ABSTRACT:
A network device may include logic configured to receive a packet from a packet forwarding engine, create a flow ID for the packet, determine whether the flow ID matches one of a plurality of flow IDs in a table, determine whether the packet is associated with a flow to be sampled, sample the packet and additional packets associated with the flow that are received from the packet forwarding engine when the flow is to be sampled and transmit the flow ID and the sampled packets via a switch to an interface.
