Configuration procedure
1. Configure Device A:
# Create VLAN 100, and assign GigabitEthernet 1/0/1 to VLAN 100.
<DeviceA> system-view
[DeviceA] vlan 100
[DeviceA-vlan100] port gigabitethernet 1/0/1
[DeviceA-vlan100] quit
# Create VLAN 200, and assign GigabitEthernet 1/0/2 to VLAN 200.
[DeviceA] vlan 200
[DeviceA-vlan200] port gigabitethernet 1/0/2
[DeviceA-vlan200] quit
# Configure GigabitEthernet 1/0/3 as a trunk port to forward packets from VLANs 100 and 200
to Device B.
[DeviceA] interface gigabitethernet 1/0/3
[DeviceA-GigabitEthernet1/0/3] port link-type trunk
[DeviceA-GigabitEthernet1/0/3] port trunk permit vlan 100 200
Please wait... Done.
2. Configure Device B in the same way Device A is configured. (Details not shown.)
3. Configure hosts:
{ Configure Host A and Host C to be on the same IP subnet. For example, 192.168.100.0/24.
{ Configure Host B and Host D to be on the same IP subnet. For example, 192.168.200.0/24.
Verifying the configuration
# Verify that Host A and Host C can ping each other, but they both fail to ping Host B. (Details not
shown.)
# Verify that Host B and Host D can ping each other, but they both fail to ping Host A. (Details not
shown.)
# Verify that VLANs 100 and 200 are correctly configured on devices, for example, on Device A.
