Method and system of querying FDB (Forwarding Database) table items of chip

The invention discloses a method and a system of querying FDB (Forwarding Database) table items of a chip. The method comprises the following steps of transmitting a request for querying the FDB table items to the chip; transmitting the FDB table items stored in the chip in a CPU (Central Processing Unit) storage; and reading the FDB table items in the CPU storage. According to the method and the system, the FDB table item information can be quickly and effectively queried without a soft table, meanwhile, the speed of hardware learning is guaranteed.
