I. Tutorial Purpose

SW1's G0/1 G0/2 interfaces are all hybrid ports. G0/1 belongs to VLAN 2, while G0/2 belongs to VLAN 3. What configurations do you need to add to connect two PCs?

Analysis

PC1 sends a packet. the destination address is PC2, And the G0/1 interface of SW1 is the hybrid port. It tags the pC1 packet with VLAN 2 and receives the packet. G0/2 belongs to VLAN 3, all pC1 and PC2 cannot communicate with each other. Now, add a configuration in the G0/1 interface of SW1, allowing VLAN 3 to pass through without tags, add a packet that allows VLAN 2 to pass the test without a tag.

 

PC1 sends a data packet with the target address PC2 and SW1's G0/1 interface as the hybrid port, and receives the data packet with the label of VLAN 2, the G0/2 interface allows packets of VLAN 2 to pass through without tags. Therefore, packets of pC1 are sent without tags on the G0/2 interface of sw2, and PC2 receives

 

Back package:

PC2 replies to a data packet. the destination address is pC1, and SW1's G0/2 interface is the hybrid port, which is tagged with VLAN 3 for receiving data packets, the G0/1 interface allows packets of VLAN 3 to pass through without tags. Therefore, packets of Pc2 are sent without tags on the G0/1 interface of sw2, and pC1 receives

 

Therefore, pC1 can communicate with pc2.
