Abstract
Techniques for virtualizing hardware hash tables in a networking system are provided. In one embodiment, the networking system can maintain a plurality of virtual hash tables corresponding to a plurality of hardware hash tables in the networking system. For each hardware hash table and its corresponding virtual hash table, the networking system can intercept operations directed to the hardware hash table and apply the intercepted operations to the virtual hash table. The networking system can then selectively install and/or uninstall virtual hash table entries to/from the hardware hash table in view of the operations.
