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.
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 HundredGigE 1/0/1 to its aggregation group.
2. Assign the aggregate interfaces to the same DR group.
Applicable hardware and software versions
The following matrix shows the hardware and software versions to which this configuration example is applicable:
Hardware |
Software version |
S6850 switch series S9850 switch series |
Release 6555P01 |
S9820-64H switch |
Release 6555P01 |
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.
