How to create a Port Channel/LACP/Link Aggregation on cnMatrix Switches

This article describes how to create a Port Channel (also called Link Aggregation or LACP) on cnMatrix Switches using cnMaestro, XMS-Cloud or the Command Line Interface (CLI).


  1. Login to cnMaestro


  2. Navigate to Switch Groups by clicking the Switch Groups icon in the menu on the left side of the page.


  3. Select the Switch Group that the Switch you wish to add the Port Channel to


  4. Select the Switch Ports option


  5. Mark the tick box for the ports you wish to create the Port Channel on and click ‘Create Port Channel’

  6. Enter in the Port Channel number (any number between 1 and 65535 that isn’t already in use on the Switch), select Active or Passive mode and click Create


  7. Once created, Sync the configuration by navigating the Menu system on the left and selecting Administration > Sync Configuration


  8. Tick the box of the Switch you wish to Sync the configuration and click ‘Sync Now’


  1. Login to XMS-Cloud


  2. Navigate to the Switches tab

  3. Click the empty space between Hostname and Model (any empty space on the same line will work) to bring up the Switch ports

  4. Hover over and select the Switch ports you wish to aggregate


  5. Ensure multiple ports are selected (notice it showing Port 5 and Port 7 in the example) and click the Actions drop down

    You may find you aren’t able to edit the Ports as they are in Read-Only mode. To change this, click the Administrator name in the top right, select Settings and scroll down to the bottom of the My Account page. Here you will find a slider that will allow you to change from Read-Only to Editable.


  6. Select ‘Combine Ports’ to create the Port Channel


  7. Ensure all settings are the same on both ports and Select Save Port Channel

cnMatrix CLI

  1. Login to the Switch via SSH or Console using an terminal application such as PuTTy


  2. Run the below commands

    conf t
    interface port-channel <number>
    no shut
    interface gigabitethernet 0/<num>
    channel-group <num> mode <active/passive>
    interface gigabitethernet 0/<num>
    channel-group <num> mode <active/passive>

    Here’s an example below, using 5 for the port channel number and selecting interface gigabit ethernet 9 & 10. You can change these numbers and interfaces to suit your needs.


  3. Save the configuration by going back to terminal mode and typing

    copy running-config startup-config
