摘要
An Ethernet network device includes a port logic module that is associated with a device port of the Ethernet network device. A packet processing module includes an ingress processing module that receives an incoming packet and that generates a control traffic tag. An ingress command execution module receives the incoming packet and the control traffic tag, generates a duplicate packet that is identical to the incoming packet, and generates a device interface code that identifies the port logic module based on the control traffic tag. A control traffic routing module receives the duplicate packet and the device interface code and forwards the duplicate packet to the port logic module. A network traffic analysis device receives the duplicate packet. The port logic module replaces a first destination header of the duplicate packet with a second destination header that is identical to a destination header of the incoming packet.
