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 configuration

As shown in Figure 1, 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.

Figure 1 Network diagram

 

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.

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware	Software version
S6550X-HI switch series	Release 1116 and later
S6880 switch series	Release 1116 and later
S9820-8M switch	Release 1116 and later
S9855 switch series	Release 9126 and later
S9825 switch series	Release 9126 and later

 

Restrictions and guidelines

When you configure Layer 2 link aggregation, follow these restrictions and guidelines:

·     When you assign a port to an aggregation group, the recommended configuration procedure is as follows:

a.     Use the display this command in interface view to check the following attribute configurations of the port:

-     Port isolation.

-     QinQ.

-     VLAN.

-     VLAN mapping.

b.     If any of the above configurations exist, use the undo forms of the corresponding commands to remove these configurations. This enables the port to use the default attribute configurations.

c.     Assign the port to the aggregation group.

·     In a static aggregation group, the Selected state of a port is not affected by whether the peer port is added to an aggregation group and is Selected. As a result, the Selected state of a port might be different from the Selected state of the peer port. When both ends support static aggregation and dynamic aggregation, HP recommends using dynamic aggregation.

·     You cannot assign a port to a Layer 2 aggregation group when MAC authentication, port security mode, or 802.1X is configured or enabled on the port.

Procedures

1.     Configure Device A:

# Create VLAN 10, and assign port Twenty-FiveGigE 1/0/4 to VLAN 10.

Network configuration

As shown in Figure 2, 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.

·     The packets from VLAN 10 are load shared across the Selected ports of link aggregation group 1 by source MAC addresses. The packets from VLAN 20 are load shared across the Selected ports of link aggregation group 2 by source MAC addresses.

Analysis

To enable packets from VLAN 10 to pass through aggregate interface Bridge-aggregation 1, assign the aggregate interface to VLAN 10. To enable packets from VLAN 20 to pass through aggregate interface Bridge-aggregation 2, assign the aggregate interface to VLAN 20.
