Understanding Packet-Switching Modes (Routers and Multilayer Switches)
In addition to the high CPU utilization issues previously discussed, a router’s packet-switching mode can impact router performance. Before discussing the most common switching modes, realize that the way a router handles packets (or is capable of handling packets) largely depends on the router’s architecture. Therefore, for real-world troubleshooting, consult the documentation for your router to determine how it implements packet switching.
In general, however, Cisco routers and multilayer switches support the following three primary modes of packet switching:
