Abstract
In a pipeline network processor, a packet intercept feature determines whether a packet is to be intercepted based on the inbound and outbound port through which the packet travels and based on the source and destination of the packet. When a packet enters the pipeline network processor, a determination is made as to whether the inbound and outbound ports are enabled for packet intercept. If so, a source and/or destination media access control address is compared to a list of configured intercept addresses. If a match is found, a copy of the packet is diverted to an intercept receiver and the original packet is forwarded to its intended destination.
