Configuring Port Groups and VLAN20 on Huawei Switches
This guide explains how to create a permanent port group on a Huawei aggregation switch, add ten access‑switch interfaces to it, set the ports as trunk, allow VLAN20 traffic, and verify the configuration using display commands.
The network diagram shows an aggregation switch with 30 downstream access switches, of which ten need to interconnect and permit VLAN20 traffic. To achieve this, the aggregation switch ports GE1/0/1 through GE1/0/10 must be configured to allow VLAN20.
First, create a permanent port group on the Huawei switch:
port-group 1 // create port group 1
Add the required interfaces to the group:
group-member gigabitethernet1/0/1 to gigabitethernet1/0/10 // add GE1/0/1‑GE1/0/10 to port group 1
Set the port type to trunk and allow VLAN20 to pass:
port link-type trunk // configure port as trunk
port trunk allow-pass vlan20 // allow VLAN20 on the trunk ports
Verify the permanent port group members with the display command:
displayport-group [all|port-group-name] // view members of the specified port group
For temporary port groups, the following command can be used, which is equivalent to an interface range command:
port-group group-member gigabitethernet1/0/1 to gigabitethernet1/0/10 // create temporary port group
Equivalent command:
interface range gigabitethernet1/0/1 to gigabitethernet1/0/10 // select the range of interfaces
