Layer 2 static aggregation configuration example

Network requirements

On the network shown in Figure 6, perform the following tasks:

Configuration procedure

  1. 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
    
  2. 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.
