Abstract
The present disclosure pertains to systems and methods of monitoring communication devices and communication links in a software-defined network (SDN). Network packets may be colored or tagged for routing to a packet analyzer. A VLAN bitmask may be added to a packet to identify the packet for inspection and, optionally, provide origin information identify a switch and/or port of origin. Port mirroring may be utilized and/or eventual routing of network packets to their original destination may ensure that network traffic is not disrupted. In one example, a most significant bit of a VLAN bitmask may be used by a match rule to identify packets intended for a packet analyzer without regard to original packet routing instructions and/or packet content.
