela isethi ephelele yezinyathelo zokuvikela ezenzelwe ukuvikela ingqalasizinda yenethiwekhi nokudluliswa kwedatha. Lezi zici zihlanganisa izingqimba eziningi zokuzivikela, kuhlanganise nokuphepha kwamatheku, uhlu lokulawula ukufinyelela (ama-ACL), nokuhlukaniswa kwe-VLAN. Ukuphepha kwamatheku kuvumela abaphathi ukuba bacacise ukuthi yimaphi amadivayisi angakwazi ukuxhuma kumatheku okushintsha ngokusekelwe kumakheli e-MAC, okuvimbela ngempumelelo imizamo yokufinyelela engagunyaziwe. Ukuqaliswa kwama-VLAN kwenza kube nokwenzeka ukuhlukaniswa kwenethiwekhi, kwakhiwe izindawo ezikude zokusakaza ezandisa ukuphepha ngokulawula ukuhamba kwethrafikhi phakathi kwezingxenye ezahlukene zenethiwekhi. Izici ezithuthukisiwe zifaka i-Dynamic ARP Inspection (DAI), evimbela ukuhlaselwa kwe-ARP ngokuthuthukisa amaphakethe e-ARP, ne-IP Source Guard, evimbela imizamo ye-IP. Ngaphezu kwalokho, ukuhlola i-DHCP kunikeza ukuvikelwa kumaseva we-DHCP angahlelekile nokuhlaselwa komuntu ophakathi. Uhlaka lokuphepha lweswishi lufaka futhi izindlela zokulawula iziphepho ukuvimbela izikhukhula zenethiwekhi, kanye nokuqinisekiswa kwe-802.1X kokulawulwa kokufinyelela okususelwa ethekwini. Lezi zici zisebenza ndawonye ukuze kwakhiwe ingqalasizinda yokuphepha eqinile evikela izinsongo zangaphakathi nezangaphandle ngenkathi kugcinwa ukusebenza kwenethiwekhi nokwethenjelwa.

Izici zokuphepha ze-switch zinikeza izinzuzo eziningi ezicindezelayo ezenza zibaluleke kakhulu kwingqalasizinda yanamuhla yenethiwekhi. Okokuqala, zinikeza ukulawula okucacile kokufinyelela kwenethiwekhi, okuvumela izinhlangano ukuba zisebenzise izinqubomgomo zokuphepha eziqondile ezingeni lepaki. Lokhu kuqinisekisa ukuthi amadivayisi agunyaziwe kuphela angakwazi ukuxhuma kunethiwekhi, kunciphisa kakhulu ingozi yokufinyelela okungagunyaziwe nokwephulwa kokuphepha okungenzeka. Ukuqaliswa kwama-VLAN kwenza kube nokwenzeka ukuhlukaniswa kwenethiwekhi okuphumelelayo, kuthuthukise kokubili ukuphepha nokusebenza ngokuhlukanisa izinhlobo ezahlukene zethrafikhi namaqembu abasebenzisi. Lokhu kuhlukaniswa kuyigugu ikakhulukazi ezindaweni lapho idatha ebucayi kufanele ihlukaniswe nokugcwala kwenethiwekhi okujwayelekile. Enye inzuzo ebalulekile yikhono lokuhlola izinsongo nokuziphendula. Izici ezinjenge-Storm Control zikhomba ngokuzenzakalelayo futhi zinciphise ukuhlaselwa okungenzeka kwenqatshelwe, kuyilapho ukuhlola kwe-DHCP kuvimbela amaseva we-DHCP angagunyaziwe ekuphazamiseni ukusebenza kwenethiwekhi. Ikhono lesistimu lokugcina amarekhodi anemininingwane yezenzakalo zokuphepha kanye nemizamo yokufinyelela inikeza izindlela zokuhlola eziwusizo zezidingo zokuhambisana nokuphenya kwezokuphepha. Ngaphezu kwalokho, ukuhlanganiswa kwe-802.1X yokuqinisekisa ngezinhlelo ezikhona zokuphathwa kobunikazi kwenza lula ukulawulwa kokufinyelela komsebenzisi ngenkathi kugcinwa izivumelwano eziqinile zokuphepha. Lezi zici zenzelwe ukusebenza nomthelela omncane ekusebenzeni kwenethiwekhi, ukuqinisekisa ukuthi izinyathelo zokuphepha aziphazamisi ukusebenza kahle kokusebenza kwansuku zonke. Ukwehla kwalezi zici zokuphepha kuvumela nezinhlangano ukuthi zikhulise kalula inethiwekhi yazo ngenkathi zigcina izinqubomgomo zokuphepha ezihambisanayo kuzo zonke izingxenye.

