Ethernet Port Configuration Example 
Network requirements 
As shown in 
z 
Switch A is connected to Switch B through trunk port GigabitEthernet 1/0/1.  
z 
Configure the default VLAN ID for the trunk port as 100.  
z 
Allow the packets of VLAN 2, VLAN 6 through VLAN 50 and VLAN 100 to pass the port.  
Figure 1-1 Network diagram for default VLAN ID configuration 
 
 
Configuration procedure 
The following configuration is used for Switch A. Configure Switch B in a similar way.  
# Enter port view of GigabitEthernet 1/0/1.  
[device] interface GigabitEthernet1/0/1 
# Set GigabitEthernet 1/0/1 as a trunk port and allow the packets of VLAN 2, VLAN 6 through VLAN 50 
and VLAN 100 to pass the port.  
[device-GigabitEthernet1/0/1] port link-type trunk 
[device-GigabitEthernet1/0/1] port trunk permit vlan 2 6 to 50 100 
# Create VLAN 100.
