Link Aggregation Group (LAG)

LAG Overview

A LAG uses multiple ports to create a high bandwidth connection with another
device.
For example, assigning four 100Base-T ports to a LAG on an W310
allows the switch to communicate at an effective rate of 400 Mbps with another
switch.
LAGs provide
• a cost-effective method for creating a high bandwidth connection.
• built-in redundancy for the ports that belong to a LAG. If a port in a LAG fails, its traffic
is directed to another port within the LAG.
The behavior of the LAG is derived from the base port (the first port that becomes a LAG
member). The attributes of the base port, such as port speed, VLAN number, etc., are applied
to all the other member ports in the LAG.
When created, each LAG is automatically assigned a logical port number (usually
designated 10x). This logical port number can then be used as any regular panel
port for all configuration required for the LAG (Spanning Tree, Redundancy, etc.)
In the W310, you need to erase all ports in the LAG in order to remove it.
