Dear Friends, hope everyone is having great holidays, have fun. In my previous post  I was focusing on some of the limitations of Etherchannel. Now let’s proceed a step ahead and figure out about the Etherchannel negotiation protocols. Etherchannels can be negotiated between two Cisco Catalyst Switches  to provide some dynamic link configuration.

 Basically there are two types of protocols are available, which can be used to bundled the automated creation of an Etherchannel in the Cisco Catalyst Switches.

In upcomming post I will try to concentrate on automating the creation of an Etherchannel . Have fun and happy new year 2009.

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.
