Layer 2 static aggregation configuration example

On the network shown in Figure 12, 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.

1. Configure Device A:

   # Create VLAN 10, and assign port Ten-GigabitEthernet 1/0/4 to VLAN 10.

   <DeviceA> system-view
   [DeviceA] vlan 10
   [DeviceA-vlan10] port ten-gigabitethernet 1/0/4
   [DeviceA-vlan10] quit
   

   # Create VLAN 20, and assign port Ten-GigabitEthernet 1/0/5 to VLAN 20.

   [DeviceA] vlan 20
   [DeviceA-vlan20] port ten-gigabitethernet 1/0/5
   [DeviceA-vlan20] quit
   

   # Create Layer 2 aggregate interface Bridge-Aggregation 1.

   [DeviceA] interface bridge-aggregation 1
   [DeviceA-Bridge-Aggregation1] quit
   

   # Assign ports Ten-GigabitEthernet 1/0/1 through Ten-GigabitEthernet 1/0/3 to link aggregation group 1.

   [DeviceA] interface ten-gigabitethernet 1/0/1
   [DeviceA-Ten-GigabitEthernet1/0/1] port link-aggregation group 1
   [DeviceA-Ten-GigabitEthernet1/0/1] quit
   [DeviceA] interface ten-gigabitethernet 1/0/2
   [DeviceA-Ten-GigabitEthernet1/0/2] port link-aggregation group 1
   [DeviceA-Ten-GigabitEthernet1/0/2] quit
   [DeviceA] interface ten-gigabitethernet 1/0/3
   [DeviceA-Ten-GigabitEthernet1/0/3] port link-aggregation group 1
   [DeviceA-Ten-GigabitEthernet1/0/3] 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.)

# 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, * -- Management port
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: Shar
Management VLAN : None
  Port               Status  Priority Oper-Key
--------------------------------------------------------------------------------
  XGE1/0/1           S       32768    1
  XGE1/0/2           S       32768    1
  XGE1/0/3           S       32768    1

The output shows that:

• Link aggregation group 1 is a Layer 2 static aggregation group.

• The aggregation group contains three Selected ports.
