Abstract
Techniques are provided for retrieving entries from a routing table or a forwarding database in a distributed network switch. The forwarding database includes match and mask registers used to compare routing entries and return matching routing entries to a requesting management controller. The forwarding database uses a separate timeout value associated with the forwarding database to avoid timeout errors for general register operations, and allows for an asynchronous dump operation of routing entries.
