Configuring Port Groups and VLAN20 on Huawei Switches

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
