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.

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, use 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.

Restrictions and guidelines

When you configure Layer 2 link aggregation in an IRF fabric, follow these restrictions and guidelines:

· IRF physical ports must be set to the bridge mode.

· When you bind physical ports to an IRF port, you must set all the physical ports to operate in either normal or enhanced mode.

· The physical ports of two connected IRF ports must operate in the same mode: normal or enhanced. For more information about the binding mode of the IRF physical ports, see IRF Configuration Guide.

· 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:

Procedures

1. Configure IRF on Device A:

# Shut down GigabitEthernet 1/0/1.

<DeviceA> system-view

[DeviceA] interface gigabitethernet 1/0/1

[DeviceA-GigabitEthernet1/0/1] shutdown

[DeviceA] irf-port 1/1

[DeviceA-irf-port1/1] port group interface gigabitethernet 1/0/1

You must perform the following tasks for a successful IRF setup:

Save the configuration after completing IRF configuration.

Execute the "irf-port-configuration active" command to activate the IRF ports.

A log message appears on Device A.

[DeviceA]%Jul 9 16:52:41:734 2016 DeviceA STM/3/STM_LINK_DOWN: IRF port 1 went down.

%Jul 9 16:52:41:800 2016 DeviceA IFNET/3/PHY_UPDOWN: Physical state on the interface GigabitEthernet1/0/1 changed to down.

Restrictions and guidelines

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, use dynamic aggregation.

If you use the S5570S-EI, S5500V3-SI, S3600V3-EI, or S3600V3-SI switch series, reserve local VLAN interface resources by using the reserve-vlan-interface command before you switch Layer 2 Ethernet interfaces to Layer 3 Ethernet interfaces or create Layer 3 aggregate interfaces. For more information about VLAN interface resource reservation, see the VLAN configuration and commands for the products.

Restrictions and guidelines

You can set the global or group-specific load sharing mode. A link aggregation group preferentially uses the group-specific load sharing mode. If the group-specific load sharing mode is not available, the group uses the global load sharing mode. This example uses group-specific load sharing mode configuration.
