Configuration procedure
1.
Configure Device A:
# Create VLAN 100, and assign port Ethernet 1/0/1 to VLAN 100.
<DeviceA> system-view
[DeviceA] vlan 100
[DeviceA-vlan100] port ethernet 1/0/1
[DeviceA-vlan100] quit
# Create VLAN 200, and assign port Ethernet 1/0/2 to VLAN 200.
[DeviceA] vlan 200
[DeviceA-vlan200] port ethernet 1/0/2
[DeviceA-vlan200] quit
# Configure port Ethernet 1/0/3 as a trunk port, and assign it to VLANs 100 and 200, to enable
Ethernet 1/0/3 to forward traffic of VLANs 100 and 200 to Device B.
[DeviceA] interface ethernet 1/0/3
[DeviceA-Ethernet1/0/3] port link-type trunk
[DeviceA-Ethernet1/0/3] port trunk permit vlan 100 200
Please wait... Done.
2.
Configure Device B as you configure Device A.
3.
Configure Host A and Host C to be on the same IP subnet, 192.168.100.0/24, for example.
Configure Host B and Host D to be on the same IP subnet, 192.168.200.0/24, for example.
Verifying the configurations
1.
Host A and Host C and ping each other successfully, but they both fail to ping Host B. Host B and
Host D and ping each other successfully, but they both fail to ping Host A.
2.
Determine whether the configuration is successful by displaying relevant VLAN information.
# Display information about VLANs 100 and 200 on Device A.
[DeviceA-Ethernet1/0/3] display vlan 100
