24 Control Plane Commands
Network control packets that are received by the switch are handled by the CPU.
This traffic can potentially overwhelm the switch CPU and impact the overall
system performance. To prevent the switch CPU from receiving too much traffic,
QoS class maps and policy maps can be defined and applied as a service policy to
ingress traffic on the CPU’s “control-plane” interface.
For details on configuring QoS class maps and policy maps, see “Quality of Service
Commands” on page 623.
