Layer 3 static aggregation configuration example
Network requirements
On the network shown in Figure 10, perform the following tasks:
Configure a Layer 3 static aggregation group on both Device A and Device B.
Configure IP addresses and subnet masks for the corresponding Layer 3 aggregate interfaces.

Configuration procedure
Configure Device A:
# Create Layer 3 aggregate interface Route-Aggregation 1, and configure an IP address and subnet mask for the aggregate interface.
<DeviceA> system-view [DeviceA] interface route-aggregation 1 [DeviceA-Route-Aggregation1] ip address 192.168.1.1 24 [DeviceA-Route-Aggregation1] quit
# Assign Layer 3 Ethernet interfaces GigabitEthernet 2/1/1 through GigabitEthernet 2/1/3 to 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 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: Route-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 3 static aggregation group that contains three Selected ports.
