Understanding Etherchannels - Cisco Catalyst 2928 Software Configuration Manual

Configuring EtherChannels
This chapter describes how to configure EtherChannels on Layer 2 ports on the Catalyst 2928 switch.
EtherChannel provides fault-tolerant high-speed links between switches, routers, and servers. You can
use it to increase the bandwidth between the wiring closets and the data center, and you can deploy it
anywhere in the network where bottlenecks are likely to occur. EtherChannel provides automatic
recovery for the loss of a link by redistributing the load across the remaining links. If a link fails,
EtherChannel redirects traffic from the failed link to the remaining links in the channel without
intervention.
