EtherChannel Insights

What is EtherChannel?

EtherChannel is a port aggregation technology or port trunking technology that allows multiple physical Ethernet links to be combined into one logical link. It is commonly used to increase bandwidth between network devices, such as switches or routers, and to provide link redundancy. If one link in the EtherChannel fails, traffic is automatically redistributed across the remaining active links.
