PACKET Tracer Learning Network through Cisco simulator Cisco 3--Initial understanding of VLANs

VLAN, the virtual LAN (Virtul local area network), the VLAN divides the physical connected LAN logic into different virtual networks, its existence can reduce the broadcast domain, enhance the network security and convenient and flexible networking

, adding PCs and switches

By configuring VLANs, you can implement PC1 and PC2 that are connected to the same switch and cannot communicate, even though they are under the same network segment

2 Enter SWITCH1, configure Port VLAN

Switch2 same, and switch1 configuration same here no longer repeat

3 Validation Actions

Enter PC1, ping command

This configuration also shows that if the VLAN configuration is incorrect may cause the device to not properly access the other network, later encounter similar problems can be considered is not a VLAN configuration problem
