NOTE: By default, all ports are member ports of the Default_VLAN. Before removing the
Deafult_VLAN from the VLAN table, make sure you have correct management VLAN and PVID
configurations, otherwise, incorrect configurations may disconnect your management PC to the
Managed Switch immediately when you enter the command.
Treatments of Packets:
1. A tagged packet arrives at Port 1
When a packet with a tag 12 arrives at Port 1, the original tag will be kept intact and then
added an outer tag 15 by Port 1, which is set as a tunnel port. When this packet is forwarded to
Port 48, two tags will be forwarded out because Port 48 is set as a trunk port.
2. A untagged packet arrives at Port 1
If an untagged packet is received, it will also be added a tag 15. However, Q-in-Q function will
not work.
