Aggregation Overview

When using LAGs between two switches, as shown in Figure

depends on how many physical ports are included.

LAGs are also useful for connecting a G8264CS to third‐party devices that support

link aggregation, such as Cisco routers and switches with EtherChannel

technology (not ISL aggregation technology) and Sunʹs Quad Fast Ethernet

Adapter. LAG technology is compatible with these devices when they are

configured manually.

LAG traffic is statistically distributed among the ports in a LAG, based on a variety

of configurable options.

Also, since each LAG is comprised of multiple physical links, the LAG is inherently

fault tolerant. As long as one connection between the switches is available, the

trunk remains active and statistical load balancing is maintained whenever a port

in a LAG is lost or returned to service.
