15.5.3 Typical Application of the Dynamic VLAN

Scenario:

In the office network Department A belongs to VLAN100. Several members of this department often have the

need to move within the whole office network. It is also required to ensure the resource for other members of

the department to access VLAN 100. Assume one of the members is M, the MAC address of his PC is

00-30-4f-11-22-33, when M moves to VLAN200 or VLAN300, the port connecting M is configured as Hybrid

mode and belongs to VLAN100 with untag mode. In this way, the data of VLAN100 will be forwarded to the

port connecting M, and implement the communication requirement in VLAN100.
