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:
