Configuration procedure
The following configuration is used for Switch A. Configure Switch B in a similar way.
1 Enter port view of GigabitEthernet1/0/1.
[4200G] interface GigabitEthernet1/0/1
2 Set GigabitEthernet1/0/1 as a trunk port and allow the packets of VLAN 2, VLAN 6
through VLAN 50 and VLAN 100 to pass the port.
[4200G-GigabitEthernet1/0/1] port link-type trunk
[4200G-GigabitEthernet1/0/1] port trunk permit vlan 2 6 to 50 100
3 Create VLAN 100.
[4200G] vlan 100
4 Configure the default VLAN ID of GigabitEthernet1/0/1 as 100.
[4200G-GigabitEthernet1/0/1] port trunk pvid vlan 100
Symptom: Default VLAN ID configuration failed.
Solution: Take the following steps.
1 Use the display interface or display port command to check if the port is a trunk
port or a hybrid port. If not, configure it as a trunk port or a hybrid port.
2 Configure the default VLAN ID.
Switch A
Switch B
