# Configure the link aggregation mode as dynamic.

[DeviceA-Route-Aggregation1] link-aggregation mode dynamic

# Configure an IP address and subnet mask for 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

2. Configure Device B in the same way Device A is configured.

Verifying the configuration

# Display detailed information about all aggregation groups on Device A.
