Fast Etherchannel (FEC) is a proprietary technology developed by Cisco. With FEC, you can create a team of two to four ports on the Quad-port 10/100 Ethernet PCI Adapter in to increase transmission and reception throughput. This feature may also be referred to as load balancing, port aggregation, or trunking. When you configure this feature, the adapter ports comprising the FEC team or group create a single high-speed, fault-tolerant link between the engine and the Ethernet switch sharing one IP address. With FEC, fault tolerance and load balancing is provided for both outbound and inbound traffic, unlike other load balancing schemes that only balance outbound traffic.

FEC requires an Ethernet switch with FEC capability. The FEC implementation on the Quad-port 10/100 Ethernet Adapter does not support the optional Port Aggregation Protocol (PAgP) feature of FEC-capable Ethernet switches.
