Abstract:
Systems and methods are disclosed to forward packets not passed by criteria-based filters in packet forwarding systems. The disclosed embodiments include one or more Not Passed By Criteria (NPBC) filters that are defined for input ports along with one or more criteria-based filters, such as for example, Pass by Criteria (PBC) filters and/or Deny by Criteria filters (DBC), that forward packets not passed by these criteria-based filters. NPBC filters include, for example, Pass Unmatched PBC filters associated with PBC filters and configured to forward packets not passed by PBC filters and/or Pass Matched DBC filters associated with DBC filters and configured to forward packets not passed by DBC filters. Using one or more NPBC filters within the disclosed embodiments, packet data that is not being passed along to output ports by the criteria-based filters can be easily passed to one or more designated output ports.
