System and method for extending ports

A network switching device comprising

• a control unit;
• a port coupled to the control unit and configured to couple the network switching device to a device using a network link;
• the control unit configured to:
• receive a data packet from the port;
• determine whether an indication that a first rule applies to the data packet is in a header of the data packet;
• and
• determine whether a second rule applies to the data packet.

An information handling system comprising:

• a first port of a subordinate switch coupled to a second port of a parent switch by a network link;
• the subordinate switch comprising:
• a first control unit coupled to the first port and a third port;
• the first control unit configured to:
• receive a data packet from the third port;
• identify an information related to the data packet;
• crosscheck the information with a first list;
• create a header including data that represents the results of the crosscheck;
• create a new data packet which includes the header and the data packet;
• and
• send the data packet to the parent switch;
• the parent switch comprising:
• a second control unit coupled to the second port;
• the second control unit configured to:
• receive the data packet from the second port;
• determine whether a preliminary drop indication is provided in the header of the data packet;
• identify a second information related to the data packet;
• and
• determine whether the second information is part of a second list.
