2.4.6 Example for configuring VLAN mapping
Networking requirements
As shown in Figure 2-7, Port 2 and Port 3 of Switch A are connected to Department E of
VLAN 100 and Department F of VLAN 200, Port 2 and Port 3 of Switch B are connected to
Department C of VLAN 100 and Department D of VLAN 200. The ISP assigns VLAN 1000
to transmit packets of Department E and Department C, and VLAN 2008 to transmit packets
of Department F and Department D.
Configure 1:1 VLAN mapping on the Switch A and Switch B to implement normal
communication between PC or terminal users and servers.
