Okwangoku, utshintsho kwimarike lunokwahlulwa lube lutshintsho olulawulwayo kunye nokutshintsha okungalawulwayo. Wazi kangakanani ngezi ntlobo zimbini zokutshintsha? Yintoni umahluko phakathi kwezi zimbini? Ndingakhetha njani?

Yintoni utshintsho lolawulo lwenethiwekhi?

Umnatha wolawulo iswitshi ikakhulu yenza imisebenzi efana nokubeka iliso izibuko switsha, ukwahlula VLANs, kunye nokuseta esiqwini amazibuko ngokusebenzisa izibuko lolawulo. Ngenxa yokuba i-network management switch ine-VLAN, i-CLI, i-SNMP, i-IP yomzila, i-QoS kunye neminye imisebenzi yeempawu, isoloko isetyenziswa kwi-core layer yenethiwekhi, ngokukodwa kumaziko edatha amakhulu kunye nobunzima.

Yintoni utshintsho olungalawulwayo?
Iswitshi engalawulwayo yiplagi-kunye-dlala i-Ethernet iswitshi engasebenzi ngokuthe ngqo idatha. Ekubeni i-non-network yolawulo iswitshi ayifuni naziphi na iisetingi, ingasetyenziswa ngokuplaga kwintambo ye-Intanethi, kwaye ikwabizwa ngokuba yi-side-type switch.

Umahluko phakathi kokutshintsha okulawulwayo kunye nokutshintsha okungalawulwayo
Kungakhathaliseki ukuba itshintshi elawulwayo okanye inguqu engalawulwayo, isetyenziselwa ukwandiswa kwe-port yenethiwekhi kunye nokutshintshwa kwedatha, kodwa inethiwekhi elawulwayo yokutshintsha yongeza uluhlu lwemisebenzi yokulawula kwesi siseko. Utshintsho lolawulo lwenethiwekhi luxhasa uqwalaselo. Iyakwazi ukulawula uthungelwano ngotshintsho loqwalaselo, njengento ephambili, ulawulo lokuhamba kunye ne-ACL. Ukutshintshwa kolawulo lwe-non-network aluxhasi utshintsho lokucwangciswa, ngoko ke imisebenzi yayo ayityebi njengokutshintsha kolawulo lwenethiwekhi. Ayisiyiyo loo nto kuphela, i-network management switch nayo ineengenelo ze-backplane bandwidth enkulu, idatha enkulu yokudlula, izinga lokulahleka kwepakethi ephantsi, ukulibaziseka okuphantsi, kunye nenethiwekhi eguquguqukayo. Nangona kunjalo, ngokuchanekileyo ngenxa yokuba i-network management switch inemisebenzi ecebileyo ukuba ixabiso layo leendleko lihambelana nolawulo olungelulo lwenethiwekhi. Ephakamileyo yokutshintsha.

Unokukhetha njani phakathi kweeswitshi ezilawulwayo nezingalawulwayo?

Ukuqinisekisa ukusebenza kakuhle kwenkqubo yonke yenethiwekhi, kubaluleke kakhulu ukukhetha utshintsho olufanelekileyo. Ke umntu kufuneka akhethe njani phakathi kokutshintsha okulawulwayo kunye nokutshintsha okungalawulwayo? Unokuqwalasela imiba emibini yendawo yenethiwekhi kunye neendleko:

Kumaziko eenkcukacha eziyinkimbinkimbi kunye nothungelwano lwamashishini amakhulu, inethiwekhi kufuneka iqhube ngokuqhubekayo inani elikhulu ledatha. Ngeli xesha, ukutshintshwa kufuneka kuthathe amawaka okuhanjiswa kwedatha yedatha kunye nemisebenzi yokulawula. Kule meko, kububulumko kakhulu ukukhetha iswitshi yolawulo lwenethiwekhi. Ngenxa yokuba ukutshintshwa kokulawulwa kwenethiwekhi kunokwenza ulawulo lokubona kunye nolawulo lolawulo lomsebenzisi kwizixhobo zenethiwekhi ngokwezixhobo kunye nabasebenzisi ekutshintsheni.
Kwiindawo zothungelwano ezilula ezifana neeofisi ezincinci, amakhaya, njl., imisebenzi yolawulo olunzima ayifuni, ngoko unokukhetha ukutshintsha okungalawulwayo kuba ixabiso lokutshintsha okungalawulwayo lixabiso eliphantsi kwaye lifikeleleke ngaphezu kokutshintshwa kwenethiwekhi elawulwayo.
