فيديو شرح VLANs: Am I a joke to you? // Python VLAN hacking. ضمن كورس اختبار اختراق الشبكات شرح قناة David Bombal، الفديو رقم 3 مجانى معتمد اونلاين
Dynamic Trunking Protocol (DTP) makes it easy to sniff traffic from other VLANs. Disable DTP on user facing ports by making those ports access ports.
You need to learn to code! Learn Python. Learn Networking. You are going to be very powerful and very scary if you combine knowledge of networking with Python scripting! But, do good.
Learn to code. Learn Linux. Learn Networking.

Cisco Best practice:
Access ports (for vlan 2 in this case):
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 2
Trunk ports:
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport trunk encapsulation dot1q
Switch(config-if)# switchport nonegotiate
