2.4 Ethernet Port Configuration Example
I. Network requirements
Switch A is connected to Switch B through Trunk port GigabitEthernet2/1/1. Configure
the Trunk port with default VLAN ID, so that: when receiving the packets without VLAN
Tag, the port can forward them to the member ports belonging to the default VLAN;
when it sending the packets with VLAN Tag and the packet VLAN ID is the default
VLAN ID, the Trunk port remove the packet VLAN Tag and forward the packet.

III. Configuration procedure
The following configurations are used for Switch A. Please configure Switch B in the
similar way.
# Enter the Ethernet port view of GigabitEthernet2/1/1.
[H3C] interface gigabitethernet2/1/1
# Set the GigabitEthernet2/1/1 as a trunk port and allows VLANs 2, 6 through 50, and
100 to pass.
[H3C-GigabitEthernet2/1/1] port link-type trunk
[H3C-GigabitEthernet2/1/1] port trunk permit vlan 2 6 to 50 100
# Create the VLAN 100.
[H3C] vlan 100
# Configure the default VLAN ID of GigabitEthernet2/1/1 as 100.
[H3C-GigabitEthernet2/1/1] port trunk pvid vlan 100
2.5 Ethernet Port Troubleshooting
Symptom 1: Default VLAN ID configuration fails.
Solution: Take the following steps:
Execute the display interface or display port command to check if the port is a
trunk port or a hybrid port. If it is neither of them, configure it as a trunk or hybrid
port.
Then configure the default VLAN ID.
Symptom 2: The port is in down status.
