Layer 3 edge aggregate interface configuration example
Network requirements
As shown in Figure 13, a Layer 3 dynamic aggregation group is configured on the device. The server is not configured with dynamic link aggregation.
Configure an edge aggregate interface so that both GigabitEthernet 2/1/1 and GigabitEthernet 2/1/2 can forward traffic to improve link reliability.

Configuration procedure
# Create Layer 3 aggregate interface Route-Aggregation 1, and set the link aggregation mode to dynamic.
<Device> system-view [Device] interface route-aggregation 1 [Device-Route-Aggregation1] link-aggregation mode dynamic
# Configure an IP address and subnet mask for Layer 3 aggregate interface Route-Aggregation 1.
[Device-Route-Aggregation1] ip address 192.168.1.1 24
# Configure Layer 3 aggregate interface Route-Aggregation 1 as an edge aggregate interface.
[Device-Route-Aggregation1] lacp edge-port [Device-Route-Aggregation1] quit
# Assign Layer 3 Ethernet interfaces GigabitEthernet 2/1/1 and GigabitEthernet 2/1/2 to aggregation group 1.
[Device] interface gigabitethernet 2/1/1 [Device-GigabitEthernet2/1/1] port link-aggregation group 1 [Device-GigabitEthernet2/1/1] quit [Device] interface gigabitethernet 2/1/2 [Device-GigabitEthernet2/1/2] port link-aggregation group 1 [Device-GigabitEthernet2/1/2] quit
Verifying the configuration
# Display detailed information about all aggregation groups on the device when the server is not configured with dynamic link aggregation.

The output shows that GigabitEthernet 2/1/1 and GigabitEthernet 2/1/2 are in Individual state when they do not receive LACPDUs from the server. Both GigabitEthernet 2/1/1 and GigabitEthernet 2/1/2 can forward traffic. When one port fails, its traffic is automatically switched to the other port.
