Abstract
A system and method for freezing a processing unit to facilitate on-line debugging of a protocol engine within a switching node of a data transmission network. In accordance with the system of the present invention, the protocol engine includes a plurality of processing units such as an identification unit, a lookup unit, a traffic management and congestion unit, an enqueue unit, a dequeue unit, a traffic management scheduling unit, a frame transmission unit, a control unit, and a control block unit. The control block unit includes a freeze register containing multiple freeze bits, wherein each freeze bit is associated with one processing unit. In response to setting a freeze bit, resources and settings of a processing unit associated with the set freeze bit are prevented from being changed by the processing unit.
