Introduction
This document provides Ethernet link aggregation configuration examples.
Prerequisites
The configuration examples in this document were created and verified in a lab environment, and all the
devices were started with the factory default configuration. When you are working on a live network,
make sure you understand the potential impact of every command on your network.
This document assumes that you have basic knowledge of Ethernet link aggregation.
Example: Configuring Layer 2 link aggregation
Network requirements
As shown in
, both Device A and Device B forward traffic from VLAN 10 and VLAN 20.
Configure link aggregation on Device A and Device B to meet the following requirements:
•
VLAN 10 on Device A can communicate with VLAN 10 on Device B.
•
VLAN 20 on Device A can communicate with VLAN 20 on Device B.

Requirements analysis
To enable traffic from VLAN 10 and VLAN 20 to pass through Layer 2 aggregate interface
Bridge-aggregation 1, perform the following tasks:
•
Configure Layer 2 aggregate interface Bridge-aggregation 1 as a trunk port.
•
Assign the aggregate interface to VLAN 10 and VLAN 20.
