Cisco EtherChannel Overview
Cisco EtherChannel technology builds upon standards-based 802.3 full-duplex Fast Ethernet to provide
network managers with a reliable, high-speed solution for the campus network backbone. EtherChannel
technology provides bandwidth scalability within the campus by providing up to 800 Mbps, 8 Gbps, or 80
Gbps of aggregate bandwidth for a Fast EtherChannel, Gigabit EtherChannel, or 10 Gigabit EtherChannel
connection, respectively. Each of these connection speeds can vary in amounts equal to the speed of the links
used (100 Mbps, 1 Gbps, or 10 Gbps). Even in the most bandwidth-demanding situations, EtherChannel
technology helps to aggregate traffic, keeps oversubscription to a minimum, and provides effective
link-resiliency mechanisms.
Cisco EtherChannel Benefits
Cisco EtherChannel technology allows network managers to provide higher bandwidth among servers, routers,
and switches than a single-link Ethernet technology can provide.
Cisco EtherChannel technology provides incremental scalable bandwidth and the following benefits:
