Abstract
One embodiment disclosed relates to a method of mirroring network traffic. A data packet is received by a network device, and an algorithm including randomization is applied to determine whether the data packet is selected to be mirrored. The packet is sent to a destination port, and if the data packet is selected to be mirrored, then the packet is also sent to a mirror port. Another embodiment of the invention relates to a networking device. The networking device includes at least a plurality of ports, a switching/routing engine, and a mirroring engine. The plurality of ports receive and transmit packets therefrom, and the switching/routing engine is coupled to the ports for transferring the packets therebetween. The mirroring engine is configured to apply an algorithm including randomization to select data packets for mirroring. Other embodiments are also disclosed.
