Bu faqat birinchi switchni nastroykasi. Ikkinchi Switchni ham o'zingiz nastroyka qilib shu tarmoqni Qurib @ciscoucell ga tashasangiz tekshirib beramiz.

Topologiyamizda 3 ta oiladagi ip addresslar mavjud. Endi o'ylab ko'ring 3ta oiladagi ip addresslarni har biriga alohida default-gateway berishimiz kerak. Topologiyamizdagi routerni bitta portiga butun tarmoq ulangan. Hosh bu paytio'sha portga qaysi ip addressni beramiz? Shunaqa vaziyatlarda routerda SUBINTERFACE (1ta portni logic qismlarga bo'lish)hosil qilishimiz kerak.

Tarmog'imiz tayyor eng bu holatda hamma VLANlar orasida paket o'tadi. Ikkinchi switch hamda router ulangan portni trunk qilish esingizdan chiqmasin.

🎯VLAN Tag va Untag nima?

Tag nima?

Bu Ethernet framega qo'shiladigan 4 baytlik VLAN ma'lumoti (802.1Q header).
Oddiy frame: [MAC][MAC][Type][Data]
Tagged frame: [MAC][MAC][802.1Q][Type][Data]
━━━━━━━━━━━━━━━━━━━━
ACCESS PORT 🔌
Xususiyatlari:
▫️ Faqat bitta VLAN
▫️ Tagsiz paketlar
▫️ Kompyuter, printer uchun
Ishlash prinsipi:
→ Kiruvchi paketdan tagni olib tashlaydi
→ Chiquvchi paketni tagsiz yuboradi

interface Fa0/1
switchport mode access
switchport access vlan 10

━━━━━━━━━━━━━━━━━━━━
TRUNK PORT 🚀
Xususiyatlari:
▫️ Bir nechta VLAN
▫️ Tagli paketlar
▫️ Switch-switch uchun
Ishlash prinsipi:
→ Kiruvchi: Tag borini saqlaydi
→ Chiquvchi: Kopchilik VLAN tag bilan

interface Gi0/1
switchport mode trunk
switchport trunk allowed vlan 10,20,30

━━━━━━━━━━━━━━━━━━━━
Paket oqimi misoli 📊
[PC-VLAN10] —Fa0/1— [SW1] —Gi0/1— [SW2]

1️⃣ PC tagsiz paket yuboradi
2️⃣ Access port VLAN 10 tag qoshadi
3️⃣ Trunk port tag bilan uzatadi
4️⃣ SW2 tagged paketni qabul qiladi

Kompyuterda VLAN ID o'rnatilsa nima bo'ladi? 💻
Ko'p tarmoq adapterlari VLAN taggingni qo'llab-quvvatlaydi. Lekin bu har doim kerakmi? 🤔
━━━━━━━━━━━━━━━━━━━
ACCESS PORT bilan ❌
[PC VLAN tag 10] → [Fa0/1 Access VLAN 10]
❌ Paket DROP!
Sabab: Access port faqat untagged paket kutadi, lekin tagged paket keldi!
━━━━━━━━━━━━━━━━━━━
TRUNK PORT bilan ✅
[PC VLAN tag 10] → [Gi0/1 Trunk allowed 10]
✅ VLAN 10ga yo'naladi
Shart: Trunk portda allowed vlan 10 bolishi kerak!
━━━━━━━━━━━━━━━━━━━
Xulosa 🎓
Kompyuter | Switch Port | Natija
Tag yoq | Access | ✅ Normal
Tag bor | Access | ❌ Drop
Tag bor | Trunk | ✅ Ishlaydi
━━━━━━━━━━━━━━━━━━━
Amaliy maslahat 💡
Oddiy foydalanuvchilar:
❌ VLAN tag o'rnatmang
✅ Oddiy Access portga ulang
Server/VM uchun:
✅ VLAN tagging ishlatish mumkin
✅ Trunk portga ulang
🎯 Masalan: VMware ESXi, Linux
━━━━━━━━━━━━━━━━━━━
Esda tuting! ⚠️
Kompyuterda VLAN ID yoqsangiz:
▫️ Switch TRUNK bolishi shart
▫️ Aks holda aloqa ishlamaydi
▫️ Maxsus holatlarda kerak
