VLAN trunk valós eszközön megoldása:
Sa és S2 beállítása:

Aztán a VLAN-ok:
S1(config)# vlan 10
S1(config-vlan)# name Operations
S1(config-vlan)# vlan 20
S1(config-vlan)# name Parking_Lot
S1(config-vlan)# vlan 99
S1(config-vlan)# name Management
S1(config-vlan)# vlan 1000
S1(config-vlan)# name Native
S1(config-vlan)# end
S1-PCA-val:
S1(config)# interface f0/6
S1(config-if)# switchport mode access
S1(config-if)# switchport access vlan 10
S1(config)# interface vlan 1
S1(config-if)# no ip address
S1(config-if)# interface vlan 99
S1(config-if)# ip address 192.168.1.11 255.255.255.0

S2-PCB-vel:
S2(config)# interface f0/18
S2(config-if)# switchport mode access
S2(config-if)# switchport access vlan 10
S2(config)# interface vlan 1
S2(config-if)# no ip address
S2(config-if)# interface vlan 99
S2(config-if)# ip address 192.168.1.12 255.255.255.0
Natívot:
S1(config)# interface range f0/11-24
S1(config-if-range)# switchport mode access
S1(config-if-range)# switchport access vlan 99
S1(config-if-range)# end
VLAN 10 F11-21:
S1(config)# interface range f0/11, f0/21
S1(config-if-range)# switchport access vlan 10
S1(config-if-range)# end
F24-ből kiszedni:
S1(config)# interface f0/24
S1(config-if)# no switchport access vlan
S1(config-if)# end
Aztán kiszedni a VLAN adatbázisból az ID-t:
S1(config)# interface f0/24
S1(config-if)# switchport access vlan 30
VLAN 30-at úgyahogy van törölni:
S1(config)# no vlan 30
S1(config)# end
24-es portot kiszedni VLAN-ból:
S1(config)# interface f0/24
S1(config-if)# no switchport access vlan
S1(config-if)# end
DTP módot beállítani:
S1(config)# interface f0/1
S1(config-if)# switchport mode dynamic desirable
manuálisan trönkportá adni a f/0-et:
S1(config)# interface f0/1
S1(config-if)# switchport mode trunk
S2(config)# interface f0/1
S2(config-if)# switchport mode trunk
Natívot beállítani:
S1(config)# interface f0/1
S1(config-if)# switchport trunk native vlan 1000
S2(config)# interface f0/1
S2(config-if)# switchport trunk native vlan 1000
