What are some of the differences between how process-switched packets and CEF or fastswitched packets are handled during ATM processing on the Cisco 7200 series router?
Process-switched packets are stored in the public normal pool on the NPE or NSE rather than the private interface pool, where CEF and fastswitched packets are stored. Process-switched packets automatically enqueue to the Layer 3 queue, regardless of whether the transmit ring has available entries. Therefore, Layer 3 queueing is always active for process-switched packets. The transmit ring must be full (no more ring entries available) for CEF and fastswitched packets to enqueue to their corresponding Layer 3 queues.
