Configuring EtherChannels and Link-State
Tracking
This chapter describes how to configure EtherChannels on the Catalyst 2975 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. Unless otherwise noted, the term switch refers to a
standalone switch and to a switch stack.
Note For complete syntax and usage information for the commands used in this chapter, see the command
reference for this release.
