I-VLAN (Uthungelwano lweNdawo yeNgingqi yeNgingqi) ibizwa ngokuba yi-"Virtual LAN" ngesiTshayina.
I-VLAN ihlula i-LAN ebonakalayo kwi-LAN eninzi enengqiqo, kwaye i-VLAN nganye yindawo yokusasaza.umzilaokanye uluhlu oluthathutshintsha.
Oku kulandelayo kuchaza umthetho we-Vlan osekwe kwizibuko:
Ufikelelo lwezibuko lunokuba yeyeVLAN enye kuphela, ngoko ke iVLAN yayo engagqibekanga yiVLAN apho ikhoyo, akukho mfuneko yakucwangcisa; izibuko le-Hybrid kunye ne-Trunk inokuba ye-VLAN emininzi, ngoko cwangcisa i-ID ye-VLAN engagqibekanga yezibuko.
1. Izibuko lofikelelo: fumana umyalezo ofunyenweyo ngaphandle kwethegi kwaye wongeze iTag engagqibekanga kumyalezo. Xa umyalezo ufunyenwe ngeTag, ① ifumana i-ID yeVLAN iyafana ne-ID yeVLAN ehlala ikhona. Ukuba umyalezo ulahliwe xa iVLAN ID ithunyelwe, iTag iyasuswa.
2. Izibuko letrunk: Xa umyalezo ufunyenwe ngaphandle kweTag, Xa izibuko sele longezwe kwiVLAN engagqibekanga, Pakisha iTag yeVLAN engagqibekanga yomyalezo kwaye uyigqithisele, Xa izibuko lingadibanisi neVLAN engagqibekanga, Lahla. umyalezo; Xa umyalezo ofunyenweyo uphethe iTag, Xa i-ID yeVLAN iyi-ID yeVLAN evunyiweyo ngeli zibuko, Ukufumana umyalezo, Xa i-ID yeVLAN ingeyiyo i-ID yeVLAN evunyelwe yelo zibuko, Lahla umyalezo; Xa uthumela umyalezo, Xa i-ID yeVLAN ifana ne-ID yeVLAN engagqibekanga, susa iTag, Thumela lo myalezo xa i-ID yeVLAN yahlukile kwi-ID yeVLAN engagqibekanga, Ukugcina iTag yoqobo, Thumela umyalezo.
3. Izibuko le-Hybrid: Ukusebenza xa ufumana umyalezo kuyafana naleyo ye-Trunk port. Xa uthumela umyalezo, i-ID ye-VLAN ethwelwe kumyalezo yi-ID ye-VLAN evunyelweyo kwizibuko, kwaye izibuko linokuqwalasela nokuba ithwala iTag xa uthumela umyalezo we-VLAN (ibandakanya i-VLAN engagqibekanga).
Eli nani lilandelayo yi-HDV 8pon port epon yethuolt:
Eyethu i-HDV 8pon port eponoltukuqwalasela okumiselweyo komyalelo we-vlan kwizibuko ngulo: izibuko elingagqibekanga-vlan 100.
Umyalelo wokongeza izibuko kwi-vlan ehambelanayo ngulo: vlan hybrid 100 untagged.Ungatshintsha i-hybrid ukufikelela kunye ne-trunk, kunye ne-untagged ingatshintshwa ibe yithegi, ngokuxhomekeke kwimfuno.
