Cisco Systems 3560 사용자 설명서

This chapter describes how to configure EtherChannels on Layer 2 and Layer 3 ports on the 
Catalyst 3560 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. This chapter also describes how to configure link-state tracking. 

For complete syntax and usage information for the commands used in this chapter, see the command 
reference for this release.
