Izilungiselelo zokucushwa kwe-VLAN yangasese ye-FS S5500-48T8SP
Izilungiselelo ze-VLAN eziyimfihlo
Kuphelileview ye-VLAN yangasese
I-VLAN Eyimfihlo ixazulule izinkinga zohlelo lokusebenza lwe-VLAN ezibhekene nama-ISP: Uma i-ISP ihlinzeka umsebenzisi ngamunye nge-VLAN, usekelo lwedivayisi ngayinye lwama-VLAN angu-4094 luzokhawulela inani labasebenzisi abasekelwa i-ISP.
Uhlobo Lwe-VLAN Yangasese kanye Nohlobo Lwembobo ku-VLAN Yangasese
I-VLAN yangasese ihlukanisa isizinda sokusakaza se-L2 se-VLAN sibe izizinda ezincane eziningi, ngasinye sazo esiqukethe ipheya ye-VLAN yangasese: i-VLAN eyinhloko kanye ne-VLAN yesibili. Isizinda esisodwa se-VLAN esiyimfihlo singase sibe namapheya amaningi e-VLAN ayimfihlo futhi ipheya ngayinye ye-VLAN eyimfihlo imele isizinda esingaphansi. Kune-VLAN eyodwa kuphela eyinhloko esizindeni se-VLAN esiyimfihlo futhi wonke amapheya e-VLAN ayimfihlo abelana nge-VLAN eyinhloko efanayo. Ama-ID wama-VLAN esibili kusizinda esingaphansi ngasinye ayahluka.
Ukuba Nohlobo Olulodwa Lwe-VLAN Eyisisekelo
I-VLAN Eyinhloko: Ihambisana nembobo engcolile futhi i-VLAN eyodwa kuphela eyinhloko ekhona ku-VLAN yangasese. Imbobo ngayinye ku-VLAN eyinhloko iyilungu le-VLAN eyinhloko.
Ukuba nezinhlobo ezimbili ze-VLAN yesibili
- I-VLAN Eyodwa: Akukho ukuxhumana kwe-layer-2 okungaqhutshwa phakathi kwamachweba amabili ku-VLAN efanayo engayodwa. Futhi, kune-VLAN eyodwa kuphela ehlukanisiwe ku-VLAN yangasese. I-VLAN ehlukanisiwe kufanele ihlobane ne-VLAN eyinhloko.
- I-VLAN yomphakathi: Ukuxhumana kwe-Layer-2 kungenziwa phakathi kwezimbobo ezimbili ku-VLAN efanayo, kodwa azinakho ukuxhumana nezimbobo kwenye i-VLAN yomphakathi. I-VLAN eyodwa yangasese ingase iqukathe ama-VLAN amaningi omphakathi. I-VLAN yomphakathi kufanele ihlobane ne-VLAN eyinhloko.
Izinhlobo Zechweba Ngaphansi Kwembobo Ye-VLAN Yangasese
- Imbobo engcolile: ingeye-VLAN eyinhloko. Ingakwazi ukuxhumana nazo zonke ezinye izimbobo, okuhlanganisa imbobo eyodwa kanye nembobo yomphakathi ye-VLAN yesibili ku-VLAN efanayo yangasese.
- Imbobo engayodwa: Imbobo yokusingatha ku-VLAN engayodwa. Ku-VLAN efanayo eyimfihlo, imbobo ehlukanisiwe ihlukaniswe ngokuphelele nge-L2 kwezinye izimbobo ngaphandle kwembobo engcolile, ngakho-ke ukugeleza okutholwe kusukela kutheku elingalodwa kungadluliselwa kuphela esikhumulweni sokuziphatha okubi.
- Imbobo yomphakathi: Kuyichweba lesikhungo emphakathini we-VLAN. Ku-VLAN yangasese, amachweba omphakathi womphakathi ofanayo we-VLAN angakwazi ukuxhumana nge-L2 yodwa noma nechweba eliziphatha kabi, kodwa hhayi nezikhumulo zomphakathi zamanye ama-VLAN kanye nezikhumulo ezingazodwa kuma-VLAN angawodwa.
Ukushintsha Izinkambu ku-VLAN TAG
Lokhu kusebenza kusekela ukuguqula i-ID ye-VLAN nokubalulekile ku-VLAN tag futhi inquma ukuthi amaphakethe e-egress e-VLAN yangasese ayayiphatha yini tag noma cha.
Uhlu Lwemisebenzi Yokucushwa Kwe-VLAN Yangasese
- Ilungiselela i-VLAN Eyimfihlo

Imisebenzi yokucushwa kwe-VLAN yangasese
Imibandela yokuthi ontanga ye-VLAN yangasese isebenze ibalwe ngezansi:
- Ukuba ne-VLAN yokuqala
- Ukuba ne-VLAN yesibili
- Ukuba nobudlelwano phakathi kwe-VLAN eyinhloko kanye ne-VLAN yesibili
- Ukuba nembobo engcolile ku-VLAN eyinhloko

Ibonisa Ulwazi Lokucushwa Kwe-VLAN Eyimfihlo
Qalisa imiyalo elandelayo kumodi yomhlaba jikelele, esibonakalayo noma ye-VLAN ukuze ubonise imininingwane yokucushwa kwe-VLAN eyimfihlo ye-VLAN eyimfihlo kanye nembobo ye-L2:
| Umyalo | Inhloso |
| bonisa i-vlan yangasese-vlan | Ibonisa ukucushwa kwe-VLAN yangasese. |

Ukucushwa Example
Ukucushwa Okujwayelekile Kwe-VLAN Yangasese
Njengoba kuboniswe emfanekisweni 1, ichweba elingu-G0/1 liyichweba elixekethile eliku-VLAN 2 eyinhloko kanye nezimbobo i-G0/2-G0/6 kuyizikhumulo zokusingatha, phakathi kwazo izimbobo i-G0/2 kanye ne-G0/3 ezingamachweba abamba (izikhumulo zomphakathi) Zomphakathi. I-VLAN 3, ichweba elingu-G0/4 ele-Community VLAN 4, futhi izimbobo i-G0/5 ne-G0/6 zingamachweba abamba i-Isolated VLAN 5.
Ngokwencazelo ye-VLAN yangasese, ukuxhumana kwe-L2 kungenziwa phakathi kwembobo engcolile ye-G0/1 namachweba abamba azo zonke izizinda ezingaphansi kwe-VLAN, ngakho-ke kuphakathi kwamachweba abamba i-G0/2 kanye ne-G0/3 yomphakathi we-VLAN 3, kodwa awakwazi. qhuba ukuxhumana kwe-L2 namanye amachweba abamba ama-VLAN esibili. Ukuxhumana kwe-L2 akukwazi ukuqhubeka phakathi kwezimbobo i-G0/5 ne-G0/6 ku-Isolated VLAN 5, kodwa lezi zimbobo zombili zingakwazi ukuqhuba ukuxhumana kwe-L2 nembobo engcolile engu-G0/1.
