# Configure port GigabitEthernet 3/0/3 as a trunk port, and assign it to VLANs 100 and 200,
thus enabling GigabitEthernet 3/0/3 to forward traffic of VLANs 100 and 200 to Device B.
[DeviceA] interface gigabitethernet 3/0/3
[DeviceA-GigabitEthernet3/0/3] port link-type trunk
[DeviceA-GigabitEthernet3/0/3] port trunk permit vlan 100 200
Please wait... Done.
2. Configure Device B in the same way Device A is configured.
3. Configure Host A and Host C to be on the same network segment, 192.168.100.0/24 for
example. Configure Host B and Host D to be on the same network segment, 192.168.200.0/24
for example
Verifying the configuration
1. Host A and Host C can ping each other successfully, but they both fail to ping Host B. Host B and
Host D can ping each other successfully, but they both fail to ping Host A.
2. Check whether the configuration is successful by displaying relevant VLAN information.
# Display information about VLANs 100 and 200 on Device A:
[DeviceA-GigabitEthernet3/0/3] display vlan 100
VLAN ID: 100
VLAN Type: static
Route Interface: not configured
Description: VLAN 0100
Name: VLAN 0100

[DeviceA-GigabitEthernet3/0/3] display vlan 200
VLAN ID: 200
VLAN Type: static
Route Interface: not configured
Description: VLAN 0200
Name: VLAN 0200
Broadcast MAX-ratio: 100%

Configuring MAC-based VLANs
Introduction to MAC-based VLAN
The MAC-based VLAN feature assigns hosts to a VLAN based on their MAC addresses. This feature is
mostly used in conjunction with security technologies such as 802.1X to provide secure, flexible network
access for terminal devices.
