This chapter covers the following topics that you need to master for the CCNP SWITCH exam:
Switch Port Aggregation with EtherChannel—This section discusses the concept of aggregating, or “bundling,” physical ports into a single logical link. Methods for load balancing traffic across the physical links also are covered.
EtherChannel Negotiation Protocols—This section discusses two protocols that dynamically negotiate and control EtherChannels: Port Aggregation Protocol (PAgP), a Cisco proprietary protocol, and Link Aggregation Control Protocol (LACP), a standards-based protocol.
EtherChannel Configuration—This section discusses the Catalyst switch commands needed to configure EtherChannel.
