How is debug traffic processed on a Cisco IOS router when the packets are generated by the router out its local interfaces?
- Cisco Express Forwarding switched
- fast-switched
- ASIC-switched
- process-switched
Explanation: Packets that are generated by a router or destined for a router are handled directly by the router's processor and are therefore process-switched. Because they are processed in this manner, they can be captured and displayed by diagnostic commands like debug ip packet. In contrast, packets that are merely forwarded through a router using hardware-accelerated methods like Cisco Express Forwarding (CEF) or fast-switching are not sent to the CPU and will not appear in debug output unless those switching features are specifically disabled.
