Configuration consideration
 Create VLANs 100 and 200.
 Configure the uplink ports of Device A and Device C as trunk ports, and assign them to VLANs 100
and 200.
 Configure the downlink ports of Device B as trunk ports, and assign them to VLANs 100 and 200.
Configure the uplink ports of Device B as access ports connecting to the servers respectively, and
assign them to VLANs 100 and 200 respectively.
 Associate the MAC address of Laptop 1 with VLAN 100, and associate the MAC address of Laptop
2 with VLAN 200.
Configuration procedure
1. Configure Device A.
# Create VLANs 100 and 200.
<DeviceA> system-view
[DeviceA] vlan 100
[DeviceA-vlan100] quit
[DeviceA] vlan 200
[DeviceA-vlan200] quit
# Associate the MAC address of Laptop 1 with VLAN 100, and associate the MAC address of Laptop 2
with VLAN 200.
[DeviceA] mac-vlan mac-address 000d-88f8-4e71 vlan 100
[DeviceA] mac-vlan mac-address 0014-222c-aa69 vlan 200
# Configure Laptop 1 and Laptop 2 to access the network through GigabitEthernet 1/0/1. Configure
GigabitEthernet 1/0/1 as a hybrid port that sends packets of VLANs 100 and 200 untagged, and
enable MAC-based VLAN on it.
