Etherchannels and Link Aggregation Protocols – Chapter Summary

The following section is a summary of the major points you should be aware of in this chapter.
Understanding EtherChannels

• An EtherChannel is comprised of physical, individual Fast, Gigabit, or 10Gbps links
• The links in an EtherChannel appear as a single logical link
• Each EtherChannel can consist of up to eight (8) ports
• Physical links in an EtherChannel must share similar characteristics
