Umsebenzi sesona salathisi sithe ngqo

Kuba utshintshelo umaleko ukufikelela jikelele, iziqinisekiso QoS ezilula, iindlela zokhuseleko, inkxaso yezicwangciso zolawulo womnatha, iiprothokholi zomthi ezinabileyo kunye VLANs yonke imisebenzi ebalulekileyo, nangona kunjalo, ukuba uhlalutye ngononophelo, eminye imisebenzi inokwahlulwa ngakumbi phantsi kwenkangeleko elula, kwaye ezi zahlulwe. imisebenzi sesona sizathu siphambili umahluko imveliso kunye nendlela ebalulekileyo ukubonisa ixabiso elongezelelweyo iimveliso. Ukuze unikeze abasebenzisi ukuguquguquka okukhulu kwizicelo ezisebenzayo, umgaqo-nkqubo we-QoS wokutshintsha kufuneka uxhase izicwangciso eziphambili zepakethe zamanqanaba amaninzi, okuphambili kunokumiselwa idilesi ye-MAC, i-VLAN, idilesi ye-IP, kunye nechweba ngokulandelanayo. Ngexesha elifanayo, ukutshintshwa kufuneka kube nolawulo oluhle lokuxinana kunye nokunciphisa amandla okuhamba, inkxaso yeenkonzo ezihlukeneyo ze-Diffserv, kunye nokwahlula ngokuhlakanipha imijelo eyahlukeneyo yesicelo esekelwe kumthombo / indawo yokuya kuyo i-MAC / IP ukuhlangabezana neemfuno ze-multimedia ye-real-time applications. Nangona ezinye iiswitshi kwimarike okwangoku zibanga ukuba zineziqinisekiso ze-QoS, zixhasa kuphela useto oluphambili olukwinqanaba elinye, oluzisa ukuphazamiseka okukhulu kwizicelo ezisebenzayo zabasebenzisi.

VLAN inkxaso

I-VLAN yinethiwekhi yendawo yengingqi. Ngokwahlula uthungelwano lwengingqi kwindawo yenethiwekhi yenethiwekhi yeVLAN yenethiwekhi, ulawulo lwenethiwekhi kunye nokhuseleko lwenethiwekhi lunokomelezwa, kwaye usasazo lwedatha olungeyomfuneko lunokulawulwa, Iqela elisebenzayo kuthungelwano lingatyhutyha uthintelo lwejografi kwinethiwekhi ekwabelwana ngayo, kwaye yahlule i-subnet ngokomsebenzi wolawulo, utshintsho lwabavelisi abahlukeneyo banezakhono ezahlukeneyo zokuxhasa iiVLAN, kunye nenani le-VLAN ezixhaswayo nazo zahlukile. Umsebenzi wolawulo womnatha Ngomsebenzi wolawulo lwenethiwekhi, ungasebenzisa isofthiwe yokulawula ukulawula nokuqwalasela utshintsho, umzekelo, unokulawulwa nge-Web browser, iTelnet, i-SNMP, i-RMON, njl. -party ulawulo software ukulawula ukude iswitshi. Ukutshintsha ngokubanzi kuhlangabezana nemisebenzi yolawulo lwezibalo ze-SNMPMIBI / MIBII, kunye nenkxaso yolawulo lokucwangciswa, ulawulo lomgangatho wenkonzo, ulawulo lwe-alamu kunye nezinye izicwangciso, i-Gigabit eyinkimbinkimbi ngakumbi iya kuxhasa i-RMON yokubeka iliso esebenzayo ngokudibanisa iqela le-RMON eyakhelwe ngaphakathi (i-mini-RMON).

Udityaniso lwekhonkco

Ukudibanisa ikhonkco kunokwenza i-bandwidth yekhonkco phakathi kokutshintsha kunye naphakathi kokutshintsha kunye neeseva zine-scalability enhle kakhulu, umzekelo, ezimbini, ezintathu, kunye ne-4 i-gigabit links zinokudibaniswa kunye ukuphinda kabini i-bandwidth yekhonkco. Cwangcisa amakhonkco angafunekiyo kuthungelwano, kwaye usebenzise iProtocol yeSpanning Tree ukuvala ikhonkco eligcinayo, elingenangqiqo lingenzi iluphu. Nje ukuba ukusilela kwenzeke, ikhonkco eligcinayo livuliwe.

Inkxaso yeprotocol yeVRRP

I-VRRP (i-Virtual Routing Redundancy Protocol) sisisombululo sokuqinisekisa ukuthembeka kwenethiwekhi. Kule protocol, isango elingagqibekanga (DefaultGateway) yesixhobo se-IP ye-terminal kwisixhobo sofikelelo oluninzi ekwabelwana ngaso sixhaswa ngokuphindiweyo, ukuze xa esinye sezixhobo zokutshintsha zomaleko-ntathu siphantsi, isixhobo sogcino siya kuthatha ugqithiso. sebenza ngexesha, Umsebenzisi unikezela ngokunikezela okucacileyo, okuphucula umgangatho wenkonzo yenethiwekhi. Iprotocol ye-VRRP iyafana ne-Cisco's HSRP protocol, kodwa i-HSRP ikwi-Cisco. Okwangoku, abavelisi abatshintshileyo abaqhelekileyo sele bexhasa iprotocol yeVRRP kwiimveliso zabo, kodwa kuya kuthatha ixesha ukuba isetyenziswe ngokubanzi.
