WebNov 17, 2024 · NOTE. CEF is also supported on all Cisco routers from IOS 12.0 upwards. It is important to understand that the CEF implementation on low-end routers (i.e., Cisco 3700 series and lower) still uses the main processor for data plane operations, whereas L3 switches use a dedicated hardware chip (ASIC) for data plane operations (e.g., PFC-2) … WebCisco Express Forwarding (CEF) is an advanced layer 3 switching technology used mainly in large core networks or the Internet to enhance the overall network performance. … WebMar 6, 2024 · Reply. CEF stands for Cisco Express Forwarding and is a type of switching used in high-performance routers. It uses a combination of hardware and software to make sure packets are switched quickly and efficiently, reducing network latency.
