21.3 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 f8-f0-82-11-22-33, 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.
