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 Avaya P330 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. LAGs also provide 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.)

Note: In the P330-ML switches you need to erase all ports in t.he LAG in order to remove it.
