61-S-MLAG Configuration Examples	125.62 KB

Introduction

This document provides configuration examples for using simple multichassis link aggregation (S-MLAG).

S-MLAG enhances dynamic link aggregation to establish an aggregation that spans multiple standalone devices to a remote device.

Prerequisites

The configuration examples 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.

The following information is provided based on the assumption that you have basic knowledge of S-MLAG.

Example: Configuring S-MLAG

Network configuration

Device B, Device C, and Device D are standalone devices. As shown in Figure 1, configure Device B, Device C, and Device D as S-MLAG devices to establish a multidevice aggregate link with Device A.

Figure 1 Network diagram

Analysis

To establish a multidevice aggregate link with Device A, you must perform the following tasks on Device B, Device C, and Device D:

1. Create a Layer 2 dynamic aggregate interface and assign GigabitEthernet 1/0/1 to its aggregation group.

2. Assign the aggregate interfaces to the same DR group.

Restrictions and guidelines

Before you assign an interface to an aggregation group, use the display this command in interface view to identify whether attribute settings exist, including port isolation, QinQ, VLAN, and VLAN mapping settings. If attribute settings exist, use the corresponding undo commands to remove them.

Configure the link aggregation settings other than S-MLAG settings on each S-MLAG device. Make sure the settings are consistent across the S-MLAG devices.

As a best practice, maintain consistency across S-MLAG devices in service feature configuration.

Network configuration

As shown in Figure 2, configure S-MLAG as follows:

· Connect GigabitEthernet 1/0/1 interfaces on Device A, Device B, and Device C to the server, and configure S-MLAG to aggregate the links to the server.

· Configure the server-facing aggregate interfaces on Device A, Device B, and Device C as edge aggregate interfaces for the aggregation member ports to forward traffic correctly before link aggregation is set up on the server.

Restrictions and guidelines

When you configure S-MLAG, 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.

· Make sure the S-MLAG member devices have consistent link aggregation configuration.

· To ensure correct service traffic forwarding, configure the same service settings on the S-MLAG member devices.
