Step 1: Configuration of Switches C and D.

Switches C and D use VLAN Trunk uplink to link to Switches A and B.

PC1 and 2 connect to Switches C and D.

From the application, we can create VLAN100 for port1 as Access Port and Port7 for Trunk Uplink.

Please follow the instructions below:

1. Creating VLAN100.

   èCreate VLAN. 

   èFill out the VLAN List 2 and VLAN Name QinQ .

   èPress the Apply button. 

   èThe configuration will show in the VLAN table.

2. Making GE7 as Trunk port with PVID2 and changing Uplink Status as Enable and TPID 88a8. 

   èVLAN.