Uhlelo Oluthuthukile Lokuvikela Izinsongo

Uhlelo Lokuvikela Usongo Oluthuthukile ngaphakathi kwezici zokuphepha zeswishi lumelela indlela yokuzivikela eyinkimbinkimbi eqhubeka ibheka futhi iphendula ezinsongweni ezingaba khona zokuphepha. Lolu hlelo lusebenzisa izindlela eziningi zokuthola, kuhlanganise ukuhlaziywa kokuziphatha, ukufanisa amasignesha, nokutholwa kokungafani, ukuze kutholakale futhi kungasebenzi izinsongo ngaphambi kokuba zithinte ukusebenza kwenethiwekhi. Amakhono okuqapha esikhathi sangempela aleli hlelo avumela ukusabela ngokushesha emisebenzini esolisayo, kuyilapho ama-algorithms ayo okufunda ahlakaniphile ehlale ezilungiselela izindlela ezintsha zokusongela. Le ndlela yokuvikela ivimbela ukuhlaselwa ngosuku olungelona olwangempela futhi inciphise amathuba okuphulwa kwezokuphepha okuphumelelayo. Lolu hlelo lubuye luhlanganise izici eziphelele zokubhalisa nokubika ezinikeza ukuqonda okuningiliziwe ngezenzakalo zokuphepha nemisebenzi yenethiwekhi.

Ukuphathwa Okuhlakaniphile Kokulawula Ukufinyelela

Isici se-Intelligent Access Control Management sinikeza isixazululo esiphelele sokuphatha ukufinyelela kwenethiwekhi kuwo wonke amachweba okushintsha. Lolu hlelo olucubungulayo luhlanganisa ukuqinisekiswa kwekheli le-MAC, izivumelwano ze-802.1X, nokulawulwa kokufinyelela okusekelwe endimeni ukuze kuqinisekiswe ukuthi amadivayisi nabasebenzisi abagunyaziwe kuphela abangakwazi ukuxhuma kunethiwekhi. Lolu hlelo lusekela izindlela eziningi zokuqinisekisa ubuqiniso futhi lungahlanganiswa nezinsizakalo ezikhona zezinhlu, okwenza kube lula kakhulu futhi kuguquguquke kuzidingo ezihlukahlukene zenhlangano. Ukuphoqelelwa kwenqubomgomo okusheshayo kuqinisekisa ukuthi izinqubomgomo zokuphepha zisetshenziswa ngokuhambisana kuwo wonke amaphuzu okufinyelela enethiwekhi, kuyilapho amandla okuhlinzekela okuzenzakalelayo enza lula inqubo yokwengeza amadivayisi amasha nabasebenzisi kunethiwekhi.

Ukuhlukaniswa kwenethiwekhi nokulawulwa kwethrafikhi

Izimo zokuhwahluka kwenethiwekhi nokubhokelela kwezilungu zinikeza amandla angcono ukulayisha nekusabelana nezindlela zolenethi. Le ndawo ikuvumela ukwakha kwamadoda we-nethi anesiqiniseko ngokusebenzisa i-VLAN kunoma ukubhokelela kwezilungu ezininzi. Abasebenzisi bakuvumelana nokubhokelela ngempumelelo kwezilungu phakathi kwezinye izici zolenethi, ukuze idatha ephatheni ingahlanjekanga kwezilungu ezengeziweyo. Iyinkimbane le-QoS enobuhlungu inikeza amandla yokuthotha izilungu eziphilayo ngenxa yokukhuphisa ukugcina kwenethiwekhi nezimo ezingavumelekiyo. Izimo zokukhangela izilungu ze ndawo zokusebenza zikunceda ukutholwa nokulindela izinkinga ezingaba yimali ngenxa yokuba iyisiguli esiphumelelayo.
