Uthungelwano lweentambo kunye neengcingo
Kuluntu lwanamhlanje, i-Intanethi ingene kuzo zonke iinkalo zobomi bethu, apho inethiwekhi eneengcingo kunye neenethiwekhi ezingenazintambo zezona ziqhelekileyo. Okwangoku, eyona nethiwekhi yentambo idumileyo yi-Ethernet. Kodwa ngophuhliso lwetekhnoloji, iinethiwekhi ezingenazingcingo zingena nzulu kubomi bethu...Funda ngokugqithisileyo - NguMlawuli / 31 Oct 22 /0Amagqabantshintshi
I-VLAN engatshintshiyo
Ii-VLAN ezimileyo zikwabizwa ngokuba zii-VLAN ezisekwe kwizibuko. Oku kukuchaza ukuba leliphi izibuko leliphi i-VLAN ID. Ukusuka kwinqanaba lomzimba, ungacacisa ngokuthe ngqo ukuba i-LAN efakiweyo ihambelana ngqo nezibuko. Xa umlawuli weVLAN eqala ukuqwalasela ubudlelwane obuhambelanayo phakathi...Funda ngokugqithisileyo
