Layer 2 static aggregation configuration example
Network requirements
On the network shown in Figure 6, perform the following tasks:
Configure a Layer 2 static aggregation group on both Device A and Device B.
Enable VLAN 10 at one end of the aggregate link to communicate with VLAN 10 at the other end.
Enable VLAN 20 at one end of the aggregate link to communicate with VLAN 20 at the other end.

Configuration procedure
Configure Device A:
# Create VLAN 10, and assign port GigabitEthernet 2/1/4 to VLAN 10.
<DeviceA> system-view [DeviceA] vlan 10 [DeviceA-vlan10] port gigabitethernet 2/1/4 [DeviceA-vlan10] quit
# Create VLAN 20, and assign port GigabitEthernet 2/1/5 to VLAN 20.
[DeviceA] vlan 20 [DeviceA-vlan20] port gigabitethernet 2/1/5 [DeviceA-vlan20] quit
# Create Layer 2 aggregate interface Bridge-Aggregation 1.
[DeviceA] interface bridge-aggregation 1 [DeviceA-Bridge-Aggregation1] quit
# Assign ports GigabitEthernet 2/1/1 through GigabitEthernet 2/1/3 to link aggregation group 1.
[DeviceA] interface gigabitethernet 2/1/1 [DeviceA-GigabitEthernet2/1/1] port link-aggregation group 1 [DeviceA-GigabitEthernet2/1/1] quit [DeviceA] interface gigabitethernet 2/1/2 [DeviceA-GigabitEthernet2/1/2] port link-aggregation group 1 [DeviceA-GigabitEthernet2/1/2] quit [DeviceA] interface gigabitethernet 2/1/3 [DeviceA-GigabitEthernet2/1/3] port link-aggregation group 1 [DeviceA-GigabitEthernet2/1/3] quit
# Configure Layer 2 aggregate interface Bridge-Aggregation 1 as a trunk port and assign it to VLANs 10 and 20.
[DeviceA] interface bridge-aggregation 1 [DeviceA-Bridge-Aggregation1] port link-type trunk [DeviceA-Bridge-Aggregation1] port trunk permit vlan 10 20 [DeviceA-Bridge-Aggregation1] quit
Configure Device B in the same way Device A is configured. (Details not shown.)
Verifying the configuration
# Display detailed information about all aggregation groups on Device A.
[DeviceA] display link-aggregation verbose Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing Port Status: S -- Selected, U -- Unselected, I -- Individual Flags: A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation, D -- Synchronization, E -- Collecting, F -- Distributing, G -- Defaulted, H -- Expired Aggregate Interface: Bridge-Aggregation1 Aggregation Mode: Static Loadsharing Type: NonS Port Status Priority Oper-Key -------------------------------------------------------------------------------- GE2/1/1 S 32768 1 GE2/1/2 S 32768 1 GE2/1/3 S 32768 1
The output shows that link aggregation group 1 is a Layer 2 static aggregation group that contains three Selected ports.
