Abstract
This invention includes tools that prevent forwarding of a packet to a control plane of a packet switch. The tools receive a packet comprising indicia suggesting that the packet be forwarded to a control plane of a packet switch. After receiving the packet, the tools may modify the packet to prevent the packet from being forwarded to the control plane, intercept the packet before it is received by the control plane, or otherwise prevent the packet from being forwarded to the control plane. The tools may also forward the packet from a source port of a packet switch to a destination port of the packet switch without forwarding the packet to the control plane of the packet switch.
