Umsebenzi uyinkomba eqondile kakhulu

Ukuze uthole ukushintshwa kwesendlalelo sokufinyelela okujwayelekile, iziqinisekiso ezilula ze-QoS, izindlela zokuphepha, ukusekelwa kwamasu okuphatha inethiwekhi, izivumelwano zezihlahla ezinwebekayo kanye nama-VLAN konke kuyimisebenzi ebalulekile, noma kunjalo, uma uhlaziya ngokucophelela, eminye imisebenzi ingahlukaniswa ngokuqhubekayo ngaphansi kokubukeka okulula, futhi lezi zihlukaniswe iziqephu. imisebenzi iyisizathu esiyinhloko somehluko wemikhiqizo kanye nendlela ebalulekile yokubonisa inani elengeziwe lemikhiqizo. Ukuze unikeze abasebenzisi ukuguquguquka okukhulu kuzinhlelo zokusebenza ezingokoqobo, inqubomgomo ye-QoS yokushintsha kufanele isekele izilungiselelo zamaphakethe emazingeni amaningi, okubalulekile kungasethwa kukheli le-MAC, i-VLAN, ikheli le-IP, kanye nembobo ngokulandelana. Ngesikhathi esifanayo, ukushintsha kufanele kube nokulawula ukuminyana okuhle namandla okuvimbela ukugeleza, ukusekela izinsizakalo ezihlukene ze-Diffserv, futhi kuhlukanise ngobuhlakani ukusakazwa kwezinhlelo zokusebenza ezihlukene ngokusekelwe kumthombo/indawo okuyiwa kuyo i-MAC/IP ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ze-multimedia zesikhathi sangempela. Nakuba amanye amaswishi emakethe okwamanje athi aneziqinisekiso ze-QoS, asekela kuphela izilungiselelo ezisemqoka ezisezingeni elilodwa, okuletha ukuphazamiseka okuningi ezinhlelweni ezisebenzayo zabasebenzisi.

Ukusekelwa kwe-VLAN

I-VLAN iyinethiwekhi yendawo yendawo ebonakalayo. Ngokuhlukanisa inethiwekhi yendawo ibe izingxenye zenethiwekhi ye-VLAN yenethiwekhi ebonakalayo, ukuphathwa kwenethiwekhi nokuphepha kwenethiwekhi kungaqiniswa, futhi ukusakazwa kwedatha okungadingekile kungalawulwa, Iqembu elisebenzayo kunethiwekhi lingadabula imingcele yendawo kunethiwekhi eyabiwe, futhi ihlukanise i-subnet ngokomsebenzi wokuphatha, ukushintshwa kwabakhiqizi abahlukene banamandla ahlukene okusekela ama-VLAN, futhi inani lama-VLAN asekelwe nalo lihlukile. Umsebenzi wokuphatha inethiwekhi Ngomsebenzi wokuphatha inethiwekhi, ungasebenzisa isofthiwe yokuphatha ukuze ulawule futhi ulungise ukushintsha, isibonelo, ingaphathwa ngesiphequluli sewebhu, i-Telnet, i-SNMP, i-RMON, njll. Ngokuvamile, ukushintsha abakhiqizi bahlinzeka ngesofthiwe yokuphatha noma yesithathu. -isoftware yokuphatha iqembu ukuphatha ukude ukushintshwa. Ukushintsha okujwayelekile kuhlangabezana nemisebenzi yokuphatha izibalo ye-SNMPMIBI/MIBII, nokuphathwa kokuhlelwa kokusekelwa, ukuphathwa kwekhwalithi yesevisi, ukuphathwa kwe-alamu namanye amasu, ukushintshwa kwe-Gigabit okuyinkimbinkimbi kuzosekela ukuqapha okusebenzayo kwe-RMON ngokungeza iqembu le-RMON elakhelwe ngaphakathi (i-mini-RMON).

Ukuhlanganisa isixhumanisi

Ukuhlanganiswa kwesixhumanisi kungenza umkhawulokudonsa wokuxhumanisa phakathi kokushintsha naphakathi kokushintsha namaseva abe nokulinganisa okuhle kakhulu, isibonelo, izixhumanisi ezimbili, ezintathu, nezine zegigabit zingahlanganiswa ukuze kuphindwe kabili umkhawulokudonsa wesixhumanisi. Setha izixhumanisi ezingasasebenzi kunethiwekhi, futhi usebenzise i-Spanning Tree Protocol ukuze uvimbele isixhumanisi esiyisipele, esingenzi iluphu ngokunengqondo. Uma kwenzeka ukwehluleka, isixhumanisi sokulondoloza siyavulwa.

Sekela iphrothokholi ye-VRRP

I-VRRP (I-Virtual Routing Redundancy Protocol) iyisixazululo sokuqinisekisa ukwethembeka kwenethiwekhi. Kule nqubo yomthetho, isango elizenzakalelayo (DefaultGateway) ledivayisi ye-IP yetheminali endaweni yokufinyelela yokufinyelela okuningi okwabelwana ngayo lisekelwa ngokuphindiwe, ukuze kuthi lapho enye yemishini yokushintsha yezendlalelo ezintathu iphansi, idivayisi eyisipele izophatha ukudlulisela phambili. ukusebenza ngesikhathi, Umsebenzisi uhlinzeka ngokunikezela okusobala, okuthuthukisa ikhwalithi yesevisi yenethiwekhi. Iphrothokholi ye-VRRP iyafana nephrothokholi ye-Cisco ye-HSRP, kodwa i-HSRP iphethwe yi-Cisco. Njengamanje, abakhiqizi bamaswishi ajwayelekile sebevele beyisekelile iphrothokholi ye-VRRP emikhiqizweni yabo, kodwa kuzothatha isikhathi ukuthi isetshenziswe kabanzi.
