LAG Management Configuration on SFE / SGE Stackable Managed Switches

Objective

A Link Aggregate Group (LAG) is used to link multiple ports together. LAGs multiply bandwidth, increase port flexibility, and provides link redundancy between two devices to optimize port usage. A static LAG allows for up to eight ports and has LACP disabled. The group of ports on a static LAG are always active members. A dynamic LAG allows for up to 16 ports and has LACP enabled. The group of ports on a dynamic LAG are candidate ports. LACP determines which eight candidate ports will become active ports.

This article explains how to configure LAGs and LAG membership on the SFE / SGE Stackable Managed Switches.

Applicable Devices

• SFE / SGE Stackable Managed Switches

Software Version

• v3.0.2.0

LAG Management

Step 1. Log in to the Switch Configuration Utility and choose Bridging > Port Management > LAG Management. The LAG Management page opens:

Step 2. Click Edit to edit a LAG. The Edit LAG Membership window appears:

Step 3. (Optional) From the LAG drop-down list choose the LAG you want to configure.

Step 4. Enter a name for the LAG in the LAG Name field.

Step 5. Check LACP to enable Link Aggregation Control Protocol (LACP) on the LAG. LACP allows the LAG to have up to 16 ports and determines which 8 will be in use.

Note: LACP can only be enabled before ports are added to the LAG.

Step 6. Choose the ports that you would like to add to the LAG in the Port List field.

Step 7. Click >> to make the specified ports members of the LAG.

Step 8. Click Apply.

Caution: This only saves your configuration to the running configuration file. This means any changes made will be lost if the device is rebooted. If you wish to save these changes even after a system reboot, you need to copy the running configuration file to the startup configuration file. See Copy Configuration File on SFE/SGE Series Managed Switches for more information on how to do this.
