Cisco Etherchannel Overview and how it can be configured in Cisco Catalyst Switches – Series 1

Yasir Irfan — Mon, 15 Dec 2008 06:55:35 +0000

Dear Friends in this upcoming series of posts I would like to concentrate on Etherchannel , what is Etherchannel? , what rules and restrictions are applied to an Etherchannel and finally I will show you how to configure an Etherchannel in Cisco Switches both layer 2 as well as layer 3.

An Etherchannel combines multiple physical links into a single logical link that provides aggregate bandwidth of 800 MBPS (fast Etherchannel, full duplex) , 8 GBPS (Giga Etherchannel) or 80 Gbps (10 Giga Ethernet) . Ideal for load sharing or link redundancy – can be used by both layer 2 and Layer 3 subsystems and Etherchannel can provide network managers with a reliable, high-speed solution for the campus network backbone. EtherChannel technology was invented by Kalpana in the early 1990s. They were later acquired by Cisco Systems in 1994. In 2000 the IEEE passed 802.3ad which is an open standard version of EtherChannel.

I would like to explain some key points about Etherchannel using graphical diagrams so that it’s easy understand and to remember.

Etherchannel can be configured defined on Ethernet, Fast Ethernet, Giga Ethernet or 10 Giga Ethernet ports.
