Expansion of packet mirroring functionality

A networking device, comprising:

• a mirror-condition trigger subsystem to determine whether a packet meets a mirror trigger condition based on a first mirror criterion;
• a plurality of mirror passages;
• and
• a mirror-passage-selection subsystem to use a flexible hardware circuit to, in response to the mirror-condition trigger subsystem determining that the mirror trigger condition is met, select, from the plurality of mirror passages, a particular mirror passage based on a second mirror criterion and send the packet to the selected mirror passage;
• wherein the selected mirror passage is to generate a replicate packet and process the replicate packet;
• wherein the mirror-passage-selection subsystem is to use the flexible hardware circuit to modify the second mirror criterion based on user instructions stored in a memory associated with the networking device;
• and
• wherein, subsequent to modifying the second mirror criterion, the mirror-passage-selection subsystem is to select a different mirror passage based on the modified second mirror criterion to send a subsequent packet meeting the trigger condition.
