I-VLAN (Uthungelwano lweNdawo yeNgingqi yeNgingqi) ibizwa ngesiTshayina.
I-VLAN ihlula i-LAN ebonakalayo kwii-LAN ezininzi ezinengqiqo, kwaye i-VLAN nganye yindawo yokusasazwa. Inginginya kwiVLAN inokunxibelelana nemiyalezo ngemowudi yonxibelelwano ye-Ethernet yemveli, kodwa phakathi kwenginginya kwiVLAN eyahlukileyo, unxibelelwano kufuneka luphunyezwe ngezixhobo zomaleko womnatha njenge.umzilaokanye uluhlu oluthathutshintsha.
Nantsi imithetho ye-Vlan esekwe kwizibuko:
Ufikelelo lwezibuko lunokuba yeyeVLAN enye kuphela, ngoko ke iVLAN yayo engagqibekanga yiVLAN ekuyo kwaye ayifuni kusetwa. Izibuko Hybrid kunye Trunk izibuko zingaba zeVLans ngaphezu kwesinye, ngoko ke kufuneka ukuseta i ID VLAN olungagqibekanga kumazibuko.
I-1, izibuko lokufikelela: fumana ipakethi ngaphandle kwethegi, kwaye yongeza i-VLAN Tag engagqibekanga yepakethi; Xa ipakethe efunyenweyo ineTag, ① xa i-ID yeVLAN ifana ne-ID ye-VLAN engagqibekanga, ipakethi yamkelwa; ② xa i-ID ye-VLAN ihluke kwi-ID ye-VLAN engagqibekanga, ipakethi ilahliwe; Xa uthumela ipakethi, i-ID yeVLAN yi-ID ye-VLAN engagqibekanga, ngoko ayifuni ukusetwa, kwaye ithunyelwa emva kokususa iTag.
2. Izibuko letrunk: xa ipakethe efunyenweyo ingenayo iTag, xa izibuko lijoyine iVLAN engagqibekanga, iTag yeVLAN engagqibekanga igqunywe kwipakethi kwaye idluliselwe, xa izibuko lingajoyinanga iVLAN engagqibekanga, ipakethe. ilahliwe; Xa ipakethe efunyenweyo ineTag, ipakethi iya kufunyanwa ukuba i-ID yeVLAN ivunyelwe i-VLAN ID yezibuko. Xa i-ID ye-VLAN ayivumelekanga i-ID ye-VLAN ye-port, ipakethi iya kulahlwa. Xa uthumela ipakethi, xa i-ID yeVLAN ifana ne-ID ye-VLAN engagqibekanga, susa iTag kwaye uthumele ipakethi. Xa i-ID ye-VLAN yahlukile kwi-ID ye-VLAN engagqibekanga, gcina iTag yoqobo kwaye uthumele ipakethi.
3. I-Hybrid port: Ukusebenza xa ufumana ipakethi kuyafana nokusebenza kwe-Trunk port. Xa uthumela ipakethe, xa i-ID ye-VLAN ethwelwe kwipakethi yi-ID ye-VLAN evunyelwe yi-port, ipakethe iyathunyelwa, kwaye ungaqwalasela ukuba izibuko liphethe iTag xa uthumela ipakethe ye-VLAN (kubandakanya i-VLAN engagqibekanga) ngomyalelo.
Lo mzobo ulandelayo ubonisa i-EPON yethu ye-HDV 8pon portOLT
I-EPON yethu ye-HDV 8pon portOLTukuqwalasela okumiselweyo komyalelo we-vlan kwizibuko ngulo: izibuko elingagqibekanga-vlan 100.
Umyalelo wokongeza izibuko kwi vlan ehambelanayo ngulo: vlan hybrid 100 untagged. Ungathatha indawo ye-hybrid kunye nokufikelela kunye ne-trunk, kwaye ungaphawulwanga ngethegi, kuxhomekeke kwiimfuno zakho.
